What is a Dog Tag? From Military Identification Tag to Trendy Piece of Jewelry
What is a dog tag?
A dog tag is a flat, rectangular piece of metal with rounded corners worn on a chain. Originally, it served as military identification, containing personal data such as name, blood type, and religion. Today, dog tags are popular fashion accessories for both men and women — they can be personalized with names, dates, symbols, or gemstones.

History of the dog tag
The dog tag originated during the American Civil War (1861–1865), when soldiers made their own cardboard or wooden tags to enable identification on the battlefield. During World War I, metal identification tags were standardized in many armies. The nickname "dog tag" came about because the tags resembled dog identification tags. In World War II, dog tags were worn in pairs — one remained with the body, one was taken for registration. From the 1990s onwards, dog tags became popular as a fashion accessory in streetwear and military style.
Materials and design
Stainless steel — the most popular choice: durable, colorfast, and affordable. Silver-colored stainless steel — classic and timeless. Gold-colored stainless steel — warmer and more luxurious in appearance. 925 silver — premium choice, nickel-free. Titanium — lightweight and 100% nickel-free, ideal for sensitive skin. Information is engraved or stamped on the surface. Dog tags are worn on a ball chain or a finer link chain. Combine with matching gold-colored necklaces for a complete look.
Personalization of a dog tag
A dog tag can be personalized with a name, date, initials, personal message, or symbol. Engravings are applied via laser engraving or mechanical engraving. Some dog tags are adorned with gemstones or enamel for an extra personal touch. A personalized dog tag is also a popular gift for birthdays, anniversaries, or as a keepsake.
