CBSV is a fee and consent-based Social Security number (SSN) verification service available to enrolled private companies and federal, state and local government agencies. It provides instant, automated verification and it easily handles large volume requests. Using CBSV, participating companies can verify the SSNs of their customers and clients. You must have an Employer Identification Number (EIN) to enroll..

CBSV verifies whether a name and Social Security Number (SSN) combination match the data in SSA’s records. The submitted information is matched against SSA’s Master File of Social Security Numbers (SSNs). The matching elements include: Social Security Number, name, date of birth and a gender code if available. Each SSN and name combination submitted to CBSV will be returned with a “yes” or “no” verification code indicating that the submission either matches or does not match our records. If applicable, we will report a death indicator when our records reflect that the SSN holder is deceased. Please note that the results obtained from CBSV do not confirm or authenticate "proof of identity”.

CBSV requires the written consent of the SSN holder and the verification results may only be used for the reason which the number holder specifies.

CBSV is fee-based. To use CBSV you must pay a one-time non-refundable enrollment fee of $5,000 and then pay a transaction fee per SSN verification request. The transaction fee is presently $1.05 and must be paid in advance.

Periodically, SSA will recalculate the costs it incurs in providing the CBSV service and will adjust the transaction fee charged. Subscribers will be notified in writing of any change in the transaction fee. SSA may close enrollment to CBSV at its discretion.
