Here you go:
Agent 001 Unknown Referenced in the Raymond Benson novel, Doubleshot.
Agent 002 Bill Fairbanks Assassinated by Francisco Scaramanga, a.k.a. The Man with the Golden Gun, in Beirut, Lebanon, in 1969 (film version: The Man with the Golden Gun). In The Living Daylights (film version), another 002 was in the training exercise at Gibraltar, with 004 and 007.
Agent 003 Unknown Found dead, in Siberia, in A View to a Kill film. Another (presumably unrelated) MI6 agent is Jack Mason, 003 who killed by Nikolai Diavolo, the villain, in the Everything or Nothing video game (2004).
Agent 004 Frederick Warder Accompanied 002 and 007 to Gibraltar in The Living Daylights film; murdered by an individual pretending to be a KGB agent who left a tag on the body that read "Death to Spies" in Russian. Another 004 appears in the Benson novel The Facts of Death. In the GoldenEye video game on the Silo mission briefing, Q mentions to 007 to "remember to treat the timed explosives with respect - you remember what happened to 004 in Beirut" - whether this is another agent or the same one as above is unknown.
Agent 005 Stuart Thomas Was 005 until an eye defect had begun to impair his ability to use a firearm. Was transferred and is the head of Station G (Greece) in Colonel Sun.
Agent 006 Alec Trevelyan Major character in GoldenEye. One of Bond's best friends, he betrayed MI6 and Her Majesty's Government by faking his death and then, years later, in aiding the theft of the secret Soviet satellite, GoldenEye. His motive was avenging his parents, Lienz Cossacks, betrayed to the Communists by the British government after World War II. He also begrudged Bond's not allowing him time to escape unscathed from the Soviet chemical weapons factory they were to destroy in the mission shown in the teaser of GoldenEye. Portrayed by Sean Bean. Another apparent 006, a former Royal Marine commando, is mentioned in the Fleming novel On Her Majesty's Secret Service; this agent is never referenced by name so it is not known if this is also Alec Trevelyan.
Agent 007 James Bond To date, James Bond is the only agent known to have had the code number 007. During the timeframe of the You Only Live Twice novel, Bond was transferred into another branch and given the number 7777, suggesting there was no active 007 during that time frame (Bond was subsequently reinstated as 007 in the following book, The Man with the Golden Gun. In the John Gardner novels, 007 is the last remaining active 00-agent, the section itself having been dissolved by the 1980s; Raymond Benson later contradicted this in his novels.
Agent 008 Unknown In the films, agent 008 is mentioned briefly when M threatens to replace Bond on an assignment, e.g. Goldfinger and The Living Daylights. The James Bond 007 role playing game released in the 1980s suggests 008 is a woman. In the novel Moonraker 008 (called "Bill" by Bond) is mentioned as being on vacation. In the video game James Bond 007, 008 (male) gives Bond an exploding pen before dying in Kurdistan.
Agent 009 Unknown Assassinated by Mischka and Grischka in the film version of Octopussy. M sent another 009, in the movie The World Is Not Enough, to assassinate Renard; despite 009's shooting him in the head, Renard lived. Another 009 dies in the graphic novel Deadly Double, while yet another unlucky holder of the rank is killed in Peru in the graphic novel Serpent's Tooth.
Agent 0010 Unknown Referenced in the Benson novel The Man with the Red Tattoo.
Agent 0011 Unknown Mentioned briefly in the novel Moonraker as vanishing while on assignment in Singapore.
Agent 0012 Unknown Although unmentioned on screen, the novelization of The World Is Not Enough indicates that Bond is investigating 0012's death at the film's start. Nothing is known of 0012 except that a photograph of the agent shows the late 0012 to be a male with dark hair.
Agent 0013 Briony Thorne A female 00-agent who appears in the comic strip Fear Face (published January 18, 1971 to April 20, 1971 in the The Daily Express). Thorne is revealed to be a double agent for China.
Unknown "GoldenEye" A former 00-agent featured in GoldenEye: Rogue Agent. He was shot in the right eye, and was dismissed by MI6 for "reckless brutality". He joined up with Auric Goldfinger against the shooter, Dr. Julius No, and eventually received a gold-hued, synthetic orb as a replacement for his right eye. After killing Goldfinger and Dr. No, he becomes Ernst Stavro Blofeld's bodyguard. Unlike other 00 agents listed here, it is difficult if not impossible to reconcile GoldenEye with the continuity of the films, comic strips, or novels.
Unknown Agent York Killed in the comic strip River of Death (published June 24, 1969 to November 29, 1969 in The Daily Express). Agent York is a 00 agent but his number isn't revealed.
Unknown Suzi Kew A recurring character in the Daily Express comic strip series of the 1960s and 1970s, Suzi Kew is a 00 agent but her number is not revealed.
