What Does "P" Mean on Dog Tags?

If you’ve ever seen a military dog tag and wondered what the letters mean, you’re not alone. One of the most common questions is: What does "P" stand for? The answer is simpler than you might think—Protestant.

Dog tags have long served as a soldier’s essential identification, carrying critical details like name, service number, blood type, and religious affiliation. The inclusion of religion dates back to World War II, when the military needed a quick way to ensure proper burial rites in case of death. At the time, only three religious categories were officially recognized on dog tags: P for Protestant, C for Catholic, and H for Hebrew (Jewish).

This system reflected the dominant religious groups within the U.S. armed forces at the time. While more diverse religious designations are used today, the tradition of marking faith on dog tags continues. The “P” may seem like a small detail, but it carried significant meaning—ensuring that a fallen soldier would be honored according to their beliefs.

Over the decades, dog tags have evolved, but the core purpose remains: to identify and protect the identity of service members, even in the most difficult circumstances. So the next time you see that little “P,” remember—it’s more than just a letter. It’s a quiet mark of identity, history, and respect.
