Identity checks
Include fields for supporting ID uploads and enable third-party KYC or TIN-match integrations to validate the SSN and reduce mismatches.
Accurate SSN verification prevents tax reporting errors, avoids backup withholding, and reduces identity-fraud exposure while supporting compliance with IRS and financial-sector requirements.
Common requesters and signers include employers, financial institutions, tax preparers, and third-party payers who must verify TINs before reporting.
The form is also used during account opening, loan underwriting, contract payouts, and vendor onboarding where correct SSN/TIN data is required.

| Authentication level | Email + SMS code or knowledge-based verification |
