The US Social Security Administration (SSA) delivers social security services through a nationwide network of over 1,400 offices. The SSA offers the Consent Based Social Security Number Verification Service (CBSV) as a way of verifying whether a SSN holder's name and Social Security Number (SSN) combination match SSA's records. The CBSV can be used by companies offering banking and mortgage services, credit check processing, background checks and more.
The CBSV API can be used as an alternative to the online application. Users can access the functionality of the CBSV processing and can retreive results in real time. The API uses SOAP protocol and responses are formatted in XML.
