DEERS enrollment for TRICARE happens in person at a military ID card office, where a Verifying Official reviews the sponsor’s paperwork, checks each family member’s supporting documents, enters the information into the Real-Time Automated Personnel Identification System, and issues a Uniformed Services ID card. Coverage becomes active the moment that record is created. The sponsor, meaning the service member, retiree, or activated Guard or Reserve member whose service creates the benefit, is usually already in the Defense Enrollment Eligibility Reporting System automatically. Everyone else in the family has to be added by the sponsor.1eCFR. 32 CFR 199.3 – Eligibility
Who Can Be Enrolled
Federal law draws the eligibility lines narrowly. If a family member does not fit one of the defined categories, they cannot be added to DEERS, and no closeness of relationship changes that.2Office of the Law Revision Counsel. 10 USC 1072 – Definitions
The dependents who qualify:
- A current legal spouse of the sponsor.
- Unmarried children under 21. This includes biological children, adopted children, stepchildren, and children under legal guardianship.
- Unmarried children up to age 23 who are enrolled full-time at an approved institution of higher learning, provided the sponsor supplies more than 50 percent of their financial support.1eCFR. 32 CFR 199.3 – Eligibility
- Unmarried children of any age with a mental or physical disability that prevents self-support, if the condition existed before age 21 (or before age 23 for a child who was a full-time student when the disability began). Eligibility continues as long as the condition persists and the child remains unmarried.
Sponsors themselves include active duty service members, military retirees, and Guard or Reserve members called to active duty for more than 30 consecutive days.
Documents to Bring
DEERS requires original documents or copies certified by the issuing government agency. Notarized photocopies generally will not be accepted, so gather the originals before scheduling the appointment.
- Social Security cards for the sponsor and every family member being enrolled.
- Birth certificates for all children.
- A government-issued marriage certificate to add a spouse.
- Final divorce decrees for any prior marriages of the sponsor or spouse.
- Court-issued adoption or guardianship papers for any child who is not the sponsor’s biological offspring.
- DD Form 1172-2, the Application for Identification Card/DEERS Enrollment, filled out ahead of time. It is available through the DoD forms website and at ID card offices.3Department of Defense. DD Form 1172-2 – Application for Identification Card/DEERS Enrollment4Washington Headquarters Services. DD Form 1172-2 – Application for Identification Cards/DEERS Enrollment
Both the sponsor and each dependent being enrolled need to bring two forms of valid identification, with at least one bearing a current photograph, such as a driver’s license or passport.
Stepchildren
Adding a stepchild takes the child’s birth certificate, the child’s Social Security card, and the sponsor’s marriage certificate to the child’s biological parent. That marriage certificate is what establishes the stepparent relationship on the record.5TRICARE. Required Documents
Foreign Documents
Birth and marriage certificates issued by a foreign government must carry either an apostille from the issuing country’s authority or a Certificate of Authentication from a U.S. Consular Officer in that country. Documents in a language other than English also need an English translation.6Department of Defense. DoD Identity and Eligibility Documentation Requirements Certifications from countries with limited U.S. consular presence can take weeks or months, so start early.
Adult Children with a Qualifying Disability
Enrolling a disabled child past age 21 requires a current physician’s statement documenting the condition. It typically must be dated within 90 days of the application and endorsed by a military treatment facility. Eligibility has to be re-established each time the dependent’s ID card expires, which means the medical documentation is not a one-time task.
How the Appointment Works
DEERS records are processed through RAPIDS terminals at ID card offices on military installations, National Guard facilities, and some reserve centers. Find the closest office and book a slot through the ID Card Office Online portal.7ID Card Office Online. ID Card Office Online Walk-ins are sometimes accepted, but appointments are strongly recommended because wait times at busy installations can run for hours.
At the appointment, the Verifying Official reviews DD Form 1172-2 and the supporting documents. Once everything checks out, the official enters the data into RAPIDS and prints the Uniformed Services ID card for the new beneficiary. TRICARE eligibility becomes active immediately.
If the Sponsor Cannot Be Present
Deployments, remote assignments, and temporary duty can put the sponsor out of reach on appointment day. A family member can still complete DEERS updates alone with either a DD Form 1172-2 signed by the sponsor within the previous 90 days or a valid power of attorney.5TRICARE. Required Documents A general power of attorney is not always accepted, so a specific power of attorney authorizing DEERS transactions is the safer document to carry.
