Understanding DEERS and the CAC Card System
DEERS stands for Defense Enrollment Eligibility Reporting System. This is the military's database that tracks information about service members, veterans, retirees, and their family members. The Department of Defense maintains DEERS to verify who is part of the military community and what benefits they may access.

A CAC card is a Common Access Card. This is a physical identification card that the military issues to active duty service members, reserve and National Guard personnel, retirees, and certain civilian employees. The CAC card serves as both a military ID and a security credential. It allows holders to access military facilities, use military computers and networks, and prove their status as part of the military system.
Your DEERS record and CAC card work together. The information stored in DEERS determines who can receive a CAC card. When you need a new CAC card, are renewing an existing one, or need to update your information, the military office handling your request will check your DEERS record to confirm your status. This verification process ensures that only people who are truly authorized receive CAC cards.
The DEERS database contains personal information such as your name, Social Security number, date of birth, military status (active duty, retired, veteran, family member), and details about any dependents. This information affects whether you can schedule an appointment to obtain or renew a CAC card. Understanding how DEERS works helps explain why military ID offices ask for specific information during the appointment scheduling process.
Practical takeaway: Before scheduling a CAC card appointment, understand that the military will verify your information through DEERS. Having your Social Security number and military status information ready will speed up the appointment scheduling process.
How CAC Card Appointment Scheduling Works
Scheduling a CAC card appointment involves several steps that vary slightly depending on your military status and which military branch or location you work with. The general process begins by finding the right office or facility near you that issues CAC cards. Different branches of the military and different installations may use different scheduling systems, so locating the correct office is your first step.

Most military installations have an ID card office or personnel security office that handles CAC card issuance and renewal. These offices are typically located on military bases, though some locations may offer services at nearby military facilities or administrative centers. To find the office that serves you, you can search online using your military branch name plus "ID card office" and your geographic location.
Once you locate the correct office, you have several options for scheduling. Many installations now offer online scheduling systems where you can select a date and time that works for you. Some offices still require you to call during business hours to schedule an appointment. A smaller number of locations may allow walk-in appointments, though having a scheduled time is increasingly standard.
When you contact the office or use their online system, be ready to provide certain information. This typically includes your name, Social Security number, military status or service number, and your current contact information. The staff member handling your scheduling may also ask about the purpose of your visit—whether you are getting a new card, renewing an existing one, or updating information.
Appointment times are usually available during regular business hours on weekdays. Some installations may offer limited evening or weekend hours. The actual appointment typically takes 15 to 45 minutes, depending on whether your information is current in the system or whether additional verification is needed.
Practical takeaway: Start by identifying which military ID card office serves your location. Then determine whether that office uses online scheduling, phone scheduling, or walk-in service. Having your military identification number or Social Security number ready will speed up the scheduling conversation.
Documents and Information to Prepare Before Your Appointment
Preparing the right documents before your appointment saves time and reduces the chance that your appointment will need to be rescheduled. The military ID card office will ask you to bring specific items when you arrive for your appointment. While requirements can vary slightly between installations and military branches, certain items are standard across nearly all locations.

Your current military ID card or another government-issued photo ID is typically required. If you are renewing an existing CAC card, bringing the old card helps the staff locate your file and verify your information. If this is your first CAC card, a passport, driver's license, or state ID will work as your photo identification. The photo ID must be current or expired within a reasonable timeframe—usually no more than five years.
Proof of birth date is often required. A birth certificate, passport, or driver's license typically satisfies this requirement. The document must be an official record, not a photocopy you made yourself. If your birth certificate is not readily available, a passport works in its place since it also contains your birth date and is an official government document.
Proof of citizenship or status is another requirement. U.S. citizens should bring a passport, birth certificate, or naturalization papers. If you are a citizen of another country with military status (for example, if you are a permanent resident serving in the military), you will need to bring documentation showing your immigration status and authorization to work in the United States.
Social Security verification may be requested. Your Social Security card itself is not usually required, but the ID office may ask you to verify your number verbally. If you do not know your Social Security number by heart, bring a document that displays it—such as a tax return, W-2 form, or Social Security statement.
For dependents of military members, additional documentation may be needed. This could include a marriage certificate if the dependent spouse is receiving their card for the first time, or a birth certificate for dependent children. Dependent parents or parents-in-law may need to provide documentation of their relationship to the service member.
Bring any recent address changes or status changes with you. If you have moved since your last ID card issuance, have your new address ready. If your military status has changed (for example, moving from active duty to reserve status), documentation supporting this change helps the office update your DEERS record correctly.
Practical takeaway: Create a checklist two days before your appointment including your photo ID, proof of birth date, citizenship documentation, and any paperwork related to recent status changes. Having these items organized and ready to present will make your appointment move more smoothly.
Finding Your Local Military ID Card Office
Locating the military ID card office that serves your area is essential before you can schedule an appointment. The process differs slightly depending on your military status and which branch of the military you are connected to. Service members and retirees stationed at a military base will use the ID card office on their installation. Those not at a base must locate a nearby facility that provides CAC card services.

The Department of Defense maintains a directory of RAPIDS (Real-time Automated Personnel Identification System) locations where you can obtain a CAC card. RAPIDS is the official system that military installations use to issue CAC cards. Searching the RAPIDS website by your state or ZIP code shows all locations near you that issue CAC cards. The RAPIDS website also displays the hours of operation and phone numbers for each location.
Another way to locate an ID card office is through your military branch's official website. The Army, Navy, Air Force, Marine Corps, Coast Guard, and Space Force each maintain information about ID card services for their personnel. These websites typically have a section for ID cards or personnel services that includes a locator tool or directory.
If you are a military family member or retiree not currently stationed at a base, you may be able to use an ID card office at any nearby military installation. Some locations also have satellite ID card offices in civilian areas near military bases. Calling the main installation's customer service line and asking for the location of the nearest ID card office is another straightforward approach.
The Veterans Health Administration (VHA) also partners with some military installations to issue CAC cards to eligible veterans. If you are a veteran and not currently stationed anywhere, checking with your nearest VA facility may reveal that they can issue or renew your CAC card, or they can direct you to the nearest military facility that handles this service.
When you contact an ID card office, have your military status information ready. The staff member can then tell you whether you should schedule at that location or be directed to a different facility based on your specific situation. Hours of operation vary by location, but most military ID card offices operate during standard business hours, Monday through Friday.
Practical takeaway: Visit the RAPIDS website or your military branch's official website to locate the ID
