Obtaining Military Records

1. Getting Started

Individuals beginning a search for military records would be well served by first obtaining as much information as possible through family and home sources.  The most important information you need to conduct military research for Naval service during World War II is the following:

  • Full name
  • Date and place of birth
  • Date and place of death
  • Naval Serial Number
  • Enlistment and discharge dates (or years)
  • A unit at some point in time if researching Army or Army Air Force service.
  • A discharge paper is helpful if you can obtain a copy.

Armed with this information, you will be able to retrieve the Official Military Personnel File (OMPF) or Individual Deceased Personnel File (IDPF) for anyone who served in the U.S. Navy.

2. Researching Military Service Part 1

While there are many things to know about military research, we are providing you with the basics to start your research journey.

A.1. What You Need to Know to Begin. Military research, regardless of branch, from World War I through Vietnam, is conducted in two parts. Part 1 is to obtain essential records from the National Personnel Records Center (NPRC) in St. Louis, Missouri. Primarily the OMPF, and if your veteran died while in military service, the IDPF. Additionally, you can search online for more information.

After obtaining records you can create a timeline of service to reconstruct the footsteps of your veteran. Then you can proceed to Part 2 of the research process, which is to learn the context of your veteran’s service. This research journey begins at the National Archives and Records Administration (NARA) in College Park, Maryland.

It is never a good idea to use a final unit or list of units, ships, or stations from a death record or discharge paper as the absolute truth of military service. Most individuals served in multiple units or moved through Replacement Depots. Sometimes the Naval discharge papers can’t accommodate all the ships and stations someone served. For other branches, the final unit listed may be a unit they moved through for discharge. Always do your homework and put a timeline together using the information below. Once you do this, then you will save time and money in Part 2, learning the context of service.

A few things to know. In 1973 there was a fire at the NPRC which destroyed approximately 80% of the Army and Army Air Force/Air Force OMPFs. The Navy, Marine Corps, Coast Guard and Merchant Marine OMPFs were basically unaffected. This means if you submit a request for these branches, you will be able to obtain a copy of your veteran’s OMPF. If you are searching for other family members who were in the Army or Army Air Force, there is a possibility their OMPF did not survive the fire. In that case, you will need the information listed in the getting started section in addition to a unit at some point in time. More on this below.

Using the OMPF and other records you may locate within your family’s archives or online, you should construct a timeline of service to help you reconstruct the footsteps of your veteran. This can be as simple as a three-column table. Column 1 contains the date of the record you are viewing, like a Discharge Paper. Column 2 contains the unit or ship or station in which someone served on that date plus their location. Column 3 contains notes and information from the document.

The timeline of service allows you to see where gaps are in your research, where there are errors, and where you may have new questions to answer. It also allows you to Google Map the footsteps or ports at which your Armed Guard veteran docked.

As an option to help you keep track of where you obtained the information, you can put a footnote in column three and document the source of the information. This can be helpful because military records sometimes contain errors or conflicting information. Knowing where you originally obtained the information can help you quickly compare what you have located. We strongly recommend that you source your entries because should you later decide to write a story or a book, the timeline of service may serve as a basic story or book outline.

Important! The OMPF will provide you with the outline of service to learn the unit/ship/station, where someone may have been, illness, death, Prisoner status, and training. It does not provide the full documentation of your veteran’s service but it is a start point to help you locate more information.

A.2. Federal Government Resources. The National Personnel Records Center (NPRC), Military Personnel Records is the repository for the personnel, health, and medical records of all discharged and deceased veterans (all branches of the armed forces) who served after 1900. NPRC serves as the current home for all IDPFs.

Request the OMPF.

Please note: There is a myth you must be the next-of-kin to retrieve any military records. This is incorrect. If a service member died or was discharged by 62 years ago today, those OMPFs are available to anyone. Unredacted. This is a rolling date.

If your veteran did not die or was not discharged 62 years ago until let’s say, next month, then it’s better to wait until the 62-year deadline has passed before submitting a request. If you choose not to wait, you may get a one-page outline of service or a redacted file.

Veterans and their next-of-kin may now use the online “eVetRecs” service to request records from the Center. Veterans and next-of-kin without Internet access and all others may submit their requests in writing to:

National Personnel Records Center
Military Personnel Records
9700 Page Avenue
St. Louis, MO 63132-5100

If possible, use a Standard Form 180 for the mail-in request. The form may be downloaded, completed and mailed to the NPRC.

