What Documents Do You Need for a Cruise? A Complete Checklist

Cruises involve international travel, so you can’t board without the right documents and ID. This guide explains what cruise documents are, which ones you need, and how to get them, plus a few extra items worth packing just in case, so your embarkation day goes smoothly.

What Are Cruise Documents?

Cruise documents are the identification and paperwork you must present at the port before you’re allowed to board. At a minimum, you’ll need an acceptable form of official ID and your boarding pass. If your itinerary includes countries that require visas, you’ll need those too. Port officials will check and verify each document at the terminal, and only then will you be permitted to board.

Digital vs. printed copies

Many cruise lines now offer online boarding passes. Take a screenshot or add yours to your phone’s wallet so it’s easy to pull up. With nearly every traveler carrying a smartphone, and eco-friendliness top of mind, it’s tempting to keep everything in an app and skip the paper.

But what happens if your phone is lost, stolen, or broken mid-trip? That’s why I always recommend printing hard copies of anything you might need in a pinch. Use as little paper as you can, but remember: it’s better to be safe than sorry.

Keep everything in your carry-on

Always pack your travel documents in your carry-on bag, in a spot that’s easy to reach. Do the same with medications and valuables such as jewelry, car keys, and glasses. Your checked luggage may not reach your cabin until hours after you board, so keep anything essential with you.

Documents Needed to Board a Cruise Ship

Passport book (most cruises)

For most sailings, you’ll need a passport book that’s valid for at least six months after the day your cruise ends. A passport card may work in some cases, but only if you’re re-entering the U.S. by ship from Mexico, Canada, Bermuda, or the Caribbean.

Closed-loop cruises

A closed-loop cruise begins and ends at the same U.S. port and visits destinations such as Mexico, Canada, Bermuda, and the Caribbean. On these itineraries, U.S. Customs & Border Protection allows U.S. citizens to board without a passport book if they have one of the following:

Travelers under 16

Minors can use an original, notarized, or certified copy of their birth certificate, a Consular Report of Birth Abroad, or a Certificate of Naturalization. Voter registration cards, Social Security cards, and school IDs are not accepted as proof of citizenship.

U.S. permanent residents

You must carry your green card. It can be used instead of a passport on closed-loop sailings, but carrying a passport from your country of citizenship is strongly recommended. An expired green card could prevent you from re-entering the U.S. You’re also responsible for contacting the embassies of the countries you’ll visit to check whether additional paperwork is required.

Risks of Sailing Without a Passport

Traveling without a passport is allowed on closed-loop cruises, but keep two risks in mind:

How to Get a Passport

U.S. citizens can apply through the State Department: travel.state.gov/passports. Apply at least six months before your departure date.

Travelers from other countries should apply through their own government’s official passport office, typically found on the national foreign affairs or immigration website, and should check processing times early, since they vary widely by country.

Boarding Passes

Just like a flight, a cruise boarding pass shows that you’ve checked in for your sailing, set up an onboard account for purchases, and chosen a boarding time. It also includes key details such as your name, booking number, cabin number, and any packages you’ve booked, like a beverage package.

Most cruise lines now offer mobile apps that let you check in before you arrive at the terminal. If you don’t plan to use the app, bring a printed copy of your boarding pass. Having one on hand will speed up check-in on embarkation day.

If you arrive without a boarding pass, don’t panic. Port staff can look up your reservation in the system, though it may add some extra time before you’re able to board and start your vacation.

Health Information

For many years, cruise lines have required passengers to complete a health questionnaire before boarding to help prevent the spread of norovirus on board. This used to be a paper form filled out at the terminal during check-in. Today, most cruise lines let you complete it online through their mobile app, typically about 24 hours before embarkation. It’s just a few simple questions asking whether you’ve had any symptoms of illness and whether you’re more than 23 weeks pregnant.

COVID-19 requirements

Vaccinations for specific destinations

Also check whether any of the ports on your itinerary require specific vaccinations for entry. If they do, carry proof that you’ve received them.

Visas and Other Destination-Specific Documents

Some destinations require a visa or other authorization before you can enter and stay. It’s your responsibility to find out whether you need one, what it costs, and how much processing time to allow.

Occasionally, a cruise line will handle visas for passengers and cover the fees. Check the official government websites for each country on your itinerary, then contact your cruise line to ask whether they apply on your behalf. Keep every required document with you during your trip. Online cruise forums are another good source of real-world advice, so search Facebook for a group for your specific ship or cruise line.

United Kingdom (UK ETA)

If you’re boarding in the UK or stopping at a UK port, get your UK Electronic Travel Authorisation (ETA) before you leave home. Since 8 January 2025, eligible non-European visitors, including travelers from the USA, Canada, and Australia, have needed an ETA to travel to the UK.

Europe (ETIAS)

Many European countries will eventually require travelers from visa-exempt countries to hold an ETIAS authorization. According to a recent report, the EU’s official portal confirms the system is not yet in operation and that a start date will be announced months in advance. Check the official ETIAS website and your cruise line before you sail.

United States (ESTA)

Visitors from visa-waiver countries traveling to the U.S. generally need approval through the Electronic System for Travel Authorization (ESTA). Use the official government site to apply and confirm whether you need it.

