What Are U.S. Passport Requirements for Mexico?

The U.S. passport requirements for Mexico have undergone a significant amount of change, partially due to tightened security measures regarding border crossings. The various documentation people require is determined largely by their current status (adult versus minor) as well as their mode of transportation.
Air Travel Guidelines

For United States citizens traveling to Mexico via airplane, the current regulation stipulates that all travelers must have a current U.S. passport book or card in order to cross the border back to the United States.

Sea Travel Guidelines

cruises and ferries traveling between the United States and Mexico have special guidelines regarding paperwork. In the rare case that someone is traveling on a closed-loop cruise, meaning a trip that begins and ends at the same U.S.-based port, no passport or citizenship documentation is needed. Cruises that are one-way or have different departure and arrival ports do not qualify for this exemption, and U.S. citizens should be prepared with a passport, citizenship papers, enhanced driver's license or official proof of tribal status. Children under the age of 16 have the option of presenting an original or certified copy of their birth certificates, or other official proof of citizenship.

Land Travel Guidelines

The official stated policy for land travel to and from Mexico is that every U.S. citizen must present a valid U.S. passport card, passport book, trusted traveler card, driver's license, proof of tribal status, proof of military affiliation (with travel orders), or U.S. merchant mariner documentation (and proof of travel in conjunction with official business) to immigration officials at the border crossing.

Within Mexico Guidelines

While staying in Mexico, U.S. citizens rarely need a passport. However, some hotels request a passport for identification purposes. Likewise, cashiers may ask to see a passport when you are changing dollars or traveler's checks for pesos. In the event that you have special paperwork needs while in Mexico, such as work permits, tourist card extensions or bank documents for purchasing a house, a passport as well a current tourist or resident visa will be necessary.
