Account Localization for Europe: Profiles, Address Formats, and GDPR-Compliant Management

Fundamentals of Account Localization in the European Context

Localization of user profiles for the European market begins with the realization that a one-size-fits-all account system cannot meet the requirements of all EU countries. Instead, you need to design your profile flexibly to accommodate country-specific fields, formats, and legal requirements. In practice, this means modularizing from the outset: basic mandatory fields like email and password remain the same, while address, phone, and preferences vary by country. A common mistake is limiting to a single address format. A customer from Portugal expects a “Morada” with “Código Postal” in the format 1234-567, while a Polish user needs “Ulica”, “Kod pocztowy” (two to six digits), and “Miejscowość”.

Another key point is language selection. In Europe, it’s advisable not only to offer a main language but also regional variants (e.g., French for France, French for Belgium, French for Switzerland). Each user should be able to set their preferred communication language independently of their location. Implement this by providing a dropdown list with all available language variants in the profile and using the set preference for all automated emails and notifications. Don't forget that field labels must also be in the local language – a German address form with “PLZ” will confuse a French user.

Localization also affects date and number formats. While in Germany, February 1, 2025 is written as “01.02.2025”, in Sweden it’s “2025-02-01”. In the profile, format birth dates or other date fields according to the language setting. The same applies to phone numbers: the international format with +49 (DE) or +33 (FR) is recommended for all EU countries, but input should support country codes.

Recommendation: Conduct a country-specific requirements analysis for all EU countries where you expect users. Create a profile template for each country with field schema, language variants, and format specifications. Test the forms with real users from each country before going live. Plan regular updates as address formats (e.g., in Ireland or Malta) can change. Remember: an account that doesn't match local expectations leads to frustration and abandonment – avoid this mistake through careful localization.

GDPR Requirements for Personal Data in the Profile

The GDPR sets strict rules for the collection and management of personal data. In the context of account localization, you must ensure that every field in the profile has an explicit purpose and that data minimization is observed. This means: only request data necessary for contract performance or legal obligations (e.g., billing address). Optional fields like date of birth or occupation can be offered, but with a clear statement of voluntariness and the ability to delete them at any time. In practice, it makes sense to mark mandatory fields with color or an asterisk – but ensure this doesn’t lead to overwhelm.

A GDPR-compliant profile must also obtain consent for data processing transparently. Opt for a two-step registration: first step only basic mandatory fields (name, email, password), second step address or further details – each combined with an opt-in for processing. Avoid pre-checked boxes, as these are not permitted under the GDPR. A practical example: when capturing the delivery address, indicate that it is necessary for shipping and will be stored for 3 years (legal retention period).

Data management also includes the right to deletion and rectification. Your system must allow the user to edit their profile independently – a simple link to the account area is sufficient. Ensure all fields are editable and changes are logged (audit trail). For information requests, you must be able to respond within one month. Tip: implement an export tool (CSV/PDF) for the user to download their own data.

Recommendation: Have your profile logic reviewed by a legal advisor for GDPR compliance, especially for cross-border data storage. Create a deletion schedule matrix: which data is deleted when? (e.g., profile data 30 days after termination, invoice data 10 years). Offer the ability to withdraw consent and delete data within the profile. Consider data processing agreements: if you use cloud services outside the EU, you must conclude standard contractual clauses. A continuous GDPR process is better than one-time measures.

Country-Specific Address Formats and Their Variants

Address formats vary considerably across the EU. While Germany and Austria use the order 'Street House Number, Postcode City', many countries employ different structures. For example, in Spain, the 'Calle' with number comes first, then 'Piso' (floor) and 'Puerta' (door), followed by 'Código Postal' (five-digit) and 'Localidad'. In Italy, the 'Via' precedes the house number, and the 'CAP' (five-digit postcode) is written before the city. These differences must be reflected in your field schemas. A flexible approach is to use a universal address block with multiple optional lines that are populated differently depending on the country.

Specifically, implement this best with a country-specific template. Select the user's country (either via IP geolocation or manual selection) and display the appropriate fields accordingly. Example for the United Kingdom: 'Address Line 1', 'Address Line 2', 'Town/City', 'County' (optional), 'Postcode' (e.g., SW1A 1AA). For Belgium: 'Rue/Straat' and 'Numéro', then 'Code postal' (four-digit) and 'Localité/Gemeente'. Pay attention to capitalization: In the Netherlands, the city is written in uppercase, while in Germany it is written normally.

