Dog Tag

During the American Civil War of 1861-1865, some soldiers pinned paper notes with their name and home address to the backs of their coats. Other soldiers stencilled identification on their knapsacks or scratched it in the soft lead backing of the Army belt buckle.

Manufacturers of identification badges recognised a market and began advertising in periodicals. Their pins were usually shaped to suggest a branch of service and engraved with the soldier's name and unit. Machine-stamped tags were also made of brass or lead with a hole and usually had (on one side) an eagle or shield and such phrases as "War for the Union" or "Liberty, Union, and Equality." The other side had the soldier's name and unit and sometimes a list of battles in which he had participated.

A New Yorker named John Kennedy wrote to the US Army in 1862, offering to furnish discs for all officers and men in the Federal Army, enclosing a design for the disc. The National Archives now has the letter along with the reply, a summary refusal without explanation.

In the Spanish-American War, soldiers purchased crude stamped identification tags.

The US Army first authorized identification tags in War Department General Order No. 204, dated December 20, 1906, which essentially prescribes the Kennedy identification tag:

"An aluminum identification tag, the size of a silver half dollar and of suitable thickness, stamped with the name, rank, company, regiment, or corps of the wearer, will be worn by each officer and enlisted man of the Army whenever the field kit is worn, the tag to be suspended from the neck, underneath the clothing, by a cord or thong passed through a small hole in the tab. It is prescribed as a part of the uniform and when not worn as directed herein will be habitually kept in the possession of the owner. The tag will be issued by the Quartermaster's Department gratuitously to enlisted men and at cost price to officers ..."
