Up-to-date, well-maintained customer data is an important foundation for reliable customer communication. Trebbau checks and updates your address data, corrects inaccurate details and creates a reliable data foundation for CRM, direct marketing and mailing campaigns.
This helps your messages reach the right recipients – with the correct address and a personalised greeting.
What does data updating involve?
Customer data changes and may already contain errors or inconsistencies when it is first recorded. Incorrect postcodes, misspelt street names or mismatched names and salutations reduce the quality of a dataset.
When updating data, Trebbau checks existing details for formal and postal accuracy and corrects them wherever the available reference data allows.
The result is a more up-to-date and consistent data foundation for further processing.
Which data can be checked and updated?
Different fields can be checked depending on the dataset and its intended use.
Check postal addresses
A correct postal address is essential for reliable delivery.
Trebbau checks details including:
- Postcodes
- Towns and streets
- Consistency between postcode, town and street
- Address spelling
- PO box addresses
Discrepancies against the reference data used can be identified and corrected wherever an unambiguous correction is possible. Records that cannot be corrected automatically can be listed separately for further review.
Correct names and salutations
Incorrectly or inconsistently recorded name data can also affect personalised customer communication.
The Name Check can, for example:
- Match salutations to first names
- Correct capitalisation
- Check personalisation and salutations
- Identify and clean up duplicate name fields
This improves not only formal data quality. It also provides a more reliable data foundation for personalised communication.
Check data quality before processing
A statistical review of the supplied dataset is useful before further processing. It can reveal anomalies that may indicate errors in the data structure or import process.
Trebbau can examine characteristics including:
- Number of supplied addresses
- Regional distribution by postcode area and federal state
- Age distribution
- Distribution across women, men and businesses
- Academic qualifications and titles of nobility
- PO box addresses
- Completeness of individual fields such as customer number or ID
If anomalies are identified, we agree the next steps with you.
Post-OK: check and correct addresses
With Post-OK, Trebbau checks postal addresses against up-to-date reference data.
This includes checking the validity and allocation of postcodes, as well as the existence and spelling of towns and streets. Where unambiguous discrepancies are identified, the relevant details can be corrected and updated.
Records for which no unambiguous automated correction is possible can be listed separately.
This gives you a clear view of which addresses are postally correct and which records require further clarification.
Data updating or data matching – what is the difference?
Both services improve the quality of a dataset, but they address different aspects.
Data updating focuses on existing details within a record: are the address, spelling, name and salutation correct and usable?
Data matching compares a dataset with other datasets or reference data to identify duplicates, changes of address, deceased individuals or undeliverable addresses, for example.
The measures that make sense depend on the condition of your dataset and its intended use.
Why choose Trebbau for data updating?
Trebbau combines data processing with many years of experience in direct marketing and direct mail production. We therefore consider data quality in the context of how the data will subsequently be used.
Depending on the starting point, data checks and updates can be combined with additional data management, mailing and production services.
This creates a data foundation aligned with the processes that follow.

Frequently asked questions about data updating
A check is particularly useful before major mailing or direct marketing activities, when a dataset has not been reviewed for some time, or when there are doubts about the formal or postal quality of the stored data.
Unambiguous discrepancies can be corrected using the reference data available. If no unambiguous automated correction is possible, the affected records can be listed separately.
Yes. Checks and corrections can cover the matching of salutations to first names, capitalisation and consistency between personalisation and salutations, among other aspects.
Anomalies in the supplied dataset are highlighted. Trebbau then agrees with you which further checks or corrections would be useful for the specific dataset.
