Questions and anwers on ADDRESSFACTORY Version 3.

Which product options are available?

  • ADDRESSFACTORY AUTOMATIC for regular updates (batch matching)
  • ADDRESSFACTORY DIRECT – matching in real time (single matching)
Can private and company addresses be processed using ADDRESSFACTORY?

The range of services has a modular structure. When checking the postal plausibility in the BasicAddressCheck module, it is irrelevant whether it is company or private addresses that are being processed. In the name check (FormalNameCheck) and the deliverability check (PremiumDeliveryCheck) of the relevant addressee, however, both the databases used as reference and the matching algorithms are optimised for processing private addresses. The processing of company addresses therefore generally delivers suboptimal results.

Are all ADDRESSFACTORY modules automatically used?

You decide which modules you wish to use in your matching for the ADDRESSFACTORY WEB and TAPE product options. Only BasicAddressCheck is mandatory. For all modules other than BasicAddressCheck, FormalNameCheck is also mandatory.

Your advisor at Deutsche Post Direkt will be happy to inform you about the relevant options and will provide you with the appropriate configurations for your matching for the ADDRESSFACTORY AUTOMATIC and DIRECT product options.

Which modules are currently available?
  • BasicAddressCheck (checks an address for the correct street, town/city and postal code).
  • FormalNameCheck (correction of names and adding of titles and salutations).
  • PremiumDeliveryCheck (person-based, household-based and/or building-based checking of delivery information).
  • MoveProfessional (provides relocation addresses).
  • DoubleClean (recognition and marking of double entries). This module is not available for ADDRESSFACTORY DIRECT.
  • FileMatch (address match with own and/ or predefined negative files such as Robinson list or a fake names list.)
  • GeoMatch (address enhancement with geographic data).
  • PhoneMatch (enhancement with telephone numbers).
  • LocalMatch (enhancement with socio-demographic and micro-geographic information).
What information should my file contain?

The following matching columns are relevant for a successful matching:

  • a unique ID, that you can later use to allocate the data record again
  • first name
  • last name
  • street
  • house number
  • postal code
  • town/city
  • where possible, specification of the district, in order to resolve any ambiguities in the address
What file formats can ADDRESSFACTORY match?

The following file formats for input and output files:

  • Text (variable column width):
        - commas                 ,
        - semicolons            ;
        - tildes                     ~
        - hash symbol         #
        - colons                   :
        - tabs
        - vertical bars         |
  • Text (fixed column width)

The following character sets are supported: ISO-8859-1, ISO-8859-15, US-ASCII, WINDOWS-1252, UTF-8 and IBM85.

What do I receive as a result file?

After batch matching, you will receive a ZIP archive with your result data in your download folder or it will be sent to an (S)FTP server specified by you using an FTP forward. It is also possible for the data to be forwarded to another registered user of Deutsche Post Direkt’s online services.
In addition to information from the system – number, data and time of the matching – the file name also includes the name of the input file to make it easier to identify. The content of the ZIP archive varies according to your agreements with Deutsche Post Direkt. In many cases, we will provide you with an overall result file in the archive. Alternatively, we can also provide you with an archive containing various partial results – e.g. deliverable and non-deliverable data records. For the ADDRESSFACTORY DIRECT option, you will receive the results directly for each data record.

Can I compare multiple files with one another?

With the ADDRESSFACTORY batch options, you can have multiple files cleansed if you upload multiple files.
If a duplicate check is performed on your data, the priority order of your files will have an impact on the identification of header duplicates. Your own negative files always have priority over your own positive files.

Can I compare my data against negative files?

We process negative files with the same matching settings with which we also process your positive files. This is absolutely essential in order to be able to reliably identify matching records between positive and negative files. It is not possible to download a cleansed negative file. Please note: If you upload a negative file to the system, a duplicate check is mandatory.

What does it cost to cleanse negative files?

Your positive files are compared against your own negative files in the DoubleClean module. For this, EUR3.00/1,000 input addresses will be charged in addition to the costs for the positive file.

Can different configurations be used?

Different configurations can be used in both the interface solution (ADDRESSFACTORY AUTOMATIC and ADDRESSFACTORY DIRECT) and the online interface ADDRESSFACTORY WEB. During test operations a maximum of three configurations can be used.

How long does Deutsche Post Direkt store the personal data from my matching?

As a general rule, Deutsche Post Direkt stores the personal data from your matching for 90 days from receipt.
If other deletion periods are required, these should be arranged separate.

How does Deutsche Post Direkt verify the services provided with ADDRESSFACTORY?

In general, Deutsche Post Direkt returns every data record uploaded to the customer. In so doing, every data record is enhanced with a “Status” field in which the status key is saved. This status key provides detailed information on how Deutsche Post Direkt has rated the relevant data record and where this has been changed for what reason.

How are addresses protected against misuse?

To ensure the secure transfer of address data, when using Deutsche Post Direkt’s online services (, your data is protected with 128-bit SSL encryption when it is transmitted over the Internet.
You can recognise the SSL protocol from the "https" in front of the URL of the selected
