CBSV Web Service
If you anticipate a large volume of verifications, web services may be your best choice.
The CBSV web service allows a business application to talk to and receive a response from our SSN verification service.
Although SSA cannot provide development support, we do provide a developer guide, a testing environment, and troubleshooting support. Review the CBSV Client Development Guide to determine what you will need to create a web service client.
