United States World War I Service Records

Official Military Personnel Files
The National Personnel Records Center (NPRC) in St. Louis maintains World War I Official Military Personnel Files (OMPFs).

Access to Non-Archival Military Service Records is limited. Non-Archival records are those of service members who separated from the military less than 62 years ago. See Access to Non-Archival Records for more information. Records of individuals who left service more than 62 years ago are considered Archival Records and become records of the National Archives open to the general public.

Records Loss
On July 12, 1973, a fire at the NPRC destroyed approximately 16-18 million Official Military Personnel Files. The affected record collections are described below.

No duplicate copies of the records that were destroyed in the fire were maintained, nor was a microfilm copy ever produced. There were no indexes created prior to the fire. In addition, millions of documents had been lent to the Department of Veterans Affairs before the fire occurred. Therefore, a complete listing of the records that were lost is not available. Nevertheless, NPRC uses many alternate sourcesin its efforts to reconstruct basic service information to respond to requests.

 * Index to Rendezvous Reports, Naval Auxiliary Service, 1917–1918. National Archives Microfilm Publication T1100. (FS Library film ) Lists the name, enlistment date, date of assignment, and place.