Another critical point is postcode formats. German postcodes are five-digit, French are also five-digit, but Polish consist of five digits in the format XX-XXX. Swiss postcodes are four-digit, while Irish 'Eircode' comprises seven characters (e.g., A65 F4E2). Therefore, validate input country-specifically: For Germany, check for five digits; for Poland, the pattern 'XX-XXX'. Provide input assistance, such as a tooltip with the expected format. Also consider special cases like 'Cedex' in France or 'Apdo.' (Apartado) in Spain.

Recommendation: Create a list of all EU countries with their official address formats (source: e.g., Universal Postal Union). Implement a plugin that dynamically adjusts the address form based on country selection. Test the validation logic with real addresses from each country. For example, separate fields for 'House Number' and 'Street' are common in many countries, but also offer a combined field (e.g., 'Street and Number') for countries like Portugal, where the house number comes after the street. Avoid restrictions to only one address line, as this leads to many problems in practice. Also plan an 'other' category for special cases.

Language and Region Settings for User Profiles

When registering a new user, the preferred language and region should be queried as early as possible. This can be done either through an explicit selection on the registration page or by automatic detection based on the user's IP address. However, automatic detection is only an initial suggestion: the user must be able to change the settings at any time, particularly because IP geolocation is not always precise (e.g., with VPN usage or corporate networks).

Language and region settings determine not only the UI language, but also the display of date formats (e.g., DD.MM.YYYY in Germany vs. MM/DD/YYYY in Ireland), currencies (Euro with two decimal places vs. Forint without decimal places), and payment methods. Therefore, in your user profile, you should provide a dropdown menu or selection list for language and region, ideally with a search function, as there are 24 official languages in the EU.

It is recommended to group language selection by country: if a user selects 'German', you could automatically suggest 'Germany' as the region, but allow the choice of 'Austria' or 'Switzerland'. This distinction is important because address formats and terms differ ('Postleitzahl' in DE, 'PLZ' in AT, 'Postleitzahl' with four-digit mention in Switzerland). Store the preferences in the user database as ISO codes: language according to BCP 47 (e.g., 'de-DE', 'en-IE') and region according to ISO 3166-1 alpha-2.

Ensure that the initial language selection is not intrusive. Offer a way to switch language on every page – via an icon with flag or language abbreviation. Tip: Do not use only flags for selection, as these can be politically sensitive (e.g., a flag for 'English' as British or US flag). Combine flags with the language name in the respective native language. Also plan regular checks of translation consistency to ensure that localization is not forgotten for new UI elements.

Adapting Profile Fields to Local Contexts

Address formats vary significantly across Europe, even within the same language. A German profile looks different from a Spanish or Polish one. Instead of a rigid, one-size-fits-all form, you should provide dynamic profile fields that adapt to the user’s region. Implement logic that displays, requires, or labels different fields based on the selected country.

Examples: In Germany and Austria, fields like “Street” and “House Number” are common, while in Ireland addresses are often entered as “Address Line 1” and “Address Line 2” with optional “Townland”. In Poland, the “Województwo” (voivodeship) is not mandatory for the postal code but is helpful in practice. In Belgium, the distinction between French and Dutch municipality names matters. In Spain, fields ask for “Calle”, “Número”, “Piso”, and “Puerta”. A flexible field set with placeholders for local specifics is therefore essential.

Create a field template for each country. Use a data structure that defines for each country which fields are displayed, whether they are required, and their order. Avoid offering too many generic fields like “Address Line 1, 2, 3” – this confuses users. Instead, provide precise labels that match local practice. Names should also be in the local language (e.g., “PLZ” in Austria, “Postal Code” in Ireland).

Plan regular updates to this template database, as postal code systems or format requirements can change (e.g., the introduction of new postal codes in Lithuania in 2022). Also consider regional naming differences like “Departamento” in France vs. “Región” in Spain. An external localization database or address validation partner can assist here. Remember that changes to templates also require adjusting translation strings – coordinate this with your localization team.

Validation of Streets, Postal Codes, and Cities

Correctly validating address data is a critical component of account localization. Incorrect entries lead to shipping returns, customer frustration, and unnecessary support costs. Therefore, you should implement country-specific validation rules based on official postal or address databases.

