CUN airport code: IATA, ICAO, terminals and traveler information
CUN is the IATA code for Cancún International Airport. The airport’s ICAO identifier is MMUN, and CUN is the main air gateway used by travelers heading to Cancún and much of the Riviera Maya.
What is the CUN airport code?
CUN is the three-letter IATA airport code for Cancún International Airport in Quintana Roo, Mexico. It is the code normally shown in passenger flight searches, airline itineraries, boarding passes, airport displays and checked-baggage routing.
The airport’s four-letter ICAO identifier is MMUN. Most leisure and business travelers do not need to type MMUN when booking a normal airline trip.
Airport live checks & travel tools
Use current local conditions, official live-status links and planning calculators before you travel. Airline gate, terminal and flight times can change; your carrier remains the final source for flight-specific details.
Live flight center
Check the airport's official flight board, then confirm any last-minute gate or timing change with the airline.
Current airport-area weather
Useful for planning your trip to the airport. This is model-based local weather, not an aviation METAR or an airline operational forecast.
Quick official checks
Open the source that matches the decision you are making right now.
When should I reach the airport?
A planning estimate based on flight type and common time buffers. Always increase the buffer for severe weather, major holidays, unusual airport alerts or airline instructions.
Connection-risk checker
This is a planning heuristic, not an airline minimum-connection-time rule. International arrivals that require U.S. entry processing, baggage claim and security can need substantially more time.
Parking cost estimator
Uses the airport-specific rates stored in this article's configuration. Rates can change; verify availability and final pricing on the official parking page before driving in.
Passenger pickup readiness
Landing time is not curb-ready time. Add time for taxiing, deplaning, baggage claim, customs when applicable and walking to the correct pickup zone.
CUN, MMUN and common Cancún code confusion
Different travel and aviation systems can show different identifiers for the same airport. The quickest way to avoid mistakes is to match the code to the task you are completing.
| Term | Meaning | Traveler use | What to do |
|---|---|---|---|
| CUN | IATA code for Cancún International Airport | Flights, tickets, baggage and transfers | Use this for normal passenger travel |
| MMUN | ICAO airport identifier | Aviation, operational and aeronautical data | Do not substitute it for CUN in most booking forms |
| CAN | Not Cancún | A different airport code | Do not use CAN when booking Cancún |
| Cancún shuttle code | Usually a transfer-company question, not a separate official airport code | Hotel or airport transfer booking | Provide CUN plus flight and terminal details |
| Postal code | Address field, not an airport identifier | Forms and deliveries | Use the exact address requested by the company or form |
Cancún Airport terminals: T1, T2, T3 and T4 explained
Cancún has a multi-terminal layout. The terminal matters for check-in, meeting a driver, finding the correct arrivals curb and planning a connection, so do not use the airport code as a substitute for the terminal number.
Terminal 1
The previous terminal had remained closed while reconstruction and expansion work progressed. The latest verified 2026 management update points to a planned Q4 2026 opening.
Traveler action: do not go to T1 unless your airline or current airport information specifically directs you there.
Terminal 2
T2 remains part of the airport’s active passenger complex. ASUR currently lists food, shopping, banking, baggage wrapping and ADO ground transport in or from this terminal.
Traveler action: verify your individual flight rather than relying on a permanent airline list.
Terminal 3
T3 supports substantial international passenger activity. ASUR lists restaurants, retail, lounges, communications services and ADO transport here.
Mexico’s INM also lists autonomous immigration filters for eligible arriving passengers in T3.
Terminal 4
T4 is another major passenger terminal with restaurants, food courts, duty-free retail, banking/ATM services, lounges and ADO transport listed by ASUR.
INM autonomous immigration filters are also listed in T4 for eligible travelers.
How to confirm your CUN terminal before leaving
Find the operating airline
A codeshare itinerary can show the marketing airline prominently even when another carrier operates the aircraft. Use the operating carrier for final flight-specific checks.
Check the latest itinerary or airline app
Look for the current airport terminal beside CUN. Do not assume the terminal is unchanged because you previously flew the same route.
Cross-check close to departure
Use ASUR’s airport information and your airline before you start the trip. Construction and operational changes can make an old screenshot unreliable.
Share the terminal with your driver
If someone is collecting you, send the full flight number and terminal instead of simply writing “Cancún Airport.”
CUN departure process: a practical sequence
Your exact departure flow depends on airline, destination, checked baggage and travel documents. This sequence helps you identify the decisions that matter without assuming every traveler follows an identical path.
Confirm CUN and the correct terminal
Check the operating airline, scheduled departure and terminal before setting out for the airport.
Prepare airline and destination documents
Keep your passport or acceptable travel identification, boarding information and any entry documents required by the country you are flying to accessible.
Complete airline check-in and baggage drop
If you have checked bags or need document verification, follow the operating airline’s counter and baggage-drop instructions.
Pass airport security
CUN is in Mexico, so Mexican airport-security procedures apply. Do not assume U.S.-specific screening programs determine the process here.