Situations at the Edges of Eligibility
Former Spouses
A divorce does not automatically end TRICARE coverage. Two federal rules govern what continues, and both depend on the length of the marriage and its overlap with the sponsor’s creditable service.
Under the 20/20/20 rule, a former spouse keeps full TRICARE eligibility with the same benefits as a retired family member if the sponsor has at least 20 years of creditable service, the marriage lasted at least 20 years, and all 20 years of the marriage overlapped with those 20 years of service. Coverage continues indefinitely unless the former spouse remarries before age 55 or becomes eligible for an employer-sponsored health plan.8TRICARE. Former Spouses
The 20/20/15 rule applies when marriage and service each reach 20 years, but only 15 years overlap. For divorces finalized on or after September 29, 1988, this produces only one year of TRICARE eligibility from the date of divorce.1eCFR. 32 CFR 199.3 – Eligibility The window is non-renewable, so alternative coverage needs to be in place before it closes.
Children Over 21
Standard TRICARE eligibility ends at 21, or at 23 for a full-time student. TRICARE Young Adult (TYA) is a premium-based plan that extends coverage for unmarried adult children up to age 26.9TRICARE. TRICARE Young Adult10GovInfo. 10 USC 1110b – TRICARE Young Adult The adult child cannot be eligible for an employer-sponsored health plan through their own job. If their employer offers coverage, they are disqualified from TYA even if they have not enrolled in it. The child must still be registered in DEERS. Premiums for 2026 run $794 per month for TYA Prime and $363 per month for TYA Select and are paid entirely by the family.11TRICARE. TRICARE 2026 Costs and Fees Preview
Turning 65
When a TRICARE beneficiary turns 65, standard TRICARE does not simply continue. To keep receiving benefits, the beneficiary must enroll in both Medicare Part A and Part B. Once both are active, TRICARE For Life takes over automatically as a Medicare supplement.12TRICARE. TRICARE For Life Part B carries a monthly premium of $202.90 in 2026.13CMS. 2026 Medicare Parts A and B Premiums and Deductibles Skipping Part B ends TRICARE coverage entirely once Medicare eligibility begins. Missing the initial enrollment window also triggers a late-enrollment penalty of 10 percent added to the Part B premium for every full 12-month period the person could have had Part B but did not, and that penalty is permanent.14TRICARE. Beneficiaries Eligible for TRICARE and Medicare Spouses of active duty sponsors can delay Part B without penalty; everyone else needs to enroll on time.
After a Sponsor’s Death
Survivors do not need to rush an in-person visit to report a sponsor’s death. The Defense Manpower Data Center receives notification automatically from the military services and the Social Security Administration, and DEERS updates from there. To speed things up, survivors can bring a death certificate to a local ID card office or fax it to DMDC.15TRICARE. Survivors16TRICARE. Survivors of Active Duty Service Members17Office of the Law Revision Counsel. 10 USC 1079 – Contracts for Medical Care for Spouses and Children
Keeping the Record Current
An outdated DEERS record can block a claim, delay a prescription, or cause a provider to turn a family member away at check-in. Addresses, phone numbers, and email addresses tied to the TRICARE account can be verified and updated through the milConnect portal at milconnect.dmdc.osd.mil. Adding or removing a family member still requires an in-person ID card office visit with supporting documents; the online tools handle contact information, not who is covered.
Qualifying Life Events
Certain life changes open a 90-day window to adjust TRICARE enrollment: the birth or adoption of a child, marriage, divorce, a sponsor’s retirement from active duty, or a dependent aging out of coverage.18TRICARE. Qualifying Life Events The clock starts on the event date, not the date you get to it. A retiring service member who does not enroll in a plan within 90 days loses coverage entirely and can then only receive care at military hospitals or clinics on a space-available basis. Family members who miss their window face the same space-available limitation until the next qualifying life event or Open Season.19TRICARE. TRICARE Qualifying Life Events Fact Sheet
Open Season
Each fall, TRICARE holds an Open Season for eligible beneficiaries to enroll, switch plans, or change between individual and family enrollment. Changes take effect January 1 of the following year.20TRICARE. TRICARE Open Season Anyone satisfied with the current plan does not need to act.
When DEERS Says You Are Ineligible
Eligibility is set by the military services through DEERS, not by TRICARE’s claims contractors. A record that shows a beneficiary as ineligible has to be corrected through the sponsor’s specific service branch personnel office. TRICARE’s formal appeals process handles claims decisions, such as coverage denials and payment disputes, but not eligibility determinations. If the dispute is about whether someone qualifies at all, the service branch is the only office that can fix it.
