Consent Based SSN Verification (CBSV) is the superlative methodology to validate Personally Identifiable Information (PII). CBSV matches the applicant Name, Date of Birth, and Social Security Number (SSN) against the official SSA Master File and Death Index. Each CBSV request is returned with an instantaneous “Successful”, “Unsuccessful”, or “Deceased” result. The SSA plans to launch Electronic CBSV (eCBSV) in May of 2021 which allows E-Signature.
