Totalization Data Exchange (TDEX)

Published by Social Security Administration | Social Security Administration | Metadata Last Checked: August 09, 2025 | Last Modified: R/P1M
The Totalization Data Exchange (TDEX) process is an exchange between SSA and its foreign country partners to identify deaths of beneficiaries residing abroad. The process provides for the sharing of death data and restricts the disclosure of Personally Identifiable Information (PII). When TDEX was implemented in 2009 (TDEX II), it was comprised of two separate, distinct processes: one process provided death information to the Totalization (TOT) partners, the other process received death information from partner countries for use within SSA beginning in 2011. Enhancements were made to create a finder file process in which SSA sends information to our foreign partners concerning beneficiaries residing in their country. The foreign partners respond with death information for US beneficiaries who have died in their country.
