With colorful festivals, lively cities, some of the world’s greatest archaeological monuments, and roughly 7,000 miles of coastline prime for sunning and snorkeling, Mexico is a popular destination for U.S. travelers. Like all countries, Mexico requires travelers to bring their passports, but you might be surprised that there are some exceptions to this rule. These are the travel requirements when heading from the United States to Mexico by land, air, or sea.
Do you need a passport to enter Mexico?
Yes, Americans need a passport book to go to Mexico—by air.
This has been the case since 2009 when the U.S. Department of State implemented the Western Hemisphere Travel Initiative (WHTI), which requires all U.S. citizens and legal residents to present a valid passport when entering or re-entering the United States from Mexico. The initiative made passports the standard document for travel between the United States, Canada, Mexico, the Caribbean, and Bermuda. Before that, U.S. citizens could travel to Mexico by land and sea with only a valid driver’s license and birth certificate.
What other documents can be used to travel between the USA and Mexico?
If you’re a U.S. citizen without a passport book and are traveling to Mexico by land or sea, you can use a few other documents.
Passport card
The U.S. passport card is a convenient and cheaper alternative to the traditional passport book; it’s good for land and sea travel to Mexico, Canada, and some Caribbean countries. The passport card is wallet-size (much like a driver’s license) and includes information about its owner, including full name, nationality, place of birth, gender, dates of issue and expiration, a unique ID number, and photo.
Note that passport cards are accepted only for land and sea travel between the USA and Mexico. Air travel to Mexico still requires a passport book.
SENTRI pass
There’s also the SENTRI (Secure Electronic Network for Travelers Rapid Inspection) pass, a trusted traveler program similar to Global Entry or TSA PreCheck.
The program requires prescreening and provides participants with a special card that can be used in place of a passport for land border crossings (by car or foot) only. While primarily aimed at frequent cross-border travelers, these programs offer a convenient option for those looking for efficient travel between the two countries.
Enhanced Drivers Licenses
A handful of U.S. states offer Enhanced Drivers Licenses, which contain additional security features that allow them to be used in lieu of a passport for travel to Mexico by car. Enhanced Drivers Licenses are available in Michigan, Minnesota, New York, Vermont, and Washington.
Do you need a passport on a cruise that stops in Mexico?
U.S. citizens can also travel to Mexico (and certain Caribbean islands) without a passport if they’re on a “closed-loop” cruise.
A closed-loop cruise leaves from and returns to the same U.S. port. The rules for sea travel were established under the Western Hemisphere Travel Initiative and allow people from the United States to travel to Bermuda, the Bahamas, and Mexico without a passport on closed-loop cruises only. However, some cruise companies require (or at least recommend) that you have a passport in case of an emergency, such as a medical issue that causes you to fly home early.
So, where can U.S. citizens travel without a passport?
Closed-loop cruises aside, not having a passport doesn’t have to stop you from taking a beach vacation outside the 50 states. There are five U.S. tropical territories/commonwealths you can visit without a passport, as close as Puerto Rico and as far-flung as the South Pacific paradise of American Samoa.
