After collecting user data, Abound makes it easy to automate the verification of your payee’s TINs (Tax Identification Numbers). Utilize the Abound Dashboard to get immediate results, or design a full automation pipeline using the Abound API.

Watch it in action


Upload a CSV containing your payee TIN data and Abound will verify up to 100,000 TINs. Results are returned in real time, removing bottlenecks in your workflow.

All TIN verifications (including those imported from the Drop-in UI Component or API) are viewable and searchable in your dashboard.


For custom or robust workflows, Abound’s TIN verification API can be used to verify millions of TINs.
