DEERS enrollment is how the Department of Defense confirms that you and your family qualify for TRICARE, prescriptions, and base access. Active duty, retired, and Guard/Reserve members are added to the Defense Enrollment Eligibility Reporting System automatically when they enter service, but dependents are not. A spouse, child, or parent will not appear in the system until the sponsor takes affirmative steps to register them at an ID card office.1milConnect. DEERS Registration Eligibility and Enrollment Requirements
Getting the record right the first time matters. Inaccurate or missing information is one of the fastest ways to get a TRICARE claim denied or lose access to care.
Who Can Be Enrolled as a Dependent
Spouses
All lawful spouses should be registered in DEERS, even a spouse who has their own military record. Common-law spouses can qualify, but the sponsor has to produce a legal opinion from a Staff Judge Advocate confirming the marriage is recognized in the relevant jurisdiction, along with either a state-certified common-law marriage certificate or a court order establishing the marriage.2eCFR. 32 CFR Part 161 – Identification ID Cards for Members of the Uniformed Services, Their Dependents, and Other Eligible Individuals
Children
Unmarried children under 21 are eligible. That covers biological children, legally adopted children, stepchildren, and children whose paternity has been established by court order or voluntary acknowledgment.3Federal Register. 32 CFR Part 161 – Identification ID Cards for Members of the Uniformed Services, Their Dependents, and Other Eligible Individuals A child under 21 who marries and later divorces can have eligibility reinstated by presenting the divorce decree.2eCFR. 32 CFR Part 161 – Identification ID Cards for Members of the Uniformed Services, Their Dependents, and Other Eligible Individuals
A child between 21 and 23 can remain eligible if enrolled full-time at an approved institution of higher learning and the sponsor provides more than 50 percent of the child’s financial support. Children who cannot support themselves because of a mental or physical condition that began before age 21 (or before 23 while a full-time student) may qualify indefinitely, again on the more-than-50-percent support condition.3Federal Register. 32 CFR Part 161 – Identification ID Cards for Members of the Uniformed Services, Their Dependents, and Other Eligible Individuals That support threshold catches families off guard. A part-time job or a scholarship that pushes the sponsor’s share below half can end eligibility even while the child is still in school.
Parents and Parents-in-Law
A parent, parent-in-law, stepparent, or adoptive parent can be enrolled, but two conditions both have to be met: the parent must depend on the sponsor for more than 50 percent of their financial support, and the parent must live in the sponsor’s household.3Federal Register. 32 CFR Part 161 – Identification ID Cards for Members of the Uniformed Services, Their Dependents, and Other Eligible Individuals Proving it takes a separate application on DD Form 137-3, the Dependency Statement for Parents.
DD Form 137-3 asks for proof of support payments (allotments, bank transfers, canceled checks), verification of any income the parent receives (pay stubs, tax returns, Social Security letters), and an itemized breakdown of household and personal expenses. Cash payments and purchase receipts are not accepted. Every signature has to be notarized, or the form will be returned without action.4Defense Finance and Accounting Service.

Former Spouses
Divorce does not automatically end a former spouse’s benefits. Under the 20/20/20 rule, an unremarried former spouse keeps full TRICARE eligibility if the sponsor earned at least 20 years of creditable service toward retirement pay, the marriage lasted at least 20 years, and all 20 years of marriage overlapped with those 20 years of service. A qualifying former spouse becomes their own sponsor in DEERS under their own Social Security number.5TRICARE. Former Spouses
When the overlap is only 15 years (with 20 years of service and 20 years of marriage), the 20/20/15 rule gives the former spouse one year of continued TRICARE coverage after the divorce.6TRICARE Newsroom. How Divorce Affects Your Familys TRICARE Benefits Remarriage ends all health benefits and base privileges the day before the new marriage takes effect, and the former spouse has to surrender the military ID card.7milConnect. Life Events – Divorce
Surviving Spouses
Surviving spouses and dependent children of a service member or retiree generally remain eligible. Remarriage ends DoD benefit eligibility on the date of the new marriage. If the new spouse is a military sponsor, the surviving spouse can be added under that new sponsor’s record.8milConnect. FAQ – DEERS, TRICARE and DEERS
The Deadlines That Matter
A qualifying life event opens a 90-day window to update DEERS and make any related TRICARE enrollment changes. Marriage, birth, adoption, divorce, a PCS move, and Guard/Reserve activation or deactivation all count. Miss the window and you may be locked out of health plan changes until the next open season or the next qualifying event.9TRICARE. Qualifying Life Events
The order is always the same: update DEERS first. TRICARE enrollment changes cannot process until the underlying DEERS record reflects the new situation.
