DD214 Separation Codes: Full List and What Each One Means

If you are looking at a short string of letters in Box 26 of your DD Form 214 and wondering what it means, you are in the right place. That string is your separation code. This code explains why you have left active duty. Below you can look up common DD214 separation codes, see what each one means, and learn how the code affects your benefits and job prospects. There is also a section on how to fix a code you believe is wrong.

What is a DD214 Separation Code?

A separation code is a short set of letters on your DD214 that records the reason for your discharge. Each military branch keeps its own list. There are hundreds of codes that exist, and various codes can point to the same reason.

The codes have several names. SPN codes (Separation Program Numbers), SPD codes (Separation Program Designators), and Spin codes, which all refer to the same thing. Employers sometimes read the code to learn how a person left the service, which is one reason it helps to know what yours says.

The Department of Defense no longer releases the official meanings to the public. The lists that are currently circulating online, including the one below, were gathered before the transition. Codes can be added or updated, so treat any meaning as a strong guide rather than a guarantee.

Where to Find the Separation Code on Your DD214 (Box 26)

Military separation codes can be found in Box 26 of the long form DD214. The code works together with three other blocks on the form, and reading them side by side gives you the full picture:

• Box 23, Type of Separation: explains how you left. For example, release, discharge, or retirement.
• Box 24, Character of Service: your discharge characterization. For example, honorable or general discharge.
• Box 26, Separation Code: the SPN or SPD code is covered on this page.
• Box 28, Narrative Reason for Separation: a plain-language version of the same reason.

If Box 26 is blank or you only have the short form, you can request a replacement DD Form 214 to get the full copy. If you are unsure whether you should even have a DD214? Here is who receives one.

DD214 separation codes list

The codes below are the ones veterans run into most often, grouped so similar reasons sit together. A first letter often signals the branch or category, and the letters that follow point to the reason, which is why you will see families like FBK, JBK, KBK, and LBK all tied into completion of service.

This is a working reference, not the full official register. If your exact code is not here, check the branch that issued your form.

Common Separation Codes Worth Knowing

A few codes will come up repetitively. One of them is worth a closer look.

The MBK Code

MBK is one of the most searched codes for a reason. In most cases, the MBK separation code means completion of required active service or expiration of the term of service. This usually appears on Air Force records. In plain terms, it means you finished your commitment and left on schedule. That is a routine, favorable reason for separation, so an MBK code is generally nothing to worry about.

Other Codes You May See

Beyond MBK, common reasons include pregnancy or childbirth (FDF), parenthood (FDG), a physical disability handled through a physical evaluation board (the F-series disability codes), and completion of service (the BK family). Codes tied to misconduct, a failure to meet standards, or an involuntary discharge tend to draw more attention from employers, which is why it helps to know exactly what yours says.

Separation Code vs. Character of Service

People often confuse the separation code in Box 26 with the character of service in Box 24. They are not the same thing.

The character of service is your discharge characterization. There are six types, and most people find them easier to read than the codes:

1. Honorable. The best result. An honorable discharge means you served well and keeps every benefit on the table.
2. General, under honorable conditions. You served acceptably but fell short in some area. A general discharge keeps most benefits, though an employer may look at your separation code to see why.
3. Other than honorable (OTH). The most serious administrative discharge, often tied to security issues, trouble with civilian authorities, or drug use.
4. Bad conduct (BCD). Handed down through a court-martial and sometimes paired with confinement.
5. Dishonorable. The most punitive discharge, reserved for severe offenses like desertion or other crimes under the Uniform Code of Military Justice. You can read more about how a dishonorable discharge shows up on records.
6. Entry level (ELS) or non-characterized. Given to personnel separated in the first 180 days. It is neither positive nor negative, and it also covers some medical discharge cases handled before service is characterized.

Your separation code adds the specific reason behind whichever characterization you received.

How Separation Codes Affect Benefits and Jobs

The reason you left can shape what comes next, so this is the part most veterans care about.

Not every veteran receives the same benefits, even after a full term of active duty. A home loan guaranty, VA health care, education benefits, and severance pay can all hinge on how you separated. An unfavorable code or characterization can limit what you qualify for, and losing health coverage in particular can be costly for a service member and their family.

Some employers, especially in law enforcement and government roles, read the code to decide whether an applicant fits. A code tied to misconduct can raise questions. However, a routine code like MBK does not. If someone was discharged over a failed drug test or a similar issue years ago, the code may not reflect who they are today. This is the importance of the appeal process. Please see more details below regarding this process and why it is beneficial.

How to Fix a Wrong or Unfair Separation Code?

A code can be entered incorrectly, and the reason behind it can be worth challenging. You have two main routes.

Discharge review (DD Form 293). If you want to upgrade your discharge or change the reason and narrative, you can file a discharge review using DD Form 293. You will provide your branch, personal details, and the reason you believe an upgrade is warranted.

Correction of records (DD Form 149). For a clear error, such as a typo in the code, a correction of military records is often the better path.

Something that is important to know is that requests generally should reach the appropriate board within three years of discovering the error. We encourage those to complete this in a more timely manner. It is important to gather supporting documents due to the fact that the board weighs evidence and the process is lengthy. A veterans service organization can help you build the case at no cost. If your goal is to update the form itself after discharge, here is a guide on how to update a DD214.

Conclusion

Considering the massive impact a few letters on your DD Form 214 can have on your future. You should be careful in ensuring that all portions of your file are accurate; this includes your separation code. Given hundreds of separation codes, you may be tempted not to bother understanding this portion in your file. After all, the type of discharge seems enough, right?

However, knowledge is power. Not everything is final once you receive your DD Form 214. There may be a chance for you to have your military file upgraded or changed. Hence, you should maximize your resources and fight for your rights.
