Uniformed Services ID Card (USID)
The DoD-issued ID card that proves uniformed services affiliation — required (with DEERS) to access military health benefits.
Also known as: military ID, retiree ID card, USID, Next Generation USID
Quick answer
The Uniformed Services ID (USID) card — currently issued as the Next Generation USID — proves your status as a retiree, family member, or other eligible beneficiary. Cards are issued by RAPIDS sites and tied to your DEERS record. The new Next Generation USID no longer has a printed expiration for many retiree categories (they are issued indefinitely under current rules).
Why it matters
MTF access, on-base privileges, and many in-person TRICARE/TFL service interactions require a valid USID. Even though TFL claims are processed electronically by WPS, providers and pharmacies may ask to see a current ID.
Why this matters at age 65
If your spouse has an expiring USID near age 65, renew it before Medicare enrollment — an expired card can complicate DEERS verification and TFL eligibility checks at providers.
When you'll encounter it
ID expiration, dependent enrollment, address change, name change, lost card.
Impact on Medicare
None — Medicare uses its own red-white-blue card.
Impact on TRICARE For Life
TFL claims processing is electronic and does not require an ID at the time of service, but providers may request it for verification.
Military-specific context
Cards are issued at RAPIDS sites (most installations and some federal facilities). Schedule appointments at idco.dmdc.osd.mil/idco/. Bring two forms of ID per the RAPIDS requirements.
Common misconceptions
- "An expired USID terminates TFL." — TFL is based on DEERS plus Medicare A and B — not the physical card. But keep the card current to avoid friction at providers and on-base.
Common mistakes to avoid
- Letting a spouse's USID expire and discovering it at a pharmacy or MTF.
- Not updating the address on the USID/DEERS record after a move.

- Can I still use the MTF pharmacy after 65?Yes. MTF pharmacies remain available to TFL beneficiaries with no copay, subject to local capacity. This is usually the cheapest pharmacy option.
- Can I go to urgent care on TFL?Yes. Use any Medicare-participating urgent care clinic. Medicare pays first, TFL pays second, and you almost always owe nothing beyond a small copay.
- What actually changes the day I turn 65?Your TRICARE Prime/Select ends, Medicare A and B become primary, TRICARE For Life turns on as your secondary, and your MTF access drops to space-available.
- Do I get a new TRICARE For Life card?No. There's no separate TFL card. Your uniformed services ID card and your red-white-and-blue Medicare card are your proof of coverage.