Recheck the gate
The airport code and terminal may be correct while the boarding gate still changes. Follow the airline and airport displays after security.
International arrival process at CUN
An international arrival normally involves immigration processing before you complete the remaining arrival formalities. The exact sequence can vary with terminal, nationality, baggage and instructions given by Mexican authorities.
Follow signs for immigration
Have your passport and relevant entry documentation ready. Travelers eligible for INM’s autonomous filters may see a separate FMA route in Terminals 3 or 4.
Collect checked baggage
Use the carousel assigned to your flight. If a checked bag does not appear or arrives damaged, report it to your airline’s baggage service before leaving the controlled arrivals process whenever possible.
Complete customs requirements
Mexico’s customs rules apply to goods you bring into the country. Declare items when required and ask customs staff when you are unsure rather than guessing.
Enter the public arrivals area
Once you have completed the required arrival formalities, follow the terminal signs to your authorized taxi, ADO service, rental-car arrangement or pre-booked transfer meeting point.
CUN autonomous immigration filters in Terminals 3 and 4
Mexico’s Instituto Nacional de Migración lists Filtros Migratorios Autónomos (FMA) at Cancún Airport Terminals 3 and 4. These are self-service immigration filters, not a universal replacement for the staffed immigration process.
Current basic eligibility
- An ordinary electronic passport.
- Passport validity of more than 180 days for FMA use.
- Age 18 or older.
- Entry to Mexico exclusively for tourism.
- No accompanying minor through the FMA process.
- Nationality included in INM’s current eligible list.
Travelers who may need the traditional process
INM says FMA is not for several non-tourist categories, including certain student, employment, family-unity, humanitarian and Mexican temporary/permanent residence cases, or travelers using diplomatic, official or service passports.
Travelers with minors should use the traditional immigration filters rather than taking the minor through FMA.
FMA ticket and Forma Migratoria Múltiple Digital
After successful FMA processing, INM says the system provides a ticket containing a QR code and digital entry information. Foreign travelers using this process should keep the ticket and follow the QR route for their digital immigration form.
Keep the FMA ticket
Do not discard it after leaving the immigration area. INM says the ticket may be requested when you leave Mexico.
Scan the QR code
Use a phone camera or compatible QR reader to open the immigration-entry record.
Review and download the FMMD
INM says foreign travelers have up to 90 calendar days from entry to download their Forma Migratoria Múltiple Digital after entering through FMA.
Keep the digital record accessible
Save the file where it can be retrieved during your trip rather than relying only on a browser tab.
Mexico customs at CUN: baggage and passenger franchise
After international arrival, passengers may need to complete Mexican customs formalities. The National Customs Agency of Mexico distinguishes personal baggage from the separate passenger franchise for additional merchandise.
Current passenger franchise
ANAM’s current Aduana Fácil guidance states that passengers may bring merchandise worth up to US$500, or the equivalent in another currency, under the passenger franchise in addition to qualifying personal baggage.
The rule currently applies regardless of whether the passenger enters Mexico by land, air or sea.
Traveling as a family
ANAM says family members’ franchises can be combined when they arrive in Mexican territory together and by the same means of transportation.
This does not make restricted or regulated goods unrestricted.
Passport, visa and Mexico entry checks
Airport-code guidance cannot determine whether a traveler has the right documents to enter Mexico. Entry requirements depend on nationality, passport, visa or residence status, travel purpose and other circumstances.
- Check that your passport meets the requirements applicable to your trip.
- Confirm whether your nationality requires a Mexican visa or qualifies under another documented exemption.
- Carry evidence requested for your travel circumstances rather than relying on an airline booking alone.
- For FMA use, separately check the stricter INM FMA eligibility rules.
- Recheck official guidance before departure if your immigration status is unusual or has recently changed.
Getting from CUN Airport to Cancún and the Riviera Maya
ASUR’s current ground-transport directory lists ADO transport, taxis and car rental among the airport options. Your best choice depends on final destination, group size, luggage and whether you want a fixed pre-booked meeting arrangement.
ADO bus
ASUR currently lists ADO city transport at Terminals 2, 3 and 4.
Check ADO’s current timetable and destination before travel because departure times are operational information.
Airport taxi
ASUR lists taxi service as an airport ground-transport option. Follow the current authorized airport process and confirm the destination and fare arrangement before departure.
Rental car
Car-rental service is available at the airport. If you book in advance, confirm whether the company uses a counter, meeting point or shuttle arrangement for your terminal.
What to send a CUN shuttle or private-transfer company
Send these details
- Airport: CUN
- Operating airline
- Full flight number
- Arrival date
- Scheduled arrival time
- Current terminal
- Lead passenger name
- Hotel, resort or final destination
Avoid these incomplete messages
- “Cancún Airport” with no flight number
- “CUN” with no terminal
- Hotel name with no arrival flight
- A screenshot taken weeks earlier with no recheck
- An airline name without specifying the actual flight
CUN to Cancún, Playa del Carmen, Akumal and Tulum
Cancún International Airport is the principal air gateway for Cancún and also serves a large share of travelers continuing south through the Riviera Maya. The airport itself is not the same thing as Cancún’s Hotel Zone, Playa del Carmen or Tulum, so ground transport needs to be planned separately.
