American WW2 Dog Tags

.

American soldiers who served during World War Two were issued with the M1940 Identification (ID) tags stock No. 74-T-60. These tags featured the distinctive notch cut out and were issued to personnel until 1964.

The information on the WW2 American Dog tags was stamped into the tags by a special machine, modern tags are embossed so they look different when printed. Modern ones look neater as they use machines similar to the way credit cards are embossed. We stamp our WW2 tags on an original US machine so you can have the correct look.

Creating a US WW2 Army Serial Number

.

The Army Serial Number (ASN) was not a totally random assigned number, you can tell quite a bit of information from a soldiers serial number:

  • From the first digits you can tell if they are enlisted, Warrant Officer, Commissioned Officer or a Flight officer,
  • If they volunteered (Regular Army) or where in the National Guard or where a Draftee into the Army.
  • Where they lived or joined up.
  • Some Branch of Service also had there own specific layout like Nurses, Medical staff and the WAC'S.

.

How to read or make an Army Serial Number.

The Army Service Number is a unique number and is used on all paperwork including military ID cards, Dog tags, Driving licences etc.

From the list below scroll down until you find the appropriate rank or branch of service and learn how to create your Army Serial Number.

 .

Regular Army.

All Volunteers who joined before the war or during the war were called Regular Army. The serial number for Regular Army was made up of 8 digits. The first digit was always 1, the next digits denoted the geographical area in which the soldier enlisted. For administrative purposes the American military split the country up into 9 Corps Areas and 4 Army Areas so if you joined up in an area covered by a Corps area you would have one digit, 1 to 9 and if you joined up in an area covered by one of the Army areas you would have two digits, 01, 02, 03 or 04 after the first digit. The remaining series of 6 digits for the Corps and 5 digits for an Army area enlisted soldier were then assigned giving a total of 8 digits. These last digits can be made up by yourself within the ranges based on command area shown in the table below.

National Guard.

Anyone who joined the National Guard before joining the Army had the first two digits of 20 at the start of their Army Serial Number. The next digits denoted the geographical area in which the soldier enlisted. For administrative purposes the American military split the country up into 9 Corps Areas and 4 Army Areas so if you joined up in an area covered by a Corps area you would have one digit, 1 to 9 and if you joined up in an area covered by one of the Army areas you would have two digits, 01, 02, 03 or 04 after the first digit. The remaining series of 5 digits for the Corps and 4 digits for an Army area enlisted soldier were then assigned giving a total of 8 digits. These last digits can be made up by yourself within the ranges based on command area shown in the table below.

Army Service Number

.

The US Army service number was an eight digit number which gave an idea of where the GI was from, the service number was prefixed by one or two letters which meant the following.

       RA       Regular Army, volunteer enlisted.
       US     
  Enlisted Draftee.
       NG     
  National Guard.
       ER     
  Enlisted Reserve.
        O

4 Southwest America.
5 Midwest America.
6 California, Pacific coast, Hawaii or Alaska.
0 Indicated outside America like Puerto Rico, Virgin Islands or America Samoa.

 .

USMC Service Number

.

During the early part of the Second World War, the Marine Corps extended their enlisted service numbers to the number 1,000,000 with numbers broken down into sub-sections reserved for particular groups enlisting during World War Two. The first group, ranging numbers 350,000 to 670,899, were standard Marine Corps enlistees joining for wartime service. Numbers 670,900 to 699,999 were never issued and 700,000 to 799,999 were reserved for female enlisted personnel. The female enlisted service numbers were also the only numbers assigned a prefix code, as the letter 'W' was used to denote female Marine Corps enlisted.

Until the middle of World War Twp, the remaining service number range of 800,000 to 999,999 was used by regular Marine enlistees. In 1943, the Marine Corps extended enlisted service numbers to 1,699,999 even though the original one million service number cap had not yet been reached.

Service numbers 1,700,000 to 1,799,999 were set aside for female enlisted personnel of the 1960s and 1970s while 1,800,000 to 2,000,000 was used by male enlistees. In 1965, with male service numbers running out due to a rise of enlistments during the Vietnam War, the Marine Corps extended enlisted service numbers a final time to 2,800,000. In 1972 the Social Security numbers was used as the primary identification means for service members.

USN Service Number

.

Officer.

An officer's service number ranged from 0 - 999,999 and was issued based on date of commission. This ran from the 1920's until 1972 when the Navy moved to use social security numbers.

.

Enlisted.

Navy Enlisted service numbers ran from 1,000,000 - 9,999,999 and until the 1930's the 1st digit was issued based on enrollment decade. example from the 1920's: 212 34 56.

It was realised that that if large numbers were to enlist the numbers would run out so before the outbreak of WW2 it was changed so that the 1st digit was based on an enrollment district then a 6 digit personal identifier.  Example: 312 34 56.

From 1965 to 1971 soldier's were issued with a 'B' series service number. The number began with the letter B and 6 digits as a personal identifier. in 1969 a 'D' series was also added. In 1972 the Navy had moved to using social security numbers. Example B12 34 56.

.

Women.

The Navy used the suffix W which was issued from 1948 until the late 1960s to female enlisted personnel. The "W" suffix was written behind the service number of any officer or enlisted Navy member who was a woman. This practice was discontinued in early 1970, shortly before the discontinuance of service numbers as a whole.
