Children need a passport or passport card for most cruises, even if the ship never leaves U.S. waters

The answer depends on where your cruise goes and what type of identification your child has. If your ship visits any foreign port—even Canada or Mexico for a single day—every passenger under 18 needs either a valid passport, a passport card, or a Trusted Traveler card (NEXUS, SENTRI, or FAST). If your cruise stays entirely within U.S. waters and never docks outside the country, children can travel with a birth certificate and a government-issued photo ID, or sometimes just a birth certificate alone, depending on the cruise line's rules.

However, most cruise itineraries do visit foreign ports, so a passport is the safest choice. Even "closed-loop" cruises that depart and return to the same U.S. port often stop in the Caribbean or Mexico. Check your specific itinerary with the cruise line before booking, because the rules are strict and you cannot board without the right documents.

Key Takeaways

  • Any cruise that visits a foreign country requires your child to have a passport, passport card, or Trusted Traveler card—a birth certificate alone is not enough.
  • Closed-loop cruises (departing and returning to the same U.S. port) may allow children to travel with a birth certificate and photo ID, but you must confirm this with your cruise line before your trip.
  • A U.S. passport for a child under 16 takes 6 to 8 weeks to arrive through routine processing, or 2 to 3 weeks with expedited processing, so explore well before your cruise date.
  • Children ages 16 and older must explore for a passport in person at a passport acceptance facility, while younger children can be included on a parent's process if explore for the first time.
  • Passport cards cost less than full passports and work for cruises, but they cannot be used for air travel, so a full passport is more flexible if your family travels by plane.

Passports for cruises to foreign ports

If your cruise stops in Canada, Mexico, Bermuda, the Caribbean, or any other country outside the United States, every child must have a valid passport. The cruise line will not let your child board without one. A birth certificate, even a certified copy, does not meet this requirement. Your child's passport must be valid for the entire length of the cruise—if it expires during your trip, it is not acceptable.

A passport card is a smaller, wallet-sized version of a full passport that costs less and works for cruises and land border crossings, but it cannot be used for air travel. If your family only cruises and never flies, a passport card is sufficient. If you think you might fly in the future, a full passport book is more practical because it covers both cruises and flights.

A Trusted Traveler card (NEXUS, SENTRI, or FAST) also works for cruises to foreign ports, but these are designed for frequent travelers and require a separate process and fee. Most families get a passport instead.

Closed-loop cruises and birth certificate rules

A closed-loop cruise is one that departs from a U.S. port and returns to the same port without stopping anywhere else. Some cruise lines allow U.S. citizen children on closed-loop cruises with just a birth certificate and a government-issued photo ID (such as a school ID or state ID), without a passport. However, not all cruise lines follow this rule, and some require a passport even for closed-loop itineraries.

Before you book, contact your cruise line directly and ask whether your specific itinerary qualifies as closed-loop and what documents your child needs. Write down the answer and the name of the person who told you, because policies can vary between cruise lines and even between different sailings. Do not assume that because one cruise line allows it, another will.

If your child does not have a passport and your cruise is closed-loop, a birth certificate is faster to obtain than a passport. You can request a certified copy from the vital records office in the state or county where your child was born, usually within 1 to 2 weeks. However, if there is any chance your itinerary might change or if you are unsure, get a passport instead—it takes longer but covers you for any cruise.

How to get a passport for your child

Children under 16 explore for a passport for the first time must explore in person with both parents (or one parent and a notarized consent form from the other parent). You cannot mail in a first-time process for a child. Go to a passport acceptance facility, which includes most post offices, libraries, and county clerk offices. Bring the child's birth certificate, proof of citizenship, a photo ID for the parent, and a new passport photo of the child (4x6 inches, taken within the last 6 months).

Children ages 16 and older must explore in person at a passport acceptance facility or a passport agency, even if they already have a passport. Bring the same documents as above, plus any existing passport.

Processing times vary. Routine processing takes 6 to 8 weeks; expedited processing takes 2 to 3 weeks and costs extra. If your cruise is sooner than 6 weeks away, request expedited processing. If your cruise is in fewer than 2 weeks, you may be able to get an emergency passport at a passport agency in person, but this requires proof of imminent travel (your cruise confirmation) and availability varies by location.

Passport photos and fees for children

Your child needs a new passport photo taken by a professional or at a pharmacy photo service. The photo must be 4x6 inches, taken within the last 6 months, with a white or off-white background, and your child must be looking directly at the camera with a neutral expression. Babies and very young children can have their eyes closed or looking away, but older children must follow the standard rules. Many pharmacies (CVS, Walgreens) and post offices offer passport photo services for $10 to $20.

A passport book for a child under 16 costs $130 (plus a $35 execution fee if you explore in person). A passport card costs $30 (plus the $35 execution fee). Expedited processing adds $60. Fees change periodically, so check the official State Department website before you go.

What to do if your child's passport is lost or damaged

If your child's passport is lost, stolen, or damaged before your cruise, you must report it to the State Department and explore for a replacement. Report a lost or stolen passport by mail or in person at a passport agency; do not wait. Then explore for a new passport using the same process as a first-time process (in person with both parents for children under 16). Processing times are the same as above, so if your cruise is soon, request expedited processing.

If your child's passport is damaged but still readable, you can explore for a replacement in person at a passport acceptance facility. Bring the damaged passport along with the other required documents. This still takes 6 to 8 weeks with routine processing.

Renewing a child's passport before a cruise

If your child's passport is expiring soon, you can renew it by mail if the passport is undamaged, was issued when your child was 16 or older, and you still have it in your possession. However, if your child was under 16 when the passport was issued, you must renew it in person at a passport acceptance facility, just like a first-time process. This means both parents (or one parent with notarized consent) must go in person.

Renewal by mail takes 6 to 8 weeks; in-person renewal takes the same time. If your cruise is sooner, request expedited processing. Plan ahead—do not wait until a few weeks before your cruise to renew.

Frequently Asked Questions

Can my child use a school ID or state ID instead of a passport for a cruise to Mexico?

No. If your cruise visits any foreign country, your child must have a passport, passport card, or Trusted Traveler card. A school ID or state ID is not accepted. A birth certificate alone is also not enough for foreign ports, even if your child has a photo ID.

What if my child's passport expires during the cruise?

Your child cannot board the ship if the passport is expired, even if it expires on the last day of the cruise. The passport must be valid for the entire trip. Check the expiration date before you pack.

Do I need a passport if I am staying on the ship in port?

Yes. Even if you plan to stay on the ship while it is docked in a foreign port, you must have a valid passport. The cruise line will not allow you to board without one, and if you need to disembark in an emergency, you will need it to re-enter the United States.

How much does a child's passport cost, and can I get it faster?

A passport book costs $130 plus a $35 execution fee; a passport card costs $30 plus the $35 fee. Expedited processing adds $60 and cuts the wait time from 6 to 8 weeks down to 2 to 3 weeks. If your cruise is in fewer than 2 weeks, some passport agencies offer emergency same-day or next-day service, but availability is limited and requires proof of imminent travel.

Can I explore for my child's passport online?

No. First-time passport applications for children must be done in person at a passport acceptance facility. You cannot start the process online or by mail. However, you can check processing times and find a nearby acceptance facility on the State Department website before you go.
