eCBSV
eCBSV (electronic Consent Based Social Security Number Verification) is a Social Security Administration service that lets permitted entities verify, in real time and with the consumer’s consent, whether a name, SSN, and date of birth combination matches SSA records. It returns a yes/no match plus a death indicator, straight from the agency that issued the number.
Why it exists
Synthetic identity fraud works by attaching a fabricated person to a real SSN, usually one with no credit history. Traditional checks compare applications against credit bureau data, which a cultivated synthetic identity has already infiltrated. eCBSV checks the combination against the issuance record itself, which a synthetic identity cannot fake. Congress authorized the service in the 2018 Banking Bill specifically to combat synthetic fraud, and it launched in 2020.
How it works in practice
The consumer provides written or electronic consent. The financial institution (or its service provider) submits name, SSN, and date of birth; SSA returns a match/no-match and a death indicator in seconds. eCBSV does not return the person’s data, only whether the submitted combination is consistent with SSA records, which keeps it privacy-preserving while killing the core synthetic-identity move.
Access runs through entities enrolled with SSA, and most banks consume it through an identity verification provider rather than enrolling directly. In a verification-first onboarding flow, the check runs invisibly during account opening.
Common questions
What does eCBSV return?
A yes/no indication that the submitted name, SSN, and date of birth match SSA records, plus a death indicator. It does not return any personal data.
Who can use eCBSV?
Permitted entities under the statute, chiefly financial institutions and their service providers, for credit and account-opening use cases, with consumer consent. Most banks access it through an enrolled identity verification provider.
How is eCBSV different from a credit bureau SSN check?
Bureau checks compare against compiled credit-header data, which synthetic identities deliberately seed and can pass. eCBSV checks against the SSA issuance record itself, which a fabricated identity cannot alter.
