TIN Fingerprints

In Tin Verification request, Form 1099 request or any other request where you pass a TIN, we will always return a masked tin and a tin fingerprint.

  "tin": "*******00",
  "tinFingerprint": "tinFingerprint_samplehy2BWO6JJG"

The tinFingerprint is your app-specific token that points to a unique 9 digit tin value. Now that you have a tinFingerprint, you can use it:

  • in lieu of the plain text tin value in subsequent API calls that require a TIN.
  • when troubleshooting with our support team.


Use the tinFingerprint when talking to support

Please do not send us plain text tin values when communicating with our support team.
