FALLS CHURCH, Va. – Do you or your family member expect to experience a qualifying life event, including planning to move this summer? If so, you’ll need to update your information in the Defense Enrollment Eligibility Reporting System (DEERS).

To remain eligible for TRICARE coverage, you must keep your information current. DEERS is a computerized database of active duty and retired service members, their family members and others who are eligible for TRICARE. Proper and current DEERS registration is key to getting timely, effective TRICARE benefits.

It’s essential to update and verify your information in DEERS anytime you have a qualifying life event. This is especially true during the summer moving season. After you arrive at a new duty station or location, update your information in DEERS. Your Social Security number and the number of each of your covered family members must be included in DEERS for your TRICARE coverage to be accurate.

You have several options for updating and verifying DEERS information. You can make changes in person, by phone, online or by mail.
