Vendor TIN verification

Overview

Ramp enables Bill Pay users to securely collect tax information from vendors and to maintain that information directly within Ramp. Ramp also automatically verifies your vendors’ TIN (Taxpayer Identification Number) with the IRS (US) or VIES (EU) to ensure you’re filing taxes correctly.

How does this work?

Add Business Legal Name and TIN

Add tax information for your vendors or request the info directly from the vendor within Ramp. Note that Ramp requires the business legal name and TIN of your vendor to complete this verification.

You can filter the Vendors table by tax verification status.

Checks Run Automatically

Ramp will automatically verify your vendors’ tax information with the IRS or VIES once all tax information has been added. View a vendor's profile and go to tax details to view TIN verification status.

Failed Verification

Verification most often fails due to an incorrect TIN number, and sometimes incorrect legal name. A failed TIN Check does not block payments or1099 filing. You can file after re-entering the TIN and acknowledging a warning.

  1. Check that the business legal name and Tax ID in Ramp exactly match the information on the vendor's IRS-issued documentation (Social Security Card for SSNs, and CP 575 letter for EINs), including upper/lower case, symbols, and punctuation placement.
  1. If the vendor is international, check that the country matches the tax authority that issued the foreign tin.
  2. If TIN verification still fails, reach out to your vendor to ensure their information on file is accurate.

You will not be informed when a TIN check fails, but if a vendor adds their own tax details, they will receive an email about the failure.

Ramp also enforces country-specific Foreign TIN rules. For example, Poland VAT numbers must be exactly 10 digits.
