Military Records Search: Discover an Ancestor’s Service

Military records can add far more than a rank and unit to a family tree. A draft card may give a precise birth date and physical description. A pension file may contain a marriage record, affidavits from neighbors and the names of dependent children. A service file can establish assignments, promotions and discharge information.

Access depends on the country, branch, conflict and age of the file. Recent personnel and medical records are protected, while older archival records may be open for research. Some U.S. Army and Air Force personnel files were destroyed in the 1973 fire at the National Personnel Records Center, making alternate sources especially important.

Begin With the Veteran You Know

Before requesting a file, gather:

• Full name used during service
• Birth date and birthplace
• Branch of service
• Approximate service dates
• Service number, if known
• Rank
• Unit, ship or station
• Place of enlistment
• Residence before service
• Conflict or campaign
• Date and place of separation
• Names of next of kin

A common name without branch or date may be impossible to distinguish. Family photographs, discharge papers, medals, letters, uniforms and obituaries can supply missing clues.

Types of Military Records

Official personnel files

An Official Military Personnel File may document enlistment, assignments, training, promotions, evaluations, awards, medical information and separation. Contents vary considerably.

Compiled military service records

For earlier conflicts, archives may compile information from muster rolls, returns, pay records and other papers into an individual jacket.

Draft registration cards

Registration does not prove that a person served. Cards can still provide name, birth date, residence, occupation, contact person and physical description.

Pension and bounty-land files

Veterans, widows and dependents submitted evidence to prove service and relationships. Files may contain testimony, marriage proof, children’s birth information and migration details.

Muster rolls and unit records

These show a service member’s presence, status or unit activity. Unit histories explain context but may not name every person.

Casualty and burial records

Casualty lists, battlefield burial files, grave-registration records and memorial databases can document death or missing status.

Discharge papers

Families may possess a DD Form 214 or an earlier discharge document. Protect modern documents because they contain identifying information.

Where U.S. Military Records Are Held

The National Archives states that federal military service records from the Revolutionary War through 1912 are generally held at the National Archives Building in Washington, D.C. Records from World War I to the present are generally associated with the National Military Personnel Records Center in St. Louis, although record groups and unit files may be held elsewhere.

Do not assume the entire file is online. Many individual military records require a formal request or onsite research.

Use the official National Archives veterans’ service records page to identify the current request route.

Archival and Non-Archival Personnel Files

U.S. Official Military Personnel Files generally become archival and open to the public 62 years after the service member’s separation from service. This is a rolling date, not a fixed war-based rule.

Files for people separated less than 62 years ago are non-archival and subject to privacy restrictions. The veteran, next of kin or authorized person may have broader access than the general public.

Fees and required forms differ. Check the current NARA guidance before ordering rather than relying on an old blog post.

How to Request a Military Service File

Depending on eligibility and record type, requests may be made through an official online system or with Standard Form 180.

Provide as much identifying information as possible:

• Complete name used in service
• Service number
• Social Security number when appropriate and lawfully supplied
• Branch
• Dates of service
• Date and place of birth
• Place of entry and separation
• Last unit

State what you need and why. A complete archival file may carry a copying fee, while veterans and next of kin may be eligible for certain records without charge.

Do not send sensitive identifiers to unofficial websites or include them in public family trees.

The 1973 NPRC Fire

On July 12, 1973, a major fire at the National Personnel Records Center destroyed an estimated 16–18 million Official Military Personnel Files. NARA reports major losses affecting many Army personnel discharged between November 1, 1912, and January 1, 1960, and many Air Force personnel discharged between September 25, 1947, and January 1, 1964, particularly names alphabetically after James E. Hubbard.

There was no duplicate collection of every destroyed file. However, NARA may reconstruct parts of service using alternate records.

Possible substitutes include:

• Final pay vouchers
• Morning reports
• Unit rosters
• Hospital admission cards
• Veterans Administration claim files
• Draft registrations
• State bonus applications
• County discharge recordings
• Newspaper reports
• Pension or benefit records
• Family-held discharge papers

Tell NARA if you believe the file was fire-affected and supply detailed unit and service information.

Separate Registration From Service

A draft card proves that the person registered, not that the person entered military service. Likewise, a newspaper list may report selection without showing final induction.

Confirm actual service through:

• Personnel or compiled service file
• Muster roll
• Discharge document
• Pension or benefit application
• Unit roster
• Official casualty record
• Grave marker with corroborating evidence

Avoid adding a branch or rank to a tree based only on a same-name draft registration.

Identify a Soldier With a Common Name

Compare:

• Service number
• Birth date and place
• Residence at enlistment
• Next of kin
• Branch and unit
• Occupation
• Physical description
• Discharge location

Create separate profiles for candidates until the evidence supports a merge. Military indexes sometimes omit middle names or use initials.

Research the Unit After Identifying the Person

Once individual service is confirmed, unit records provide context. They may explain where the unit trained, traveled and fought.

Search for:

• Regimental or unit histories
• War diaries and after-action reports
• Deck logs
• Morning reports
• Maps
• Photographs
• Award citations
• Official histories

Do not assume that a unit-level event happened personally to every member. Write carefully: “His regiment participated in…” is different from “He personally fought at…” unless individual evidence supports it.

Military Pensions as Family Records

Pension applicants had to prove eligibility. A widow might provide a marriage certificate and children’s birth information. Comrades could describe service and later residence. Medical examinations might track long-term disability.

Read the entire file. Contradictions are common because money and eligibility were involved, but sworn testimony can preserve unique family details.

Respect Privacy and Sensitive History

Military files may contain medical conditions, discipline, trauma, disability and family hardship. Apply context and restraint.

• Do not publish modern service numbers or Social Security numbers
• Protect recent medical information
• Distinguish allegations from findings
• Avoid glamorizing trauma
• Explain historical terminology
• Ask living veterans before sharing personal materials

Access to a record does not remove the need for ethical judgment.

Cite Military Records

Include:

• Service member’s name
• Branch and unit
• Record type
• Service number when appropriate in private notes
• File or pension number
• Record group and series
• Repository
• Image or database details
• Access date

For family-facing publications, redact sensitive identifiers.

Common Military Research Mistakes

• Assuming draft registration equals service
• Selecting a same-name veteran without matching identifiers
• Believing every file is online
• Ignoring the 62-year access rule
• Giving personal identifiers to unofficial services
• Treating unit history as individual proof
• Abandoning research after learning a file was lost in the 1973 fire
• Failing to search pension, state and county sources
• Publishing recent medical or disciplinary information carelessly