Start with the postal code: In Germany, the format is five-digit numeric (e.g., 10115). In Austria, four digits; Switzerland, four digits; France, five digits; Poland uses the format XX-XXX. Use per-country regex patterns to validate input. Provide error messages in the user’s language, e.g., “Please enter a valid five-digit postal code.” for Germany. Avoid generic messages like “Invalid format”. For moves or new registrations, offer an autocomplete function that suggests the city based on the entered postal code – many postal services provide such APIs.

For street names, do not impose a strict length limit, as long compound names can occur (e.g., “Rathausstraße” in Berlin vs. “Calle Mayor de la Villa de Madrid” in Spain). A 255-character limit is sufficient in practice, but avoid shorter limits. For house numbers, allow alphanumeric characters (e.g., “12 A” in Sweden or “8/2” in Poland). For city/locality, validate spelling against a reference dataset (e.g., the official municipality list of the respective country). Notify the user if the entered city does not match the postal code, but do not force correction, as there are valid exceptions (e.g., P.O. boxes or large customer addresses).

Implement server-side validation as a safeguard against bypassed client-side checks. Store address data in a structured format, ideally with separate fields for each component. This allows you to perform address correction or enrichment later on. Be mindful of GDPR: Personal address data is especially sensitive. Process it only for specific purposes and delete it after the statutory retention period. Have your validation logic reviewed by a data protection officer to ensure legal compliance.

Managing multiple addresses per user account

In European e-commerce and services, it is common for users to want to manage multiple addresses – such as delivery addresses for different locations, billing addresses, or alternative contact addresses. Flexible address management improves the user experience and reduces errors in orders. In practice, you should therefore set up a system that allows the creation, editing, and deletion of multiple addresses per account. It is advisable to assign each address a unique type (e.g., 'Private', 'Business', 'Invoice') and a marker as the default address for specific purposes. Technically, it is recommended to use a separate database table for addresses that is linked to the user account via a foreign key relationship.

When designing input forms, you should consider country-specific address formats. Provide validation for each field, such as street, house number, postal code, and city, based on the selected country. For example, Germany expects the postal code before the city, while in the United Kingdom the postal code is often entered separately. Use established libraries or APIs for address validation that are regularly updated. For the user interface, we recommend a clear list of saved addresses with buttons for editing and deleting. The ability to define an address as default should be achievable with one click.

From a data protection perspective, it is important to collect only the address data necessary for the respective purpose. Do not query fields you do not need – such as a second address line if you do not evaluate it. Always store which address is used for which purpose (delivery, invoice, correspondence). Delete addresses that the user no longer needs promptly upon request. Document the deletion in the system to later prove that data has been removed in accordance with the GDPR.

Practical recommendation: Implement an address management module with the following core functions: adding a new address with type specification, editing existing addresses, setting a default address per usage context, and deleting addresses with a confirmation dialog. Validate each address client-side and server-side based on the selected country. Test the user interface with real addresses from various EU countries. Note that address data may only be used for the stated purposes under the GDPR. We recommend having a legal advisor review the permissibility of storing multiple addresses.

Secure storage and encryption of profile data

The GDPR requires that personal data be protected by appropriate technical and organizational measures. For user profiles – especially addresses, payment information (if stored), and communication data – this means encrypting them both during transmission and at rest. In practice, it has proven effective to encrypt sensitive data fields in the database using strong algorithms such as AES-256. The key should be stored separately from the data, for example in a hardware security module (HSM) or a secure key management service. Ensure that only authorized services can access the decryption.

For the transmission of profile data between client and server, TLS (Transport Layer Security) version 1.2 or higher is standard. Use HSTS (HTTP Strict Transport Security) to enforce encrypted connections only. When storing passwords, never use plain text or insecure hashes like MD5. Instead, use a slow hash algorithm such as bcrypt, scrypt, or Argon2. Additionally, store a random salt per password. For authentication, we recommend implementing multi-factor authentication (MFA) for particularly sensitive profiles.

Access controls are another central component. Grant users access only to their own profile data. Administrators should have different rights depending on their role (e.g., read-only, only manage addresses). Implement an audit log that records all accesses and changes to profile data – with timestamp, executing user, and type of action. Regularly check logs for anomalies. For encrypting database fields, column-level encryption is suitable. Alternatively, the entire database can be encrypted (Transparent Data Encryption), but the application code must then manage the decryption.

