Gemini on Question 17, Sep 29

In the original Ian Fleming novels, James Bond’s actual passport number is never stated.

While Fleming was famous for his meticulous attention to detail (often called the "Fleming effect" or "Fleming sweep"), and provided extensive biographical data for Bond—such as his exact height, weight, scars, eye color, and weapon specifications in the SMERSH dossier in From Russia, with Love, as well as his detailed family history in his You Only Live Twice obituary—he never provided the exact numerical string for Bond's personal British passport.

When traveling, literary Bond either simply "hands over his passport" to immigration officials, or he travels using forged passports provided by the Secret Service under aliases (such as Peter Franks, David Somerset, Sir Hilary Bray, or Mark Hazard).

If you are thinking of a specific passport number, you are likely thinking of the film franchise. In the Daniel Craig films, beginning with Casino Royale (2006), James Bond's official British passport is shown clearly on screen, and his passport number is 07360251.
