Mexico Entry Requirements for Cancun (2026): Passport, Digital FMM, Customs & VISITAX

Mexico’s entry requirements for a Cancún vacation are simple: US and Canadian citizens need a valid passport book and no visa for a tourist stay of up to 180 days. At Cancún International Airport (CUN) the old paper tourist card is gone. An immigration officer, or a self-service e-gate, records your entry digitally, decides how many days you get, and issues a receipt with a QR code that leads to your digital FMM. Keep it until you fly home. You then clear customs, where air passengers have a duty-free allowance of up to US$500 on top of personal luggage. Quintana Roo also charges every foreign visitor a one-time VISITAX of about 285 MXN, paid on visitax.gob.mx.

This guide covers each step in the order you meet it: documents to pack, immigration at CUN, customs, VISITAX, children, and coming home to the US or Canada. We checked it against Mexican government sources (the National Migration Institute, INM, Mexican consulates and the customs rules published by the SAT) plus US and Canadian government pages as of October 2026. Entry rules change with little notice, so check before you fly.

Mexico Entry Requirements for Cancún at a Glance (2026)

Passport Rules: How Long Must It Be Valid?

Mexico’s own rule is that your passport must be valid when you arrive and for the whole of your stay. The Government of Canada puts it the same way, and Mexican consulates say the same. There is no formal six-month rule for visitors, but there are three good reasons to have that much validity anyway:

• Airlines can apply stricter rules than the country you are flying to, and a check-in agent who is unsure can refuse to board you.
• The self-service e-gates at CUN only accept e-passports with more than 180 days of validity (see below).
• Delays happen. A cancelled flight or a hurricane can stretch your trip by days, and you need a valid passport to fly home.

Americans flying to Cancún need a passport book. The US passport card is not valid for international air travel, so it won’t get you on a plane to Mexico or home again. Canadians need a regular Canadian passport. Make sure the name on your ticket matches your passport exactly.

Do I need a visa for Cancún?

Citizens of the US, Canada, the UK and the EU do not need a visa for tourism. Many other nationalities do. Mexican consulates say that travelers who would otherwise need a visa can usually enter without one if they hold a valid visa, or permanent residence, from the US, Canada, the UK, Japan or a Schengen country. They must show it together with their passport. An expired US visa or a work permit card does not count. If this applies to you, confirm with the Mexican consulate that serves your area before you book.

The Digital FMM: How Immigration Works at Cancún Airport

The FMM (Forma Migratoria Múltiple) is Mexico’s tourist permit. For air arrivals it is now digital, the FMMD. You no longer fill in a paper card on the plane, and you don’t need to apply online before you fly. Here is what happens after you land at Terminal 3 or Terminal 4:

• Officer booth: hand over your passport. The officer may ask why you are visiting, where you are staying and when you leave. They record your entry and stamp or print your authorized stay.
• E-gates (Filtros Migratorios Autónomos): CUN has self-service gates in Terminals 3 and 4. According to Mexico’s consulates, you can use them only if you are 18 or older, hold an ordinary e-passport from an eligible country (the US and Canada are on the list) with more than 180 days of validity, are visiting purely for tourism and are not traveling with minors. You scan your passport, the gate takes a photo, and it prints a ticket with a QR code and a digital stamp.
• Download your FMMD: scan the QR code on your receipt or ticket to download the digital FMM as a PDF. You don’t have to do it at the airport, but older consular notices give a deadline of 60 days from entry. Do it at the hotel on day one and save a copy offline.

The fee for a tourist permit is normally included in the taxes on your plane ticket, so there is nothing to pay at the airport. If anyone at the arrivals hall asks you to pay for an “FMM” or a “tourist card,” it isn’t official. That hall is also where timeshare and transfer touts work; our Cancún airport guide to Terminals 2, 3 and 4 shows the layout.

What the officer may ask to see

Mexican consulates list a printed return ticket and hotel booking as recommended documents, not formal requirements, and holding a visa or a passport never guarantees entry: the final decision belongs to the officer. Questions are usually brief for vacationers, but have these ready on your phone and, ideally, on paper:

• Return or onward flight confirmation.
• Hotel or resort confirmation with the address. If you are still choosing, our best all-inclusive resorts in Cancún list is a good place to start.
• A rough idea of your plans (for example, “a week at the resort and a day trip to Chichén Itzá”).

Mexican Customs: Allowances and What Not to Pack

After baggage claim you go through customs, run by the national customs agency (ANAM). The general foreign trade rules published by the SAT set the limits for travelers. Your personal luggage (clothes, toiletries, used personal items) enters free. On top of that, each passenger has a duty-free allowance (franquicia) for other goods worth up to US$500. Alcohol and tobacco have separate limits and can’t be counted toward the US$500.

Things that cause trouble at Mexican customs:

• Vapes and e-cigarettes. Mexico bans vaping devices, and a legal reform in force since January 2026 makes bringing them into the country an offense. Travelers have reported confiscations and fines, so leave them at home.
• Prescription medicines. Bring only what you need, in the original labeled packaging, with a copy of the prescription. This matters most for strong painkillers, sleeping pills and ADHD medication. If you run out, our Cancún pharmacy guide explains which chains to trust.
• Fresh food, plants and meat. These are subject to agricultural inspection. Don’t pack fruit or sandwiches from home.
• Firearms and ammunition, including a single stray bullet in a bag. Mexican penalties are severe.

