The term "007" is a code number and designation given to James Bond, the fictional British Secret Service agent created by author Ian Fleming.

James Bond is the central character in a series of spy novels written by Ian Fleming, starting with the novel "Casino Royale" in 1953.

In Fleming's novels, James Bond is assigned the code number "007" by the Secret Intelligence Service (MI6), which signifies his status as a licensed-to-kill agent with a "00" designation. The "00" prefix indicates that Bond has a license to kill in the course of his duties as a spy.

Ian Fleming reportedly chose the code number "007" because it sounded simple and was easy to remember. The "00" prefix, meaning licensed to kill, was inspired by Fleming's knowledge of British espionage practices and terminology.
