Before you plan to cross the border, make sure you understand the paperwork and identification you’ll need for your visit. Here is an overview of important guidelines:

Documents necessary to travel to Mexico

Passport and ID Requirements

The Western Hemisphere Travel Initiative requires all persons, including US citizens, who are traveling to and from the Americas, the Caribbean, and Bermuda to have a passport or other WHTI compliant document, such as a Passport Card (PASS Card), that establishes identity and citizenship to enter or re-enter the United States.

The approved documents include a passport, a passport card, a NEXUS, SENTRI or FAST trusted traveler program card, or a state- or province-issued enhanced driver’s license. Travelers under age 16 need to present only a birth certificate or alternative proof of citizenship.

What is a Passport Card/PASS Card?

Passport Cards (PASS Cards) are WHTI-compliant documents designed for US citizens who frequently cross the border via land and sea ports of entry in the United States, Mexico, Canada, and the Caribbean. PASS Cards cannot be used for air travel.

  • Firearms
