How to Schedule and Complete Your DoD CAC Card Appointment

What happens at a CAC appointment and where to book one

A CAC (Common Access Card) appointment is where you get your military ID card issued or renewed. The appointment itself takes 15 to 30 minutes — you'll have your photo taken, provide your fingerprints, and sign documents. The card is printed on-site or mailed to you within a few days, depending on your installation.

You book through your military branch's ID card office, which is usually located at a base, reserve center, or National Guard armory. Some installations let you book online through their scheduling system; others require you to call. The office that handles this is often called the ID Card Section, Real ID Office, or RAPIDS office (the system that prints the cards). Start by searching "[your base name] ID card appointment" or calling your base's main number and asking for the ID card office directly.

Wait times vary widely. Some installations have same-day or next-day slots; others have a weeks-long backlog. If you're active duty, reserve, or National Guard, your branch's ID card office is your first call. If you're a dependent or retiree, you'll use the same office but may have different hours or appointment availability.

Key Takeaways

• Book your CAC appointment through your military installation's ID Card Section or RAPIDS office, either online or by phone — the method depends on which base you use.
• Bring a valid photo ID, your Social Security card or birth certificate, and proof of your military status (orders, military ID, or dependent ID card).
• The appointment itself takes 15 to 30 minutes for photos and fingerprints, but the card may take several days to arrive by mail.
• If your installation's system is full, ask when the next opening is and whether you can book at a different nearby base or reserve center.
• Bring all required documents to your first appointment — going back for missing paperwork adds weeks to the process.

Documents you need to bring

Bring originals, not copies. The ID card office will not accept photocopies of most documents. You'll need a valid photo ID (driver's license, passport, or current military ID) and proof of your Social Security number or citizenship. A Social Security card works, but so does a birth certificate, passport, or naturalization papers.

You also need proof of your military status. If you're active duty, your military ID or orders will do. If you're reserve or National Guard, bring your military ID or your most recent orders. If you're a dependent, bring the sponsor's military ID and your dependent ID card if you have one. If you're a retiree, bring your retiree card or your discharge papers.

Some installations ask for additional documents depending on your situation — for example, a marriage certificate if your name has changed, or a court order if you're updating your legal name. Call the ID card office before your appointment and ask what they need for your specific status. Missing a single document often means rescheduling.

How to find your installation's booking system

The easiest route is to go to your branch's official website and search for "ID card appointment" or "RAPIDS scheduling." The Army, Navy, Air Force, Marines, and Coast Guard each run their own systems. If your installation has an online portal, you can usually book a slot immediately and see available times for the next few weeks.

If there's no online system or it's full, call the base's main switchboard and ask for the ID Card Section or RAPIDS office. Have your military ID number or Social Security number ready. Ask them directly: "When is the next available appointment?" and "Can I book at another installation if this one is full?" Many regions have multiple bases or reserve centers, and some allow you to use any of them.

If you're a dependent or retiree and your sponsor is active duty at a base far away, you may be able to use the ID card office at a closer installation. Ask whether you can transfer your appointment or book locally. Some bases prioritize active-duty personnel and may have longer waits for dependents, so knowing your options ahead of time saves frustration.

What to expect on the day of your appointment

Arrive 10 to 15 minutes early with all your documents in a folder. The office will verify your identity, check your military status, and confirm your information is correct in the system. They'll take a digital photo — wear something you'd wear to work, avoid hats and sunglasses, and make sure your face is clearly visible.

Next, you'll provide your fingerprints. This is done electronically, usually on a small scanner. The staff will guide you through it. You'll then sign several documents, including a statement that your information is correct and a form authorizing the card to be issued. The whole process is straightforward; the office staff do this hundreds of times a week.

Ask before you leave whether your card will be mailed to you or printed on-site. If it's mailed, ask for a tracking number or expected delivery date. If it's printed there, you may get it the same day or within a few days. Some installations give you a temporary paper ID if your card will take longer to arrive.

If your appointment gets cancelled or the office is closed

Military ID card offices sometimes close for training, staffing shortages, or facility maintenance. If you call and the office is closed, ask when it will reopen and whether you can book an appointment for that date. If the office is closed for more than a week, ask whether you can use a different installation in your region.

If your appointment is cancelled by the office, they'll usually call or email you. Reschedule as soon as you can — some installations fill up weeks in advance. If you need your CAC urgently (for base access, travel, or work), explain that to the office staff when you reschedule. Some offices have expedited slots for people with immediate needs.

If you're stationed overseas or in a remote location, contact your base's personnel office or your unit's administrative staff. They can tell you whether the ID card office is on-site or whether you need to travel to another location. Some overseas bases have limited hours or require advance notice.

Renewing or replacing a CAC that's expired or damaged

A CAC is valid for five years from the date it's issued. When it's close to expiring, you'll need to schedule a renewal appointment using the same process — call or book online through your installation's ID card office. Bring the same documents as you would for a new card.

If your card is lost, stolen, or damaged, report it to your installation's security office or ID card office right away. You'll need to fill out a report and then schedule a replacement appointment. Bring your report number and the same documents as for a renewal. Replacement cards usually take the same amount of time as new cards.

Frequently Asked Questions

Can I book a CAC appointment online, or do I have to call?

It depends on your installation. Many bases have online scheduling systems where you can see available times and book immediately. Others require you to call. Start by searching your base's name plus "ID card appointment" or "RAPIDS scheduling" to see if an online system exists. If not, call the base's main number and ask for the ID Card Section.

What if I don't have my Social Security card?

A birth certificate, passport, or naturalization papers will work instead. The office needs proof of your Social Security number or citizenship; they don't require the card itself. Call ahead and tell them which document you're bringing so they know to expect it.

How long does it take to get my CAC after the appointment?

If the card is printed on-site, you may get it the same day or within a few days. If it's mailed, it usually arrives within one to two weeks. Ask the office staff before you leave which method they're using and whether they can give you a tracking number or expected date.

Can I book a CAC appointment at a base other than where I'm stationed?

Many installations allow this, especially if you're a dependent or retiree using a closer base. Call your home installation's ID card office and ask whether you can book at another location. Some bases have reciprocal agreements; others require you to use your assigned installation.

What if I miss my appointment?

Call the ID card office as soon as you realize you've missed it. Explain what happened and ask to reschedule. Most offices will rebook you, though you may have to wait for the next available slot. If you're going to be late, call ahead — some offices can hold your appointment for 15 to 30 minutes.
