DEERS

The Defense Enrollment Eligibility Reporting System — the record that determines whether you and your family are eligible for TRICARE.

Applies to: All TRICARE plans · All regions

DEERS (Defense Enrollment Eligibility Reporting System) is the worldwide database of military sponsors, family members, and others entitled to military benefits. Being correctly registered in DEERS is what makes you eligible for TRICARE — if your information is outdated or a family member isn’t registered, claims and enrollment can be denied even when you’re otherwise eligible.

Sponsors are automatically registered. Family members must be separately registered by the sponsor at an ID card office, or updated online through milConnect.
