DEERS(DEFENSE ENROLLMENT ELEGIBILITY REPORTYING SYSTEM)
DEERS is a worldwide, computerized database of uniformed services members (sponsors), their family members, and others who are eligible for military benefits, including TRICARE. All sponsors are automatically registered in DEERS.
The sponsor has to register all eligible family members. No one can add or delete a family member from DEERS, besides the sponsor. The sponsor is the only person that can make changes like this. Once family is enrolled they can update their own personal information, such as address and phone numbers. You have to be enrolled in DEERS to set up your tricare benefits, obtain a DOD Dependant Identification Card, apply for military housing, etc. You can update Tricare information by clicking HERE