Canada (eTA)

The Government of Canada’s official website lets you apply for an electronic travel authorization (eTA), which is required for most visa-exempt travelers who fly to or transit through a Canadian airport. It costs CAN$7, and the site will tell you whether you need one. At the time of writing, U.S. citizens do not.

Cruise Line Luggage Tags

When you arrive at the port, you can drop your luggage with porters, who will make sure it gets loaded onto the ship. Print the paper luggage tags your cruise line provides with your check-in documents. They come prefilled with details like your name and cabin number, so the crew knows exactly where to deliver your bags.

We’ve started using luggage tag holders after having tags accidentally torn off during loading. The ones we use are made for Royal Caribbean and Celebrity ships, and holders for other cruise lines are available too.If you’re driving to the port, you can attach the tags before you leave home.

If you’re flying, wait until you land to attach them so airline baggage handlers don’t remove them.

If you arrive without your tags, don’t panic. Porters keep blank tags on hand and will fill them out and attach them for you.

Permission to Travel

Pregnancy

If you’re pregnant, you must tell your cruise line. Some lines also require a note from your doctor confirming your due date and that you’re fit to travel. Most cruise lines will not let you sail if you will be 24 weeks pregnant or more at any point during the voyage, so check your cruise line’s policy before booking.

Traveling with children who aren’t yours

If you’re taking someone else’s children on a cruise without a parent or guardian, you’ll need a notarized letter that authorizes you to take them out of the country and consent to medical care on their behalf in an emergency. If you can’t get a notarized letter from the child’s parent or parents, bring court-issued documents granting you custody.

Traveling alone with your own children

It’s also smart to carry a similar letter if you’re traveling alone with your own kids and their last name doesn’t match yours. Cruise lines and airlines are increasingly cracking down on child trafficking, so having the right paperwork on hand is more important than ever.

Quick note: Requirements vary by cruise line and destination, so it’s worth adding a line encouraging readers to confirm with their cruise line before sailing. If you have sole custody, the court order alone may be enough, but a consent letter is still a good backup if the other parent is reachable.

Useful Information to Carry While Cruising

Beyond the documents you need to board, a few extra items can save you time and stress during your trip.

Copies of important documents

Protect your personal documents by taking only what you need. Before you leave, make copies of:

Store the copies in a safe place, separate from the originals. You can also photograph them and keep the images in a separate, secure spot on your phone, such as a password-protected folder or cloud account. Copies won’t replace the real thing, but they can speed up the process if you need to arrange replacements.

When you’re in your hotel room or cruise cabin, lock your documents in the safe.

Heads up on passports: In some countries, the ship will hold onto passengers’ passports so local authorities can check them before anyone disembarks. If that happens, the ship will give you a receipt, which you’ll need to get your passport back, so keep it somewhere secure.

To keep everything organized, a travel document holder is a handy way to store your important papers in one place.

Emergency contacts

Carry a list of emergency contacts, including someone at home who has a copy of your itinerary. Also write down your cruise line’s emergency number and the contact information for your ship’s port agent.

Travel insurance details

Bring your policy number and the insurer’s 24-hour assistance line. If you need medical care or have to leave the ship early, you’ll want that information handy.

Medical information

Carry a list of your medications (including dosages), allergies, and health conditions, along with your doctor’s contact details. Keep prescriptions in their original packaging, and bring a doctor’s note for anything that could raise questions at customs.

Cruise line and itinerary details

Save your ship’s name, your cabin number, your port schedule, and the “all aboard” time for each stop. Missing the ship is a real risk, so know exactly when you need to be back.

Some cash and a backup payment method

Bring a small amount of local currency for ports and tips, plus a second credit or debit card in case one is lost or declined. Let your bank know about your travel dates so your cards aren’t frozen.

Flying to the Cruise Port?

If you’re a U.S. citizen flying to your embarkation port, make sure your ID is airport-ready. Since May 7, 2025, state-issued driver’s licenses and IDs that aren’t REAL ID compliant are no longer accepted on their own as identification for domestic flights. You’ll need either an acceptable alternative, such as a passport, or a REAL ID from your state DMV (look for the star on your license).

Since February 1, 2026, adults without a REAL ID or accepted alternative must pay a non-refundable $45 fee to verify their identity through TSA’s system, and payment doesn’t guarantee approval, so travelers whose identity can’t be confirmed may be denied entry at the checkpoint. You don’t want an ID issue to be the reason you miss the ship!

The good news: a REAL ID is not required to board the cruise ship itself. It only applies to your flight. (Be sure to bring the cruise ID documents covered earlier in this post as well.)

For more details, see our REAL ID Requirements: Your Travel Checklist.

Final Thoughts

Cruise documents are what verify your right to board on embarkation day. They include your identification, boarding pass, health forms, and any required visas or travel authorizations. Keep them all in your carry-on bag or personal item so they’re within easy reach.

There are several documents to keep track of, but if you plan ahead and work through the checklist above, you’ll be ready for a smooth, stress-free boarding experience.

Have a wonderful cruise!
