Is SSN required for beneficial owners to onboard a new merchant?
Last updated: October 21, 2025
Context
Onboarding a company as a GrailPay merchant requires that they undergo our KYB verification review.
Answer
To pass KYB, a Social Security Number (SSN) is required for at least one beneficial owner of the merchant being onboarded. his is necessary for our compliance and underwriting policies.
Full nine-digit SSN is preferred
Last 4 digits of SSN may be accepted as an alternative, but If identity verification on the beneficial owner fails with last just the last 4 digits, the KYB review on the merchant will not succeed.