Finally, you should define a data retention policy: Delete profiles that have been inactive longer than necessary in accordance with your privacy policy. Perform regular security updates and penetration tests. Instruct your developers on secure coding guidelines. Since the requirements vary depending on the type of data, we recommend having the specific implementation reviewed by an IT security expert and legally verified to ensure that the measures taken meet the requirements of the GDPR.

Consent management and purpose limitation according to GDPR

The GDPR stipulates that personal data may only be collected for specified, explicit and legitimate purposes (purpose limitation). For each user profile, you must clearly define for which purpose which data is needed – for example, for contract fulfillment, communication, or personalization of content. User consent is often the legal basis, especially if you intend to use data for marketing or profiling. In practice, you should therefore implement a consent management system that covers the following points: informed consent, active consent (no pre-checking), and the ability to withdraw at any time.

Design the consent interface so that the user can see exactly what they are giving their data for. Use clear, understandable language and avoid vague formulations. Offer separate consent options for different processing purposes – for example, one for account management and a separate one for receiving newsletters. Store each consent with a timestamp, a precise explanation, and information on whether the user confirmed via double opt-in. You must retain these records for the duration of processing and be able to present them to the supervisory authority upon request.

The withdrawal option should be as easy as granting consent. Integrate an overview of all granted consents into the user profile, with the option to withdraw them. After withdrawal, you must immediately cease data processing for the corresponding purpose. However, note that data still required for other purposes (e.g., contract fulfillment) does not need to be deleted. The deletion of personal data after withdrawal should be automated or follow a clearly defined process.

Practical recommendation: Develop a consent module that includes the following functions: display of purposes at registration, storage of consent data in a separate database table, the possibility of withdrawal via the user account, and a dashboard for administrators to view consent statistics. Always link to the current privacy policy. Train your employees in handling consents and withdrawals. Since the interpretation of the GDPR can vary from country to country, we recommend having the consent management system reviewed by a legal advisor who is also familiar with the local specifics of the markets you serve.

Data portability and deletion of profile information

The GDPR grants users the right to data portability (Art. 20) and deletion (Art. 17). For localized profiles, this means you must implement both technical and organizational measures to exercise these rights in a timely and country-specific manner.

For data portability, implement an export mechanism that provides all profile-relevant information – including addresses, language preferences, and stored consents – in a machine-readable and widely used format such as JSON or CSV. Ensure that the export structures the data so that it can be imported into another system without loss of information. In practice, it has proven effective to generate the export upon request within 30 days and make it available to the user via a secure download portal. Consider that if there are multiple addresses or historical data, a clear designation (e.g., "current" vs. "archived") is necessary.

Deletion of profile information requires a multi-step procedure. First, the deletion request must be clearly identified and the user authenticated. Then, you must delete not only the active database entries but also the associated backups and log data, unless they are protected by statutory retention obligations (e.g., commercial law provisions). Plan automated scripts that run regularly across all storage systems for this purpose. Note: Data that you must continue to process on another legal basis (e.g., contract fulfillment) is exempt from deletion – this should be clearly communicated to the user.

Practical recommendations: Define clear deadlines for processing portability and deletion requests and monitor them via a ticket system. Conduct regular deletion tests to ensure no data residues remain. Document the processes separately for each localization, as national exceptions (e.g., extended retention periods in Austria) may exist. For legal questions, always consult your legal department or an external data protection officer.

Integration with CRM and ERP Systems

Synchronizing localized user profiles with CRM and ERP systems presents unique challenges, as these systems often use different data formats and field structures than your web application. A typical scenario: a customer from France enters their address with fields "Address 1" and "Address 2", while the ERP only provides a single address field. Here, a mapping logic must correctly merge or split the data.

Start with a detailed analysis of the data fields in both systems. Create a mapping that covers all relevant fields: first name, last name, email, language, address components (street, house number, postal code, city, country), phone numbers, and consent status. Pay special attention to country-specific peculiarities such as the additional "Cedex" address line in France or the "County" field in Ireland. Validate the data before transferring it to the target system to avoid transmission errors. Practical example: when integrating with SAP, it is common to transfer address data via IDocs (Intermediate Documents) – here, you must ensure that the segment structure (e.g., E1ADRS) is correctly populated.