Newborns
Newborns have their own hard deadline. Stateside, register the child in DEERS within 90 days of birth, or TRICARE will deny every claim starting on day 91. Overseas, the deadline is 120 days, with denials starting on day 121.10TRICARE. Getting TRICARE for Your Child There is no automatic TRICARE coverage for a newborn before registration. Apply for the baby’s Social Security number right away and bring the card to an ID card office as soon as it arrives; milConnect advises adding a newborn within 30 days of birth, well before the claim cutoff.11milConnect. Newborn DEERS Registration
Divorce
Either the sponsor or the former spouse can report a divorce by taking the divorce decree to an ID card office, faxing it, or mailing it to the DEERS Support Office in Seaside, California. Delay creates a real financial risk: if a former spouse keeps getting care while ineligible, TRICARE will recoup every claim paid during that period.12TRICARE. How Do I Report My Divorce to TRICARE
Documents to Bring
Everyone appearing at an ID card office needs two unexpired forms of identification, and at least one has to be a government-issued photo ID. A U.S. passport, a state-issued driver’s license or ID card, a Permanent Resident Card (Form I-551), a foreign passport, an Employment Authorization Document (Form I-766), a military CAC, or a federal PIV card all qualify as primary photo ID.13TRICARE. Required Documents
All supporting documents (birth certificates, marriage certificates, adoption decrees) must be originals or certified copies. Photocopies get rejected.13TRICARE. Required Documents Certified copies come from state vital records offices, and fees usually run from about $10 to $35 per document. Some states take weeks, so request them early.
What you bring depends on who you are enrolling:
- Spouse: marriage certificate, spouse’s birth certificate, spouse’s Social Security card, and spouse’s photo ID.
- Biological child: birth certificate and Social Security card.
- Child born overseas: FS-240 Consular Report of Birth Abroad and Social Security card.
- Adopted child: record of adoption or letter of placement from a recognized agency or court, plus Social Security card.
- Stepchild: the child’s birth certificate, the marriage certificate connecting the sponsor to the child’s parent, and the child’s Social Security card.
- Parent or parent-in-law: a completed and notarized DD Form 137-3 with all financial documentation.4Defense Finance and Accounting Service. DD Form 137-3 Parents Dependency Statement Application Assistance
DD Form 1172-2 and Sponsor Signatures
DD Form 1172-2, “Application for Identification Cards/DEERS Enrollment,” is the core form for every enrollment action.14Washington Headquarters Services. DD Form 1172-2 – Application for Identification Cards DEERS Enrollment You can fill it out on paper or electronically through the ID Card Office Online portal. Sponsors who log in with a CAC or DS Logon can create, sign, and submit the form digitally without printing anything.15CAC.mil. Instructions for Completion of DD Form 1172-2
The sponsor has to sign to certify the information is truthful. There are four ways to do it:
- Electronic signature through IDCO using a CAC or DS Logon (no notarization needed).
- In person at the RAPIDS site, in front of the verifying official.
- A notarized wet signature on the paper form, which a family member then carries to the RAPIDS site.
- A valid power of attorney, if the sponsor is deployed or otherwise unavailable, allowing a family member to sign on the sponsor’s behalf.16CAC.mil. DoD Identity and Eligibility Documentation Requirements
When the sponsor is unavailable and a family member is handling enrollment, the signed DD Form 1172-2 has to have been signed within the previous 90 days, or the family member has to present a valid power of attorney.13TRICARE. Required Documents
Where to Go
Enrollment happens at a Real-time Automated Personnel Identification System (RAPIDS) site. Find one and book an appointment through the ID Card Office Online portal at idco.dmdc.osd.mil.17ID Card Office Online. ID Card Office Online Walk-ins are possible at some locations, but appointments fill quickly at larger installations, so book ahead.
At the visit, a technician reviews the original documents, scans them into the digital record, and takes a photograph for the ID card. Once verification is done, a Uniformed Services ID card is usually printed on the spot. The whole thing runs under an hour when the paperwork is in order.
People who live far from a RAPIDS site or are incapacitated may qualify for mail-in processing for certain updates, though this is more commonly available to retirees and remote dependents. Call the nearest ID card office to ask about remote processing if travel is a hardship.
Updating and Checking Your Record
Not every change requires a trip. Sponsors can update residential addresses, mailing addresses, and email addresses for themselves and family members through milConnect, using the Beneficiary Web Enrollment feature under the Contact Info tab.18milConnect. Updating Your Address in milConnect Keeping the address current is more important than it looks: TRICARE uses the DEERS address to determine which region you fall under and which providers are in network.
To verify what DEERS has on file, log in at milconnect.dmdc.osd.mil. You can view health care coverage, generate proof-of-coverage letters, and review eligibility correspondence for yourself and your family.19milConnect. milConnect – Manage Contact Information, Check Records and Benefits Corrections beyond contact updates, such as fixing an incorrect name or gender marker, go through your personnel office or the DMDC Customer Connect portal at mybenefits.mil/customerconnect. Adding or removing a family member still requires an in-person visit with original documents.
Check your DEERS record at least once a year and after every life event. A few minutes on milConnect can catch errors before they become denied claims.