If you cannot obtain a Standard Form 180 for this request, you can write a letter. Include in your inquiry the service member’s complete name, Service Number or Serial number, branch of service, and dates of service as well as your return address. Date and place of birth for the veteran would be helpful too, as would be place of discharge, last unit of assignment, and place of entry into service, if known. Include a copy of the discharge paper if you have one. Never send original documents. You must sign and date your request.

More than one request may be submitted per envelope but policy requires that you submit a separate form/letter for each individual whose records are being requested. Please allow several weeks to several months for a reply. If you need assistance, telephone the Center at (314) 801-0800 or contact them via email at stl.archives@nara.gov.

Casualty Information.

Request the IDPF.

Military personnel who died while in military service will have an additional record you can request at the NPRC. The Individual Deceased Personnel File (IDPF). This file was created for anyone who died while in service or anyone who was declared Missing In Action (MIA) and never recovered. MIAs were eventually declared deceased. The IDPF exists for all military branches and also the Merchant Marine, even though they were not an official military branch during World War II.

In the IDPF you will learn details about a service member’s death, burial locations, and basic military service information. It may also contain letters from family members, (rarely) a photograph, Prisoner of War information, maps and brief unit history details concerning individuals who were declared Missing In Action (MIA). These files range from 20 pages to over 350 depending on the circumstances of the death and recovery.

Service members who were considered MIA may have another piece of information in their files. A Finding of Death or FOD. The FOD was issued one year plus one day after someone was declared MIA. This date is the military’s official death date of that service member. It may not be the actual date he was killed or died. The military issued the FODs to allow families to close estates, receive death payments, and begin to move on with life. If you have information that your service member died a certain date but their official death date you discover on Ancestry or Fold3 is a year or more longer, then it’s possible there is a FOD involved.

Finally, if you lost someone in World War I, the NPRC has a file called a World War I Burial File. It is a more basic death file than the World War II/Korea/Vietnam IDPF. Both the World War I Burial File and IDPF can be ordered through the NPRC using Form-180 or by sending in a request.

Additional Places to Locate Casualty Details

Many databases and websites exist to locate casualty and grave information. Some may provide you with the serial or service number you will need to conduct research. These include but are not limited to:

American Battle Monuments Commission (For those interred in an overseas American Military Cemetery or still MIA and listed on a Tablet or Wall of the Missing).

Ancestry Databases

Fields of Honor Database

FindAGrave

Fold3.com

A.3. State Archives. State agencies may be valuable contacts as well. The Military Records and Research Branch of the Kentucky Department of Military Affairs, for example, contains more than 300,000 discharge documents for Kentucky veterans beginning with individuals who served in World War I through modern day.

State Archives may also hold Veterans Compensation Files, also known as Bonus Applications. Not every state participated in this compensation plan, but it is worth checking the state in which your veteran lived after the war to see if this exists.

After World War I and World War II (and in some states more recent wars), veterans were allowed to apply for a bonus payment in the state in which they lived after discharge. Each veteran, or if the veteran died in service, their beneficiary, was allowed to apply. These applications contain basic biographical information, work and education details, and basic service details (service or serial number, enlistment and discharge dates). Often you will find information on family members, a discharge paper and other materials.

Ancestry.com has available two sets of Veterans Compensation Applications. One for Iowa veterans (application only). Pennsylvania is also available in what appears to be a full application file (application and corresponding records). Even if you are able to obtain the application online, it’s a good idea to contact the State Archives and request a copy of the full application packet with discharge paper.

A.4. County Records. Although the federal government is the primary source for military records, other sources may be close at hand. Local governments, for example, merit a researcher’s attention. After all wars, veterans were encouraged to file a copy of their discharge papers (later DD-214) with the County in which they lived. Most often you will find these held by the County Recorder or County Clerk. Every county and state has different access rules so be sure to inquire.

