The Internet Claims application (formerly known as Ready Retirement and the Internet Social Security Benefit Application (ISBA)) allows claimants to complete and submit applications for retirement, disability and aged spouse's benefits via the Internet. A part of the i-Claims processing includes establishing proof of age and proof of citizenship for applicants using SSA's main data stores (ICD, MBR, SSR and NUMIDENT). VSB is responsible for the NUMIDENT Utility Subprogram which compares the information submitted by the application to the data stored on the NUMIDENT to establish POA and POC. The utility also applies a tolerance for analyzing several data fields on the NUMIDENT in conjunction with each other to further improve the likelihood of establishing eligibility.
