SSN Verification Service

Published by Social Security Administration | Social Security Administration | Metadata Last Checked: August 09, 2025 | Last Modified: R/P1D
The SSN Verification Service is used by Java applications to execute the GUVERF02 service using the WebSphere/CICS Interface. It accepts several input data fields like First Name, Last Name, and Mother's Maiden Name and compares the data to the corresponding fields on the Numident record. SSN Verify Service can be invoked from WebSphere only through the CMM infrastructure. The Numident record is retrieved by calling the GUNSCHIP general utility. This service is currently being used by the appointment application to match input data with the information on the Numident.
