In most cases, this is determined based on data submitted with the purging of the check file to the UPCF. The claimant may need to work with the Division staff to identify the agency if data is not available.
The agency will review the claim based on established protocols of evidence including, but not limited to: matching social security number to agency records; copy of original-dated check; payment history indicating no re-issuance of check by the agency; and matching address to agency vendor file.
