Address Validator Results

What do the address status codes VALID, SUSPECT and INVALID mean?

  • VALID: address is correct and deliverable.
  • SUSPECT: address is incorrect and needs corrections to be deliverable, a suggested correction is provided.
  • INVALID: address is incorrect and not deliverable - either there is no match at all in the reference data or the address is ambiguous and there are a lot of different matches. In these cases automatic correction suggestions are not available.

Address Validator List Processing

How do I validate addresses from a database, Customer Relationship Management (CRM) system or Excel?
Databases, CRM systems and Excel are capable to export data to CSV (comma-separated values) files - please see the answer to the next question for instructions on how to upload a CSV file for validation.

How do I validate addresses from Excel or a CSV file?
You can start the validation process by uploading a CSV file (Unicode UTF-8/UTF-16 format, one address per line, use comma (',') as column separator and provide these column headers: street address, address line 2, postal code, city, state, country).
Excel files must be exported to CSV first:

  • Open the file in Excel.
  • Click Menu | Save As (Other Formats).
  • Enter a name for the file and choose "Unicode Text (*.txt)".
  • Click Save.

Why does my validation task not start automatically, even though I paid the correct amount?
We use a third-party service (MyCommerce Share-It / Digital River) to manage payments. Please use the same email address both for your validation task and for the Share-It purchase, so that the task to start can be identified. If you already used a different email address, please send us an email so we can start your task manually.

Why does the list upload web form report thousands of addresses, when I only uploaded a few hundred?
Our automatic format detection tries to detect and convert files submitted in many common spreadsheet and archive formats, but this sometimes fails. If this happens, make sure you submit your list in one of the following formats:

If you have a spreadsheet, use your spreadsheet software to export the list to text/csv format.
You can check your list with our Address List Validator tool before uploading.
