Unverified Prisoners System (UPS) - Data Exchange

Published by Social Security Administration | Social Security Administration | Catalog Last Checked: May 02, 2026 at 12:35 PM | Dataset Last Updated: March 22, 2019
UPS is an internal SSA system used by the Office of Earnings Operations (OEO) to track and resolve unverified prisoner and deportee records in an effort to find a match. Under federal law, individuals who are incarcerated or deported are not entitled or eligible to collect benefits under Social Security. In order to detect these individuals, prison facilities and Department of Homeland Security send SSA files containing the Names and SSNs of their inmate populations and deportees, respectively. The records are then verified through the Enumeration Verification System (EVS). Those that fail are processed through the Unverified Prisoner System where users manually attempt to match the prisoner and deportee records.
