Passport or birth certificate for a San Diego cruise

Most cruises from San Diego start and end here, and on those, U.S. citizens can usually sail without a passport. The exceptions are the one-way trips, such as the spring runs up the coast to Vancouver, the Panama Canal crossings that end in Florida or Texas, and the long voyages to South America.

This guide is for U.S. citizens. Each line makes the final call, so check its own page before you rely on a birth certificate.

Round trips and the birth certificate rule

U.S. Customs and Border Protection's rule covers what it calls closed-loop cruises, ones that start and end at the same U.S. port. On those, U.S. citizens can re-enter the country with a birth certificate and a government-issued photo ID. CBP adds that the countries the ship visits may still ask for a passport.

The three lines with the most San Diego sailings all accept that combination on round trips, with their own conditions:

Line	Birth certificate	Also need	Not accepted
Disney	Original state-issued	A physical government photo ID	Hospital certificates, digital or mobile IDs
Royal Caribbean	Original, state-certified	A government photo ID	Photocopies, hospital or "baby feet" certificates
Holland America	Original or certified copy	A U.S. government photo ID

Disney and Royal Caribbean don't ask children 15 and under for a photo ID. CBP says children under 16 need only a birth certificate.

The port says passports, the lines don't

The Port of San Diego's own pages say passports are required for Mexico cruises. CBP, Disney, Royal Caribbean and Holland America all accept a birth certificate and photo ID for U.S. citizens on a round trip. We go by the lines, since they decide who boards. Still, the lines lean the port's way too. Disney encourages every U.S. guest to carry a passport, and Royal Caribbean recommends one.

There's a practical reason too. CBP notes that anyone flying internationally needs a passport, children included. If you had to leave the cruise in Mexico and fly home, a birth certificate wouldn't get you on the plane.

Most one-way trips need a passport

A cruise that ends somewhere other than San Diego isn't a closed loop. The lines are clear about these:

• Royal Caribbean requires a passport book for one-way sailings, including the Panama Canal, valid at least six months after the cruise ends.
• Disney requires a passport valid six months after the sailing for Panama Canal cruises. For its one-way Pacific Coast sailings to Vancouver, it accepts a passport, a passport card or a NEXUS or FAST card if you travel home by land or sea, and a passport if you fly.
• Holland America requires a passport valid six months past the end of the trip for voyages that end outside the United States.

On our schedule, Disney's one-way sailings from San Diego are Disney Magic's Panama Canal trips on November 6, 2026 and November 4, 2027, both ending in Galveston, and the 4-night runs to Vancouver on May 6 and May 9, 2027 and May 4, 2028. Disney's own page names Canada Place as the Vancouver terminal. The schedule marks every one-way trip with the port where it ends.

Mexico

Nearly every round trip from San Diego calls in Mexico, usually at Ensenada. Mexico's immigration rules give cruise passengers on the ship's manifest a collective permit, issued at the first Mexican port, for a stay of up to 21 days. The rules deal with that separately from the individual tourist permit, the FMM.

REAL ID on its own isn't enough

Since May 2025 you need a REAL ID or another accepted ID, such as a passport, to board a domestic flight. On its own, a REAL ID isn't a travel document for a cruise. TSA says a REAL ID card can't be used for international sea travel, and Holland America says a REAL ID isn't a border-crossing document. A driver's license still counts as the photo ID that goes with a birth certificate on a round trip.

An enhanced driver's license is different. CBP accepts one at land and sea borders, and Royal Caribbean accepts one on round trips. TSA lists five states that issue them: Michigan, Minnesota, New York, Vermont and Washington. One Holland America page lists four, leaving out Minnesota.

A few rules that catch people out

• Holland America requires a passport for everyone when minors travel with only one adult.
• Royal Caribbean requires a notarized consent form from the child's guardian when a minor sails without them.
• Holland America says the names on your ID must match your booking exactly.
• Disney doesn't accept a Social Security card or a Global Entry card as proof of citizenship.
• Green card holders should check their line's page. Disney asks for the original Permanent Resident Card, plus a passport on its one-way Canada sailings, and Holland America recommends carrying a passport as well.

Bring the documents with you to the terminal, not in checked bags. The port asks for photo ID, your boarding document and your passport or birth certificate at the door. The terminals guide covers the rest of embarkation day.
