A person’s Defense Enrollment Eligibility Reporting System ID (DEERS ID) reflects his or her role within the military. Those roles may change, but attributes such as name, DOB, and SSN do not. A person can simultaneously hold multiple roles within the system, such as sponsor and family member. However, becoming a sponsor terminates eligibility as a family member. As a result, a person’s DEERS ID must be updated to reflect this change. This information is used by DoD to manage the process of awarding Public Key Infrastructure credentials and TRICARE eligibility. It is also used to identify individuals for other military and civilian benefits.
Service members, active-duty or retired, must be in DEERS to use TRICARE benefits. You can check your DEERS record on milConnect to ensure it is up to date and reflects any qualifying life events that may have occurred since you last updated your information. Incorrect information in DEERS can lead to delays with TRICARE applications and approval letters for referrals.

What is DEERS?
The Defense Enrollment Eligibility Reporting System is a veritable database of information about military members and their families. The information in DEERS is used to determine eligibility for various benefits, including healthcare coverage. Updating this information is essential for service members and their families, as incorrect DEERS information can lead to delays in claims processing and even a loss of benefits.
Every military member is automatically enrolled in DEERS upon joining the service. It is important to keep this information up to date as often as possible, especially if the servicemember and family are involved with TRICARE. Whenever a change occurs that affects a servicemember or their family, such as a name change, marriage, divorce, birth of a child, or retirement, it needs to be reported in DEERS right away so the appropriate changes can be made.
DEERS is a computerized database of military members, their spouses, and children that is used to verify eligibility for TRICARE and other benefits. It was implemented in 1982 and has spawned many follow-on programs, including RAPIDS and the National Enrollment Database. These follow-on programs have helped to improve the accuracy of information in the DEERS database, which helps ensure that TRICARE beneficiaries receive the benefits they are entitled to.

How to Update DEERS Info?
If you are looking to update your DEERS information, you can visit any RAPIDS office with two forms of identification. These documents can include a driver’s license, state ID, or social security card. The RAPIDS offices are located at most military bases and some reserve centers.
Updating your information in DEERS is important for several reasons, including ensuring that you have accurate contact information and preventing identity theft or fraud. It is also important to update your information if you move, so the proper records are updated with the correct address. Finally, if you want to apply for TRICARE, you must be registered in DEERS.
If your RAPIDS record isn’t current, you should bring a completed DA Form 4856 or Memorandum for Record to your personnel office as soon as possible. The DA form will be reported to the RAPIDS database, and your information will be updated.
When it comes to military health care, the information in DEERS is vital for determining eligibility for the program. The database is used to track a variety of things, from personal information and military status to medical history and family relationships. It is imperative that service members and their families stay up to date with their DEERS information, as a delay in updating can lead to a loss of TRICARE benefits. DEERS also provides an efficient way to communicate with one another in the event of a deployment or relocation. In addition, it is a great tool to help identify potential sources of fraudulent activity and support the mission of the Department of Defense. Hundreds of thousands of people in the military and their families worldwide use this massive, veritable database. It is a vital part of the military community.
