State Verification and Exchange System

Overview
The State Verification and Exchange System (SVES) provides verification of Social Security numbers and benefits information used to establish eligibility for income and health maintenance programs. The system allows users to request data from other SSA data exchange applications. In these cases, SVES filters the requesting transactions to determine the appropriate applications for processing. SVES then passes the requests to the applications, which process the requests and return responses to the partners.
