United States Passport Card

The passport card is a limited travel document, valid only for land and sea travel within North America (Canada, the United States, Mexico, the Caribbean, and Bermuda). It cannot be used for international air travel. The Department of State indicates that this is because ``designing a card format passport for wide use, including by air travelers, would inadvertently undercut the broad based international effort to strengthen civil aviation security and travel document specifications to address the post 9/11 threat environment''.