Our Cancún all-inclusive packing list covers what is worth bringing. If you have goods to declare, use the declaration channel. Otherwise you put your bags through the X-ray and walk out to the arrivals hall.

VISITAX: The Quintana Roo Visitor Fee

VISITAX is a one-time state fee of about 285 MXN (roughly US$15–17) per foreign visitor to Quintana Roo, the state that includes Cancún, Playa del Carmen and Tulum. It is separate from immigration and customs, and you pay it only on the official portal, visitax.gob.mx. Look-alike sites charge extra for the same receipt. Exemptions (for example, for certain residents) change from time to time, so check the portal rather than relying on a forum post. Save the receipt on your phone, because you may be asked for it when you leave.

VISITAX is not the only local charge. Hotels add the Cancún environmental sanitation fee of about 82 MXN per room per night at check-in, and room rates carry 16% IVA plus 5% state lodging tax. Our guide to Cancún resort taxes, VISITAX and tipping explains every line.

Traveling to Cancún with Children: Passports and Consent Letters

Every child, babies included, needs their own passport to fly to Mexico. For the consent letter question, Mexico’s rule depends on the child’s nationality:

• Foreign children visiting as tourists (for example, US or Canadian citizens with no Mexican nationality) do not need a Mexican authorization or consent letter to enter or leave Mexico, according to Mexican consulates.
• Children who are Mexican citizens or Mexican residents, including dual US–Mexican or Canadian–Mexican nationals, are treated as Mexican. If they leave Mexico alone or with only one parent or another adult, they need the INM’s minor departure form (SAM) or a notarized consent from both parents. If your child was born to a Mexican parent, plan for this before the return flight.

Your own country may still want a letter. US Customs and Border Protection recommends that an adult traveling with a child carry a note from the absent parent, and Canada strongly recommends a consent letter whenever a Canadian child travels without both parents. Airlines can ask for one too. A signed letter with the other parent’s contact details costs nothing and can save a tense conversation. Also remember that minors can’t use the e-gates, so families go to the officer booths. For resorts built around kids, see our best Cancún family resorts with waterparks.

Leaving Mexico and Returning to the US or Canada

Leaving Cancún by air is easy. There is no separate exit form for tourists; your airline’s passenger data records the departure. Keep your FMMD receipt or PDF handy, because Canada’s travel advice notes you may be asked to show it when departing. Arrive at CUN with plenty of time, as security and check-in lines get long on Saturdays and holidays. Our Cancún airport transfers guide explains how long the drive from your hotel takes.

Requirements for getting home, in general terms:

• US citizens must show a valid passport book to re-enter the US by air. US Customs and Border Protection gives returning residents an US$800 duty-free personal exemption, and one liter of alcohol (age 21+) is duty-free; above that, some items are dutiable and states can set their own alcohol limits. Declare all food. Cuban cigars, counterfeit goods and some medicines are restricted.
• Canadians need a valid Canadian passport. Personal exemptions depend on how long you have been away, and there are separate alcohol and tobacco limits. Check the Canada Border Services Agency before you shop.

If you plan to bring home tequila, silver or crafts, our Mercado 28 souvenir guide has tips on buying genuine silver and packing bottles.

Pre-Trip Checklist

• Passport book for every traveler, valid for the whole trip (ideally 6+ months).
• Visa or qualifying US/Canada/UK/Japan/Schengen visa or residence, if your nationality needs one.
• Return flight and hotel confirmations, saved offline.
• VISITAX paid on visitax.gob.mx, receipt saved.
• Consent letter if a child is traveling without both parents; SAM form if the child is Mexican.

Frequently Asked Questions

Do I need a passport to go to Cancún?

Yes. Everyone flying from the US or Canada to Cancún needs a passport book, children and babies included. A US passport card, a driver’s license or a birth certificate is not enough for international air travel.

Does my passport need 6 months of validity for Mexico?

Mexico requires a passport valid for your whole stay, not six months. But the e-gates at Cancún airport need more than 180 days of validity, and airlines can be stricter, so six months of spare validity is the safe choice.

Do I still need to fill out an FMM tourist card for Cancún?

Not on paper. For air arrivals the FMM is digital and created at immigration in Cancún. Keep the QR receipt or ticket you are given, download the PDF soon after arrival, and keep it until you leave Mexico.

Is VISITAX mandatory in Cancún?

Yes, for foreign visitors to Quintana Roo. It costs about 285 MXN per person, once per trip, and should be paid only on visitax.gob.mx. Check the portal for current exemptions.

Does a child traveling with one parent need a consent letter for Mexico?

Mexico does not require one for foreign children visiting as tourists, but it does for Mexican-citizen or resident children leaving the country. The US and Canada recommend carrying a signed letter from the absent parent in every case, and airlines may ask for it.

How much cash can I bring into Mexico?

There is no limit, but you must declare cash and monetary instruments over US$10,000 (or the equivalent) when entering or leaving Mexico. Not declaring it can lead to confiscation or detention.
