How to Schedule and Prepare for Your CAC ID Appointment

What happens at a CAC ID appointment and who needs one

A CAC ID appointment is where you get your Common Access Card — the military ID that lets you access base facilities, use military healthcare, and handle financial transactions on post. You need one if you are active duty, a reservist, a National Guard member, a dependent of military personnel, a retiree, or a Department of Defense civilian employee.

During the appointment, a RAPIDS technician will take your photograph, verify your identity documents, and issue your card on the spot or within a few days. The whole process usually takes 15 to 30 minutes, though wait times at busy locations can add an hour or more. You will walk out with either a physical card or a receipt showing your card is being mailed to you.

The card itself is valid for five years if you are active duty or a civilian employee, and ten years if you are a dependent or retiree. After that, you will need to renew it at another appointment.

Key Takeaways

• You must book your CAC ID appointment through your base's RAPIDS office or online portal — walk-ins are not accepted at most locations.
• Bring a current government-issued photo ID, your Social Security card or birth certificate, and proof of your military status or dependent relationship.
• If you are a dependent, bring the sponsor's military ID and a certified copy of your birth certificate or marriage certificate.
• Appointment slots fill quickly at large bases, so book as far in advance as your base allows — often 30 to 60 days out.

How to find and book your appointment

The RAPIDS office at your base handles CAC ID appointments. If you are stationed at a major installation, there is usually a dedicated RAPIDS office with its own phone line and online booking system. If you are at a smaller base or reserve center, RAPIDS services may be handled by the personnel office or security office.

Start by calling your base's main number and asking for RAPIDS or the ID card office. They will give you the phone number to call directly or a link to their online scheduling system. Some bases use MilitaryOneSource or their own internal portal; others still take appointments by phone. Ask which method your base uses before you hang up.

Online systems usually let you see available slots weeks in advance and book instantly. Phone lines are slower but can sometimes squeeze you in faster if you explain an urgent need. Either way, have your name, Social Security number, and military affiliation ready when you call or log in.

Documents you must bring

Bring a current government-issued photo ID — a driver's license, passport, or state ID card. You also need proof of your Social Security number: either your Social Security card itself or a birth certificate. If your birth certificate is not certified, bring it anyway along with the Social Security card.

Proof of military status depends on who you are. Active duty and reserve members should bring their military ID if they already have one, or their military orders. Civilians need their offer letter or employment verification. Dependents need the sponsor's military ID and a certified copy of their birth certificate (if under 21) or marriage certificate (if a spouse). Retirees need their military ID or retirement papers.

If any of your documents show a different name than you use now — because of marriage, divorce, or legal name change — bring the document that proves the change: a marriage certificate, divorce decree, or court order. RAPIDS will not process your card without it.

What to expect during the appointment

Arrive 10 minutes early. The technician will check your documents, ask you to confirm your personal information, and take a digital photograph. Wear something you would wear in a professional setting — no hats, sunglasses, or heavy makeup that obscures your face. The photo rules are strict because the card is a federal ID.

The technician will then swipe your documents into the system, verify your military status in the Defense Enrollment may be able to access Reporting System (DEERS), and print or order your card. If everything matches and there are no flags in your background, you will either leave with the card in hand or receive a receipt with a tracking number showing when it will arrive by mail.

The whole appointment takes 15 to 30 minutes if the office is not backed up. If there is a delay in DEERS or a discrepancy in your paperwork, the technician will tell you what needs to be fixed and whether you need to come back or if they can resolve it on the spot.

If your appointment gets delayed or cancelled

RAPIDS offices sometimes cancel appointments without warning because of staffing shortages, system outages, or base-wide closures. If your appointment is cancelled, the office will usually call or email you. Check your email and voicemail regularly in the days before your appointment.

If you miss your appointment, call RAPIDS immediately to reschedule. Most bases will rebook you within a week or two, but during peak times — summer, holiday season, or after a base-wide ID expiration notice — the wait can stretch to several weeks. If you have an urgent need, explain it when you reschedule; some offices keep a small number of same-day or next-day slots for military moves or deployments.

If your appointment is delayed because of a document problem, ask the technician exactly what is missing or incorrect. Do not leave without knowing whether you can fix it by mail, email, or in person before your next visit.

Renewing or replacing your CAC ID

When your card is about to expire, you will receive a notice from your base's RAPIDS office. Schedule a renewal appointment the same way you booked your first one — through the online system or by phone. Bring the same documents you brought the first time, plus your expiring CAC ID.

If your card is lost, stolen, or damaged, call RAPIDS right away. You will need to schedule an appointment to get a replacement. Bring a police report if the card was stolen; RAPIDS may ask for it. Replacement cards usually cost nothing for active duty and dependents, but some bases charge a small fee for civilians or retirees — ask when you call.

Frequently Asked Questions

Can I get a CAC ID appointment if I do not live near a military base?

Some bases offer appointments to people stationed overseas or in remote locations through mail-in processes or regional RAPIDS offices. Call your sponsor's base RAPIDS office and explain your situation. They may be able to direct you to the nearest office that serves your area or provide instructions for mailing documents.

What if I do not have a birth certificate or Social Security card?

You can order a birth certificate from your state's vital records office — it usually takes one to two weeks. A replacement Social Security card can be ordered online through ssa.gov or at your local Social Security office. Do not schedule your RAPIDS appointment until you have at least one of these documents in hand.

Do I need to bring my dependent child to the appointment?

Yes, dependents under 18 must be present for their own CAC ID appointment. Bring the sponsor's military ID and the child's certified birth certificate. If the child is 18 or older, they can go alone with their own government ID and birth certificate, though having the sponsor present can speed things up.

How long does it take to get the card if it is mailed?

If the technician mails your card, it usually arrives within five to ten business days. You will receive a receipt with a tracking number. If it does not arrive within two weeks, call RAPIDS with your receipt number and they can check the status or reissue it.

Can I use a digital copy of my documents instead of originals?

No. RAPIDS requires original documents or certified copies. A certified copy means a document stamped and signed by the issuing office — not a photocopy you made yourself. If you do not have originals, order certified copies before your appointment.
