Why do you need my TIN/SSN?

Public, searchable exclusion lists only provide names of individuals and entities. Most agencies will allow you to use a secondary identifier (most commonly TIN/SSN) to call and verify a name match. This allows us to rule out any name-only matches that could otherwise prevent you from getting paid by your customer. We also verify vendors’ TIN number matches the IRS records to help improve the accuracy of your customer's vendor data, especially with regards to their tax filings.
