Dear Melissa Burke,
Thank you for using the History Hub.
The National Personnel Records Center in St. Louis would be your first point of contact: The National Personnel Records Center (NPRC. You can begin the process of requesting your DD-214 by visiting the link provided here: https://www.archives.gov/veterans/military-service-records/. You can submit a request online as well using the eVetRecs portal as well here; https://www.archives.gov/veterans/military-service-records/evetrecs-help.html.
You may want to request a copy of his Official Military Personnel File (OMPF). OMPFs and individual medical reports for enlisted men of the U.S. Army who were separated from the service after October 1912 and before 1959 are in the custody of NARA's National Personnel Records Center (NPRC) in St. Louis. In many cases where personnel records were destroyed in the 1973 fire, proof of service can be provided from other records such as morning reports, payrolls, and military orders, and a certificate of military service will be issued. Please complete a GSA Standard Form 180 and mail it to NARA's National Personnel Records Center, (Military Personnel Records), 1 Archives Drive, St. Louis, MO 63138-1002. For more information see Official Military Personnel Files (OMPF), Archival Records Requests.
Additionally, here is a blog post describing WWII Military Unit Records at the National Archives: https://historyhub.history.gov/community/military-records/army-and-air-force-records/blog/2017/08/25/wwii-military-unit-records-at-the-national-archives
This may be some duplication of the above links, but here is a page on Requesting Veterans’ Service Records from the National Archives:
If you have additional information including your service branch and date of separation, that will assist the NPRC in locating your DD-214.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RRPO (The National Archives at St. Louis). Also, NPRC will continue servicing requests ONLY associated with medical treatments, burials, and homeless veterans seeking admittance to a homeless shelter. If your request is urgent, please see Emergency Requests and Deadlines. Please refrain from submitting non-emergency requests such as replacement medals, administrative corrections, or records research until NPRC returns to pre-COVID staffing levels. Please check archives.gov/veterans for updates to the NPRC operating hours and status. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck in your research.
