Have you always had an interest in planes? If so, you probably know a thing or two about different types of aircraft. Maybe you can tell a plane’s make and model, just by looking at it. Perhaps you can even tell what year an aircraft was built with just a few clues. Those details tell a story about an airplane and what it is used for, and so too does an N-number. Also commonly called a “tail number”, this string of alphanumeric digits serves to identify an aircraft and is issued by the Federal Aviation Administration (FAA). Tail numbers have a long history, dating all the way back to the International Air Navigation Convention of 1919. At that conference, different countries were assigned different letters to denote aircraft call signs. The United States was given the letter “N”, and it is still used to this day.