A.5. Military Records are Everywhere. While we begin our research at the NPRC and NARA, it’s important to note that military records can be found all across the country. A few places you might search include: Presidential Libraries, university libraries and archives, local libraries, genealogy and historical societies, ethnic libraries and museums, branch-specific museums, the National WWII Museum, even those tiny libraries, archives, and museums that barely have a website may hold information helpful to your research. Additionally, you may find records, photographs, maps, and diaries at archives in Europe, Australia, the Pacific Islands on which we fought, and many other locations around the world.

3. Researching Military Service Part 2

Once you know the ships/stations or units in which your veteran served and have created the timeline of service, it’s time to locate records to help you understand their experience. These records may come in the form of unit histories, After Action or Mission Reports, Armed Guard Report, maps, photographs, unit journals, and many other possibilities. These records will provide you with sometimes graphic details about a battle, daily events, or individual deaths.

While there was a standard by which every military record was to be completed, you will discover, regardless of military branch, that some report writers documented the bare minimum while others wrote extensively detailed reports.

You will want to begin your search at the National Archives and Records Administration (NARA) at College Park, Maryland. This is where unit records are held for all the military branches. For Naval Records, it is a good idea to also check the Naval History and Heritage Command as well. Please see below for more information on Merchant Marine records.

4. Merchant Marine Records

This information is current as of May 2025.

Locating information on a Merchant Mariner is not as difficult as it was prior to 2020 when records were scattered across many different archives and repositories. First, all the Merchant Marine OMPFs and IDPFs are located at the NPRC. Those files can be requested using the information above.

Second, NARA at College Park, Maryland has many of the vessel histories and other documents concerning the ships on which the Naval Armed Guard served. In some cases, you will also need to check the Regional NARA facilities closest to where the vessel usually docked, to see if vessel histories, Armed Guard reports or other documents exist.

Since Merchant Marine histories and reports have been moved from Regional Archive Branches to National Archive Branches and back a lot the last 15 years, you will require patience, money, and time if you plan to physically go to these archives and research. What you think is at one archive may actually be at another.

If you are unfamiliar with the records, don’t have time or patience to figure out where they are if you have a short trip planned, you might hire a professional researcher to help you. Professional researchers know their way around the archives, have connections, and can obtain records much faster. Details on suggested researchers can be found below.

Seeking Veteran Status for Merchant Mariners

World War II Merchant Marine veterans seeking official veteran status and to qualify for certain limited veteran benefits should likewise contact the Coast Guard’s National Maritime Center. Before World War II Merchant Mariners can receive veterans benefits, it is necessary first to submit a DD Form 2168. Full details can be found at the National Maritime Center website linked above.

5. Ship Records

  1. Records of U.S. Navy and Merchant Ships and Naval Units From the Modern Era; National Archives and Records Administration

The National Archives at College Park, Maryland has custody of a wide range of records relating to warships, merchant ships on which Armed Guard units served, and other Navy units for the period from World War II through Vietnam, with a heavy concentration in World War II records. Available records include, but are not limited to:

To learn more about the scope of these materials and to request records or media for a given ship, you can email NARA to submit a request at inquire@nara.gov.

If you are unable to visit NARA to conduct research, you can order records or media by sending a letter to:

NARA

8601 Adelphi Road

College Park, MD  20740

In your email request or letter, include the ship/unit’s name, the date/time period of interest; your full name, address, email, telephone number; and as much other detail as possible about the information you would like to obtain. Due to the volume of requests received and the time needed to identify all appropriate records, Archives staff requests that you limit your request to five items per letter. Allow several weeks from the initial inquiry to receipt of the records.

A charge will be imposed for reproduction/mailing of the records, however, do not send any cash/check/charge card information with your initial inquiry. The archives staff will review your request and email you an estimate of the cost and payment information. Follow the directions contained in that letter or email to order the desired records.

6. Additional Information for Other Military Branches

Are you researching other military service beyond the Navy or Merchant Marines? If so, we have some tips for you. In general, the most important records you need to learn the basics of your veteran’s service are broken down below by branch.

Navy, Marine Corps, Coast Guard, and Merchant Marines

From the NPRC: OMPF, VA Index, and if needed, the IDPF.

From NARA College Park (as a start point for research): Unit level records, photographs, maps. Then start checking branch-specific museums and archives for more records.

Army and Army Air Force / Air Force

From the NPRC: OMPF, VA Index, and if needed, the IDPF.