Decide whether the integration should be real-time (e.g., via REST API) or batch-based. Real-time integrations are suitable for frequent changes but require a stable network connection and error handling. Batch processing is more robust but can introduce delays. In practice, a hybrid approach has proven effective for profile data: critical changes (e.g., delivery address) are synchronized immediately, while less urgent data (e.g., language preference) is reconciled daily via batch.

Test the integration with realistic datasets from all target countries. Use both valid and deliberately erroneous data (e.g., incomplete addresses) to verify error handling. Document all mapping rules and implement change management to prevent disruptions during system updates. When selecting the interface, consult the target system documentation and, if necessary, involve an integration expert.

Test Strategies for Localized User Profiles

To ensure the quality and correctness of localized user profiles, a structured test strategy is essential. This strategy should cover both functional and non-functional aspects and be integrated into the regular development cycle.

First, define test scenarios for each target country. For example, for a German address, verify that the system validates the postal code as 5 digits; for a UK address, validate the format "SW1A 1AA" (alphanumeric with space). Create a test data table with realistic and edge cases: very long street names, addresses with special characters (e.g., "München, Straße, 123"), case variations, and missing fields. Automate these checks using unit tests that run on every build. In practice, it is advisable to write a separate test class for each country that covers all relevant validations.

In addition to data validation, test the correct display of profile fields in all supported languages. Ensure that labels, placeholders, and error messages are translated and that no text overflow occurs. Use visual regression tests that compare screenshots to reference images. Also pay attention to the correct field order (e.g., in Hungary: last name before first name) and the proper formatting of phone numbers (country code, digit grouping).

Another important area is GDPR compliance. Test whether consents are stored correctly and fully exported. Simulate deletion requests and verify that data is actually removed from all systems (including logs and backups). Use a separate test environment that mirrors the production structure without real personal data.

Finally, conduct load tests to check behavior under many simultaneous profile changes, especially during synchronization with external systems. Document all test results and update test cases with each new localization or legal change. Close collaboration with local testers or native speakers helps identify cultural nuances.

Checklist for GDPR-compliant profile management

A GDPR-compliant profile management requires systematic processes. Use this checklist as a foundation for your implementation:

1. **Determine the legal basis**: For each profile field, document the legal basis for processing (Art. 6 GDPR). Typically, contract fulfillment (Art. 6(1)(b)) or legitimate interest (Art. 6(1)(f)) applies. For marketing consents, use opt-in procedures. Maintain a processing activity list.

2. **Implement data minimization**: Only collect fields that are strictly necessary for the service. Avoid optional details such as date of birth or gender unless legally required (e.g., age verification for alcohol sales). Regularly review whether stored data is still needed.

3. **Integrate consent management**: For cookies or profile fields without contractual necessity, obtain active consent. Store consents with timestamps and proof of user action. Allow revocation at any time, which adjusts profile processing accordingly (e.g., deletion of marketing data upon revocation).

4. **Access and deletion processes**: Ensure users can view, export (data portability under Art. 20 GDPR), and delete their profile data via a self-service portal. Implement a form-based procedure for requests that cannot be automated. Response time maximum 30 days.

5. **Ensure data security**: Encrypt profile data at rest (e.g., AES-256) and in transit (TLS 1.3). Conduct regular penetration tests. Restrict internal access to the minimum necessary for task fulfillment (need-to-know principle).

6. **Documentation and evidence**: Record any changes made to profiles (audit trail). Document your deletion and retention periods. Conclude a data processing agreement with processors (e.g., hosting providers).

7. **Regular review**: Conduct an internal data protection impact assessment for profile management at least annually. Train employees in handling personal data. Update documentation in case of legal changes (e.g., new EU Data Governance Act).

Involve your legal department or an external data protection officer to ensure compliant implementation.

Outlook: Trends and further development of localization

The localization of account profiles is constantly evolving. Three trends are emerging:

1. **Zero-party data as standard**: More and more users expect companies to process only data that they actively provide. Instead of automatically adopting addresses from other sources, services rely on voluntary disclosures with clear added value (e.g., personalized product recommendations). AI-powered forms can facilitate input (e.g., suggestions for address components based on a few letters) without undermining the user's data sovereignty.

