This error means that AddressFinder encountered an issue when creating the Processing Acknowledgement Form. There are a few different reasons why this error will happen, so please check the following first:

1. The address on the My Organization account must be a complete and valid physical address. This means it must not be a PO Box and it must be valid with the USPS. You can check this and make changes by following these steps:
  • Log into eTapestry
  • Click Management > My Organization
  • In the Persona Information tile, ensure your address is not a PO Box and all other address fields, such as City, State, and Postal Code are valid
  • If you make any changes click Save And under Tasks
2.  The NAICS code submitting must be valid for your organization. If you don't know this code, or would like to verify it, visit this directory.

If you've verified the above items but the AddressFinder service continues to fail with error code 1211 please contact support and reference this article ID.
