  • U.S. passport - This is the internationally recognized travel document that verifies a person's identity and nationality, accepted for travel by air, land and sea.
  • U.S. passport card - This new, limited-use travel document fits into your wallet and costs less than a passport, but is only valid for travel by land and sea.
  • Enhanced driver's license - Several states and Canadian provinces are issuing special drivers licenses that denote both identity and citizenship specifically for cross-border travel by land or sea. Check Web site below for issuing states.
  • Trusted traveler program cards - Enrollment cards from the NEXUS, SENTRI or FAST programs are issued to approved, low-risk travelers for travel by land or sea or to airports with a NEXUS kiosk.
  • U.S. and Canadian citizen children under the age of 16 may also present an original or copy of a birth certificate, a Consular Report of Birth Abroad, a Naturalization Certificate, or a Canadian Citizenship Card.
  • U.S. lawful permanent residents document requirements have not changed - present a permanent resident card (Form I-551) or other valid evidence of permanent residence status.

Items allowed back to the United States:

  • U.S. residents must declare purchases when re-entering the country, even from a day trip to Mexico.
  • If you have not used your duty-free exemption in the past 30 days, you may bring back $800 worth of items for your personal or household use, including - if you're 21 -- not more than one carton of cigarettes and 100 non-Cuban cigars and one liter of alcohol.
  • If you have used any part of your duty-free exemption within 30 days, different rules apply. If in doubt, ask U.S. border officials before you cross and buy more.
  • Prescription drugs:
  • As a matter of law, U.S. law prohibits "importation" of prescription drugs from outside the United States. But as a matter of enforcement, an exception is generally made for declared purchases of FDA-approved drugs in amounts reasonable for "personal use" (usually a 60 to 90-day supply).
  • If your prescription contains a narcotic or other controlled substance, you may need a prescription from a Mexican doctor to purchase it - and one from a U.S. doctor to bring it back across the border. For details, visit the U.S. Food and Drug Administration website and the U.S. Customs and Border Control website.
  • There are risks associated with buying drugs in Mexico. Before you do, talk to your doctor and do some homework to find out how to minimize those risks.