2. **Decentralized identities (Self-Sovereign Identity)**: Technologies such as blockchain-based wallets allow users to have profile-relevant data (name, address, age) signed by a trusted party and only transmit a proof of identity. This reduces storage of personal data at the service and facilitates GDPR-compliant management. Initial European ID wallet projects (EU Digital Identity Wallet) indicate the direction.

3. **AI-powered adaptive localization**: Instead of static profiles, systems will automatically detect the user's region or language preference and dynamically adjust profile fields. For example, in Finland, the social security number is added as a mandatory field in the address, while it is irrelevant in France. The challenge remains transparent communication of this dynamic to the user.

4. **Hyperpersonalization with data minimization**: Technically, it is possible to generate highly personalized content from just a few details (e.g., zip code). However, in practice, you should critically assess whether this personalization is proportionate to the privacy intrusion. Use anonymization techniques (Differential Privacy) to analyze profiles without identifying individual users.

5. **Automated compliance**: Tools that monitor changes in data protection legislation and automatically adjust profile management are becoming increasingly affordable. Ensure such systems are certified by independent bodies and do not create security vulnerabilities.

As a company, you should monitor these trends but integrate them into your own architecture only after careful review and involvement of your data protection team.

Pitfalls and Common Mistakes in Account Localization

The localization of user profiles involves some typical pitfalls that can lead to user frustration or legal issues. A common mistake is assuming that a uniform address format is sufficient for all EU countries. In practice, not only field labels differ, but also the order and necessity of details such as 'County' in Ireland or 'Province' in Spain. If these are ignored, users may not receive correct delivery or feel unaddressed.

Another problem area is insufficient consideration of GDPR in profile management. Often, consents for processing profile data are not obtained separately from other purposes, which can lead to violations of the prohibition of coupling. Also, deletion of profiles after an account deletion request is not always fully implemented, especially when data remains in backups or CRM systems. This requires careful coordination between systems to ensure data is actually deleted.

Practical difficulties also arise in the validation of address data. While German postal codes are five-digit, Austrian ones have four digits, and Belgian ones also four, but with an optional letter. A simple regular expression is not enough to cover all variants. Instead, country-specific validation routines should be implemented based on official data sources such as postal services.

The linguistic localization of profile fields is also often underestimated. Even if the user interface is translated, field labels like 'Vorname' in Germany but 'Prénom' in France may appear. If internal processing then relies on fixed field names, data inconsistencies arise. A well-thought-out mapping strategy between UI and database helps avoid such problems. It is advisable to involve translations early in the development process and test with native speakers.

Finally, insufficient consideration of exceptional cases such as special characters in names (e.g., 'Müller' or 'Sørensen') or multiple addresses during moves leads to dissatisfied users. A flexible profile model that allows optional fields and repeatable address blocks is therefore a key success factor for account localization.

Tools and Automation for User Profile Localization

Manual localization of user profiles is time-consuming and error-prone. Modern tools and automation methods can make the process more efficient without compromising quality. A central tool is Translation Management Systems (TMS), which manage translations for profile fields, error messages, and validation texts. They often offer integrations with development environments and enable reuse of translations across multiple projects.

For address validation, there are specialized APIs and services that can check and normalize country-specific formats. Examples include integration with postal services such as Deutsche Post, La Poste, or Correos, which provide official address databases. These services can check in real-time whether an entered address exists and is correctly formatted. However, it should be noted that the use of such services must be reviewed from a data protection perspective, especially when personal data is transmitted to third parties.

Automation tools for generating country-specific forms can also be helpful. By using configuration files that define the required fields, their order, and validation rules for each country, the code becomes more maintainable. Frameworks like Angular, React, or Vue.js support dynamic forms that display different fields depending on the selected country. This reduces the effort for manual adaptation per country.

Furthermore, continuous integration pipelines can be used to automatically integrate localization updates into test environments. This ensures that changes to translations or validation rules can be tested immediately. For GDPR-compliant management of consents and profile data, Consent Management Platforms (CMP) are suitable, which centrally manage consents and link them with account data.

When selecting tools, companies should pay attention to support for all required EU languages, easy integration into existing systems, and compliance with GDPR. Open-source solutions often offer flexibility, while commercial products provide more extensive support and maintenance services. A proof-of-concept with the selected tools helps identify potential pitfalls early on before full integration begins.
