Understanding DEERS and CAC: What This Guide Covers
The Defense Enrollment Eligibility Reporting System, known as DEERS, is a database maintained by the Department of Defense. It tracks information about military service members, retirees, and their families. The Common Access Card, or CAC, is a physical identification card issued to active duty service members, Reserve and National Guard personnel, retirees, and their family members. This guide provides information about planning an appointment to obtain or renew a CAC through the DEERS system.

Understanding how DEERS and CAC work together is important for military-connected individuals. DEERS contains your personal and family information, including military status, Social Security number, date of birth, and dependent information. When you need a CAC, military personnel offices check DEERS to confirm your eligibility based on the information stored there. The CAC itself serves as a military identification and is also required for accessing military installations, receiving military medical care, and using various military benefits and services.
This informational guide walks through the steps of planning a CAC appointment. It explains what information you should gather before visiting, how to find the nearest issuing office, what documents to bring, and what to expect during your appointment. The guide also covers common reasons why appointments may need to be rescheduled and how DEERS records affect the appointment process.
According to the Department of Defense, there are approximately 17.6 million individuals in the DEERS database as of recent records. CACs are issued at thousands of locations worldwide, including military installations, reserve centers, and some state facilities. Having accurate DEERS information before your appointment can help the process move more smoothly.
Practical Takeaway: Before scheduling a CAC appointment, understand that DEERS contains your military records and that CAC issuance depends on accurate information in that system. Reviewing your DEERS data beforehand can prevent appointment delays.
Gathering Required Documents and Information Before Your Appointment
Preparing the right documents before your CAC appointment is one of the most important steps in the planning process. Different circumstances require different documents. For example, a service member applying for their first CAC will need different paperwork than someone renewing an expired card or a dependent family member obtaining their first CAC.

Generally, you will need to bring a valid government-issued photo identification. This might include a passport, driver's license, or state identification card. You should also bring your Social Security card or a document showing your Social Security number. For military service members, your military orders or a letter from your commanding officer may be needed. Dependent family members typically need to provide a marriage certificate, birth certificate, or adoption papers that establish their relationship to the sponsor.
The DEERS office recommends bringing originals of documents rather than copies whenever possible. If you have recently moved, changed your name, or updated your marital status, you should bring documentation of these changes. For example, if you were recently married, bring your marriage certificate. If you have recently divorced, bring a copy of the divorce decree. This helps ensure that your DEERS record is current and accurate before your CAC is issued.
You should also prepare a list of your personal information to verify during your appointment. This includes your full legal name, date of birth, Social Security number, current address, phone number, and email address. If any of this information has changed since you last updated DEERS, be ready to provide documentation of the change.
Family members should know their sponsor's Social Security number and military service information. Sponsors are the active duty, Reserve, National Guard, or retired service member through whom the family member is connected to the military. Having this information readily available will speed up your appointment.
Practical Takeaway: Create a checklist of required documents at least one week before your appointment. Gather originals of identification, Social Security documentation, and any recent life-change documents (marriage, divorce, birth certificates). Verify that your current address and contact information are accurate.
Locating CAC Issuance Offices and Scheduling Your Appointment
CAC cards are issued at numerous locations across the United States and at military installations worldwide. Finding the right office and scheduling an appointment requires knowing where these locations are and how to contact them. The Department of Defense maintains a locator tool online where you can search for CAC issuance offices by state, city, or installation name.

Active duty service members typically get their CACs issued at their duty station through their military personnel office. Reserve and National Guard members may have CACs issued at their unit location or at a regional military entrance processing station. Military retirees and their family members can often obtain CACs at nearby military installations, military entrance processing stations, or in some cases at state facilities that have been authorized to issue CACs.
The availability of appointments varies by location. Some offices accept walk-in appointments, while others require you to schedule in advance. During peak times, such as after a new military fiscal year begins or following a deployment, appointment wait times can extend several weeks. You should contact your nearest office as early as possible to understand their scheduling process.
When you call or visit the office to schedule, have your information ready. You will likely need to provide your full name, Social Security number, date of birth, and reason for the appointment (new card, renewal, replacement, or dependent card). Some offices allow online scheduling through military personnel systems, while others still require phone calls or in-person visits to book an appointment.
It is helpful to ask about the typical appointment duration when you schedule. Most CAC appointments take 15 to 30 minutes, but this can vary. Also ask what the current appointment availability is. If your local office has a long wait, you may have options to visit a different location, particularly if you are traveling or relocating.
Practical Takeaway: Use the Department of Defense CAC locator tool to find the nearest issuing office. Contact the office at least two to four weeks before you need your card to understand appointment availability and scheduling procedures. Ask about typical wait times and whether walk-in appointments are accepted.
Reviewing and Updating Your DEERS Information Before Your Appointment
Your DEERS record is the foundation for CAC issuance. Before your appointment, understanding what information is in DEERS and making sure it is accurate can prevent delays or complications. You can review portions of your DEERS information through military online portals if you are an active duty member or retiree. Family members may need to contact their sponsor or the military personnel office to learn what information is on file.

Common issues that affect DEERS records include outdated addresses, misspelled names, incorrect Social Security numbers, and missing or incorrect dependent information. If you have moved recently and have not updated your address with the military, your DEERS record may still show your old address. When the CAC office checks DEERS during your appointment, this discrepancy may need to be resolved. Bringing updated address documentation can help resolve this quickly.
Name changes are another area where DEERS records sometimes contain errors. If you have changed your name due to marriage, divorce, or legal name change, make sure your military record reflects this. You will need to provide documentation of the name change, such as a marriage certificate or court order. The CAC office can help update DEERS during your appointment, but having this documentation ready will speed the process.
Dependent information in DEERS must be accurate for family members to obtain CACs. If you are a spouse or child seeking a CAC, verify that the military sponsor's information in DEERS includes you as a dependent. If there are any questions about your relationship to the sponsor or your dependent status, bring documentation such as a birth certificate or marriage certificate.
You can also prepare for your appointment by reviewing any previous CAC paperwork you have. If you have renewed your CAC before, you may have forms or records showing what information was previously submitted. Comparing this to your current information will help you identify what has changed and needs updating.
Practical Takeaway: Before your appointment, verify that your current name, address, Social Security number, and dependent status are correct in DEERS. If you have changed any of this information, gather documentation of the change and plan to bring it to your appointment.
