Dear Mr. Shaw,
Thank you for posting your request on History Hub!
Military separation and re-entry codes are used to categorize how and why a service member separated from the service branch and the circumstances. The two main codes, Separation and Re-entry are found in Box 26 and 27 on the undeleted DD Form 214. The Department of Defense issues a variety of codes to describe the nature of the service member’s discharge or release and some are publicly available. Until recently, these codes were issued alphabetically, but are now issued numerically. An incomplete list of separation codes can be found here: Military Separation Codes. You may also wish to contact your local VA office in order to obtain more information about the significance of the separation code on your DD Form 214.
If you would like to request a copy of your undeleted DD Form 214, they may be requested from the National Personnel Records Center (NPRC) via fax, mail or online using eVetRecs. Please see the NPRC web page Request Military Service Records for details and Emergency Requests and Deadlines for the procedures to use for time sensitive requests.