Due to the destruction of so many OMPFs in the 1973 Fire, you will learn more about your veteran’s service if you have a unit in which they served at some point in time. This may be found on a discharge paper, death record, VA Index Card obtainable only through the NPRC, a letter or V-Mail, newspaper article, or other genealogical sources. Once you have a unit you can then, whether or not the OMPF burned, have Payroll records, Rosters, and Morning Reports searched.

The archivists at NPRC will not do deep research for you. You will need to go there or hire a researcher to obtain the Payroll, Rosters, and Morning Reports which will help you reconstruct military service. The Morning Reports are indexed by Company but if you know what infantry regiment or tank battalion, etc., then it is possible to have a researcher search to locate your veteran. Saying your veteran was in the 101st Airborne is too high a level to search unless you have unlimited funds to pay a researcher for the time to search.

NARA has been digitizing the Army and Army Air Force Morning Reports and placing them on the NARA Catalog (see section on this). However, not all the reports are there and due to the quality of some of the records, you will not easily be able to trace your veteran right now until more work is done to index the reports. It is a good idea to search by name or service number because you may find information in a Special Order which can help build the timeline. Those Special Orders can also be given to a professional researcher to dig further where a Morning Report doesn’t list transfers to different units.

From NARA College Park (as a start point for research): Unit level records, photographs, maps. Then start checking branch-specific museums and archives for more records.

7. Do It Yourself or Hire a Researcher

No matter how you do it, military research is not completely free of expense. If you choose to go it alone and travel to archives to conduct research yourself, you will end up paying for travel, hotel, meals, and possibly records. Those unfamiliar with the records and archive may also lose time to learning how to maneuver through it all. Plus, you must schedule a trip and possibly wait weeks or months to make the trip. If you hire a researcher, you will end up paying as well but receive the records much faster and not have to leave your desk!

With basic knowledge of important records to obtain and a general idea of where to find those records, anyone can conduct military research. However, sometimes it is valuable to hire a professional who knows their way around the archives, specific record sets, websites, and can more quickly pull the records for you. And, in some cases, provide an explanation of what the records contain or write a book for you. Researchers vary in services offered so it’s best to determine your needs before hiring someone.

8. Online Resources

Each day numerous military records are added to websites and databases and it would be impossible to list every possibility here. Instead, we offer you the most commonly used websites and databases for Armed Guard and Merchant Marine research.

  1. Ancestry.com

The website Ancestry.com, which is more commonly used for genealogical research purposes, provides access to a database of passengers arrivals in the Port of New York from 1820 to 1957. Included in this database are the names of Armed Guard and Merchant Marine crew members whose ships arrived in New York during World War II.

U.S., Applications for Seaman’s Protection Certificates, 1916-1940

U.S., Departing Passenger and Crew Lists (1914-1966)

U.S., Merchant Marine Applications for License of Officers, 1914-1949

US, Navy Muster Rolls, 1949-1971

U.S. Navy Support Books, 1901-2010

US, World War II War Diaries, 1941-1945

9. Searching the NARA Catalog

The NARA Catalog has tremendous resources available to researchers and more digitized record sets are being added daily. While this resource is incredible, it can be frustrating to search and find what you seek, especially when you know it exists online.

What’s the issue with NARA’s Catalog? First, you must understand that the microfilm reels are digitized backward which can be confusing for some. Second, rather than take you directly to a record with the possible name or serial number you searched, it takes you to a group of records. That group may contain 100s or thousands of pages of results which you will have to navigate through to find what you seek.

To add to this group result issue, sometimes when you click the results, it will provide you with a dropdown of record/page numbers you can click to find the information for which you searched. However, the catalog is finicky and doesn’t always provide this dropdown which means you could be stuck navigating through thousands of pages within a specific search result.

TIP! When you encounter a set of records in the catalog, be sure to check FamilySearch, Fold3, or Ancestry to see if that same record set can be found. If it exists, those sites will make it easier for you to search and find results. For example, the Naval Muster Rolls are digitized and available on NARA’s Catalog, but they are much easier to use on Fold3.

Searching for Army and Army Air Force Morning Reports. The website, A Week in Genealogy, has a great breakdown in a blog post on how to search for these vital records if you are searching Morning Reports on NARA’s Catalog. Please use her search suggestions to find your information.
