When to report a lost passport
A passport that was still valid when it went missing should be reported once you are satisfied that it is gone. The report cancels the passport electronically, after which it cannot be used for travel or presented as identification by anyone who finds it, including you. Because the cancellation cannot be reversed, search your usual places first: luggage, coat pockets, desk drawers, the glove box, and anywhere the passport was last used. A passport that had already expired when it was lost is not reported, since an expired passport cannot be used for travel in any case; it is simply recorded on the replacement application. A report you have already made is not repeated.
