Lesson 1: DEERS and your ID card

About 15 minutes, plus 15 minutes for your action step

Professor Hoot, the BMU owl, thinking

Warm up

1. Think of a time you started a new job or moved to a new town. What did you need to do first?

See the answer

Military life has a first step too. It is DEERS.

Why this matters

You married a service member. Welcome. Your benefits, like health care and base access, start with one record. It is called DEERS.

TRICARE says you must be in DEERS to get your TRICARE benefit. This free course walks you through your first 90 days, one step at a time. BMU 302 Military Spouse Field Manual goes deeper later.

Start with what you already do

You already keep important papers, like a birth certificate or a Social Security card, in a safe place.

Common belief: Getting married adds me to the military system on its own.

What is actually true: Not so. The service member, called your sponsor, must register you in DEERS. Sponsors are added on their own. Family members are not.

In this lesson you will

  • Explain what DEERS is and who registers you
  • List the papers to bring to the ID card office
  • Book an ID card office visit

Key words

sponsor
The service member whose benefits you get as a family member.
DEERS
The Defense Enrollment Eligibility Reporting System. It is the list of people who can get military benefits.
RAPIDS site
An ID card office. This is where you get your ID card.

Step 1: Your sponsor registers you

Your sponsor must register you in DEERS. The form is DD Form 1172-2. TRICARE's page calls it DD Form 1172.

milConnect asks sponsors to register a marriage within 30 days to avoid pay deductions later.

Step 2: Bring the right papers

TRICARE says these must be originals or certified copies. For the ID card itself, bring two IDs that are not expired. One must be a state or federal photo ID, like a driver's license or passport.

Step 3: Book a visit

Use ID Card Office Online to find a RAPIDS site and book a time. Call the office first if you have questions. Expect to have your picture taken.

Keep DEERS correct

TRICARE says errors in DEERS cause problems with claims, bills, and prescriptions. Update it after any change, like a move or a new phone number. You can check it in ID Card Office Online or call 800 538 9552.

Worked example: Rosa and Dan

Rosa married Dan, a Marine, last week.

  1. Dan books a time at the base ID card office online.
  2. Rosa gathers the original marriage certificate, her birth certificate, her Social Security card, and her driver's license.
  3. She adds her passport as her second ID.
  4. They go together. Dan signs the form. Rosa gets her picture taken and leaves with her ID card.

Rosa and Dan are a made up example.

Practice: Plan the ID card visit

  • Kim married a soldier who leaves for a 9 month deployment next week.
  • Joe married a sailor. They live 3 hours from a base, and Joe has only a photocopy of his birth certificate.

For each person, write what to do so the visit works the first time.

Check your practice: feedback
  • Kim: before he leaves, her sponsor signs DD Form 1172-2, electronically or in front of a notary, or gives her a power of attorney. The signature must be recent, within 90 days of her visit.
  • Joe: order a certified copy of his birth certificate from the state where he was born. Then book a RAPIDS site online and call ahead, since the drive is long.

Common mistakes

Try it: Start your who to call sheet

Pick your scenario:

  • We are near a base
  • We are far from a base
  • My sponsor is away right now

Support level: full. Use the three steps as your list.

  1. Write your sponsor's name and branch.
  2. Check off each paper you have.
  3. Find the nearest RAPIDS site in ID Card Office Online.
  4. Write the office phone number.
  5. Write the date of your visit.

Do it by: today

Reflect

Which paper will be hardest to find? Who can help you get it?
