An SSN Check is a U.S. identity verification service that validates a customer's Social Security Number (SSN) against trusted and authoritative data sources to help confirm their identity and reduce fraud risk.
SSN Checks are commonly used to support Know Your Customer (KYC), Customer Identification Program (CIP), customer onboarding, account opening, and fraud prevention requirements.
By validating SSNs against authoritative records and assessing the consistency of customer identity information, SSN Checks help organisations make more informed onboarding and risk decisions.
How SSN Checks Help Reduce Fraud
SSN Checks help organisations identify identity discrepancies, reduce onboarding risk, and detect potential fraud before an account is opened or a service is provided.
They can help identify:
- Invalid or incorrectly provided SSNs
- Identity mismatches and inconsistencies
- SSNs associated with deceased individuals
- Potential synthetic identity fraud
- Elevated identity and onboarding risks
These insights support stronger KYC, CIP, fraud prevention, and customer due diligence controls
