Registration in DEERS

DEERS is a computerized database of military sponsors, families and others worldwide who are entitled under the law to TRICARE benefits. DEERS registration is required for TRICARE eligibility.

• Active-duty and retired service members are automatically registered in DEERS, but they must take action to register their family members and ensure they’re correctly entered into the database.
• Once registered in DEERS it is important to keep your DEERS records updated when personal eligibility information changes. This includes changes in military career status; addresses; and family status (marriage, divorce, birth, and adoption) etc. For basic information on eligibility, review our Eligibility Fact Sheet.
• Mistakes in the DEERS database can cause problems with TRICARE claims, so it is critical to maintain your DEERS information.
• Retail network pharmacies check TRICARE eligibility through DEERS. Prescriptions will be filled only for beneficiaries who are listed as eligible in DEERS.
• Each family member’s eligibility record must be updated separately when changes occur.
