If your passport is lost or stolen you must report it to the State Department right away. How you replace it depends on if you are inside or outside the U.S.
Once you have reported your passport lost or stolen, the State Department invalidates it. You cannot use it if you find it.
If you are in the U.S. and your passport is lost or stolen, you must use Form DS-11 to apply for a new passport in person. Follow the guidance from the State Department, which is based on how quickly you need your new passport. Check current processing times to find out how long it will take.
If you are outside the U.S., contact your nearest U.S. embassy or consulate to replace your lost or stolen passport and find out how long the process will take. In some cases, you may be able to get a limited-validity passport if there is not enough time to get a regular passport. Learn more about passports lost or stolen abroad.
