Cruise Documents Checklist
Passport or birth certificate? What U.S. citizens need, and everything else to carry.
Get Free Cruise QuotesDocuments are the one part of cruise preparation where a mistake can stop you sailing. Requirements depend on your citizenship, where the cruise starts and ends, and the countries it visits. This checklist is for U.S. citizens; everyone else should check with their cruise line and the countries on the itinerary.
Always confirm with official sources and your cruise line. Rules change, and cruise lines can require more than the government does. Official guidance: U.S. Customs and Border Protection (WHTI) and the U.S. State Department’s cruise ship page.
Passport or Not? U.S. Citizens
| Type of cruise | What is generally accepted for U.S. citizens | Notes |
|---|---|---|
| Closed-loop: starts and ends at the same U.S. port | A passport, or an original or certified birth certificate plus a government-issued photo ID (CBP) | Countries you visit may still require a passport. Children under 16 generally need only proof of citizenship such as a birth certificate; confirm with your line. |
| Starts or ends in a foreign port, or one-way between different U.S. ports | Passport book | One-way sailings are not closed-loop, even when both ports are in the U.S. |
| Any itinerary | Passport book recommended | The State Department notes that you need a passport book to fly home from abroad if you must leave the ship early because of illness, injury or a change of plans. |
A passport card is valid for re-entering the U.S. by sea from Mexico, Canada, Bermuda and the Caribbean, but it cannot be used to fly internationally. If there’s any chance you’d need to fly home from a foreign port, a passport book is the safer choice.
The Documents Checklist
- Passport book (check the expiry date — many travelers aim for at least six months beyond the trip, and some countries require it) or original/certified birth certificate plus government-issued photo ID for closed-loop cruises
- Names on your booking match your ID exactly
- Any visas required by countries on the itinerary (rare for U.S. citizens on Caribbean cruises; check for others)
- Cruise boarding pass and luggage tags from online check-in
- For minors traveling without both parents: a notarized letter of consent, plus any court or custody papers; many lines require this
- Marriage certificate or court document if your ID name differs from your birth certificate
- Travel insurance policy and emergency phone numbers
- Credit card for your onboard account, plus a small amount of cash for porters and ports
- Health insurance card and a list of medications and allergies
- Photocopies or secure digital copies of everything, stored separately from the originals
Flying to Your Ship? REAL ID
If you are flying to your departure port, airport rules apply before cruise rules. Since May 7, 2025, TSA requires a REAL ID-compliant driver’s license or another acceptable form of ID, such as a passport, to board domestic flights. Check your license for the REAL ID star and see TSA’s REAL ID page for the current list of acceptable IDs.
Where to Keep Documents
- In your carry-on or on your person — never in checked luggage.
- In one waterproof folder, so check-in is quick.
- In the cabin safe once aboard; take only what you need ashore.
