Just my take, but when I think tail number I think of military aircraft and I have read that the number represents the year ( not sure if fiscal or calendar) the U.S. government issued or awarded the contract for the building of that particular aircraft ( usually the first two numbers) followed by numbers assigned by the aircraft manufacturer.
Now the term tail number is used by some for identifying civil aircraft and usually is the "N" number assigned to civil aircraft.
