How to update DEERS?

Keeping your DEERS (Defense Enrollment Eligibility Reporting System) information current is essential for maintaining TRICARE eligibility and benefits. There are several ways to update your DEERS records. Online through milConnect (milconnect.dmdc.osd.mil), you can update your address, phone number, email, and some dependent information after logging in with your DS Logon or CAC. In person at a RAPIDS ID card office, you can make all types of changes including adding or removing dependents, which requires supporting documentation. By phone, call the DEERS Support Office at 1-800-538-9552 (M-F, 7:30am-4:30pm ET) for assistance with address changes and general inquiries. By mail, send completed forms and supporting documents to the DEERS Support Office. Events requiring DEERS updates include marriage or divorce, birth or adoption of a child, death of a dependent, address or contact information changes, change in sponsor's military status, and Medicare enrollment. Failure to keep DEERS current can result in claims denials, loss of benefits, or inability to access care at military treatment facilities.
