You can submit a TIN check by passing a Business Name or an Individual name along with their EIN or SSN accordingly. It is an asynchronous API call in which a request-id is provided in the response. Need to use the GET API call by ID (request id) to see the result. Please check the How API Works section on how the asynchronous API life cycle works.

Duplicate Requests - In Review (Code 10)

If multiple requests are submitted within a 30-hour period using either the same Name with different TINs or the same TIN with different Names, the third request will be flagged as "In Review" (Code 10). These requests will be quarantined and processed manually, which may take a minimum of 30 minutes or longer, depending on the number of duplicate requests submitted. We recommend waiting for the specified period before submitting any further duplicate requests.
