Frequently Asked Questions

Get answers related to TIN Matching API questions below.

Validating TIN and name information before tax reporting helps businesses identify incorrect or mismatched taxpayer details early. This can reduce filing errors and the risk of issues that may lead to IRS notices or penalties.

No, It is not mandatory but most businesses implement it as it reduces filing mistakes and serves as evidence of reasonable cause if they are subjected to fines.

TIN matching is valid for U.S. payees who provide W-9 forms. It is not relevant for W-8 forms needed for individuals and entities abroad.

No, the API only verifies the compatibility of an already available TIN/name and cannot find any missing TIN.

Yes. We give you sandbox access so you can send test requests, see real response formats and check how your system handles matches, mismatches and errors. This way you can try Taxpayer Identification Number verification end to end before going live. Book a demo and we’ll set up your test access.

If you’re an individual, yes. An SSN is one kind of Taxpayer Identification Number, so it works fine for TIN number verification. Businesses should use their EIN instead. Just make sure the name you enter is the one tied to that number. For individuals, that’s the name on the Social Security card. For businesses, it’s the legal name linked to the EIN. A correct number with the wrong name will still come back as a mismatch.
