Beneficiaries may update their DEERS address, telephone number, and e-mail data in various ways:

• Visit the DEERS Web site — this is the quick and easy way to update your information. The best time to update is during non-peak hours!
• Visit a local personnel office that has a uniformed services ID card facility. To locate the nearest ID card facility, visit DMDC's Rapid site locator. Call ahead for hours of operation and for instructions if you are updating a record for someone who is housebound.
• Fax address changes to 1-301-713-4140.
• Mail the changed information to the CPC, ATTN: DEERS UPDATE, 1315 East West Highway, Silver Spring, Maryland 20910-3282.

Updating Information other than Addresses:

Beneficiaries will need to provide important pieces of documentation, such as marriage, birth, or death certificates; DD 214s; DD 1172s; etc. Beneficiaries should contact the nearest Uniformed Services ID card facility to find out what documents they need to enroll or update eligibility information in DEERS. Once beneficiaries have the necessary documents, they can present them at the ID card facility.

Remember: TRICARE does not determine eligibility:

All eligibility information is determined by the Uniformed Services and recorded in DEERS. It is your responsibility to make sure personal information is correctly maintained and updated in DEERS in order to continue to be covered by TRICARE benefits.