Confirm whether you are going to downtown Cancún, the Hotel Zone or another address. “Cancún” alone may be too broad for a driver.
Playa del Carmen is south of the airport. Check current bus or transfer arrangements rather than assuming a city taxi fare or travel time.
For resort areas between Playa del Carmen and Tulum, use the full resort name and address when reserving transport.
Do not assume CUN is the only airport that can appear for a Tulum trip. Check the actual airport code on the ticket before booking airport transport.
Where is Cancún International Airport?
CUN is in Quintana Roo on Mexico’s Caribbean side. ASUR’s recent corporate reporting places the airport approximately 16 km, or about 10 miles, from the city of Cancún.
Road travel time should not be inferred from distance alone. Traffic, construction, destination within Cancún and the final Riviera Maya location can materially change the journey.
Parking and private-car planning
ASUR’s current corporate reporting confirms public automobile parking at its Mexican airports, including the Cancún airport system. Parking is separate from airline terminal information, so drivers should confirm the correct terminal approach and current parking conditions before travel.
Dropping someone off
Get the terminal from the passenger’s current itinerary before entering the airport road system. A CUN booking alone does not tell you which terminal curb to use.
Picking someone up
Wait until the passenger has completed immigration, baggage and customs where applicable. A plane’s landing time is not the same as the time the traveler will reach the public arrivals area.
Parking charges
Do not rely on an old tariff screenshot. Published airport parking tariffs can change, so confirm the current amount before using a price in a travel budget.
Terminal 1 construction
Road and curb planning may evolve as Terminal 1 construction reaches completion. Follow current airport signage instead of an older map.
Food, shopping, ATMs, baggage services and lounges
ASUR’s current passenger directory shows a substantial range of services across Terminals 2, 3 and 4. Individual businesses and opening hours can change, so use this as a service-category guide rather than a promise that a specific outlet will be open when you arrive.
Restaurants and fast food
ASUR lists restaurants, cafés and food-court options across T2, T3 and T4.
Duty free and retail
Duty-free, convenience, cosmetics, boutiques, destination shops and other retail categories are listed in the official directory.
Banking and ATMs
ASUR lists bank and ATM services in the passenger-terminal complex, with locations varying by terminal.
Baggage wrapping
ASUR lists Secure Wrap services in Terminals 2, 3 and 4.
Passenger lounges
ASUR’s current lounge directory lists Mera lounge locations in T2, T3 and T4, as well as Global Lounge listings. Lounge access is controlled by the lounge or access program, not by this guide.
- Mera: Terminal 2 Gates A
- Mera: Terminal 3 near C16
- Mera: Terminal 4 around Gates 54 and 60
Tourist and communications services
ASUR lists tourist-information and telephone-related services in the active passenger terminals. Locations can be useful if you need local information after clearing arrivals.
Wheelchair and special-assistance planning
If you need wheelchair assistance, boarding support or another passenger-specific accommodation, arrange it with the operating airline before travel and reconfirm it if the itinerary changes.
- Tell the airline what assistance is needed instead of requesting only “special assistance.”
- Check that the request appears on the current booking.
- Confirm the terminal before arranging a separate caregiver, driver or pickup.
- Allow additional time if mobility makes long terminal movements difficult.
- Ask the airline who is responsible if assistance does not appear at the expected point.
Missing bag vs item lost inside the airport
Checked bag did not arrive
Start with the operating airline’s baggage service because the airline controls the checked-baggage record and tracing process.
Keep the baggage-tag receipt, boarding pass and any baggage report number.
Personal item lost in the terminal
If the item was not checked baggage and you believe it was left in the terminal, use the airport’s current information or contact route for the relevant terminal.
Describe where and approximately when you last had the item.
Connections at CUN: terminal and baggage questions to answer first
Do not plan a connection based only on the fact that both flights use CUN. A workable connection depends on whether you must change terminals, collect and recheck baggage, complete immigration/customs, or obtain a new boarding pass.
Same ticket
Ask the operating airline whether your bag is checked through and whether any terminal change is required. Airline protection and rebooking rules can differ from a self-made connection.
Separate tickets
Treat the transfer more conservatively. You may have to retrieve baggage, complete arrival requirements and check in again with another airline.
- Check both terminal numbers.
- Ask where checked bags are tagged to.
- Confirm whether immigration/customs occurs at CUN.
- Check the second airline’s check-in and baggage cutoffs.
- Do not rely on a minimum time from an unrelated itinerary.
Common CUN travel problems and what to do
| Problem | Likely issue | What to do |
|---|---|---|
| Booking site rejects MMUN | You are using the ICAO identifier in a passenger booking field. | Search with CUN. |
| Driver cannot find you | The provider has CUN but not the current terminal or flight number. | Send airline, full flight number, terminal and passenger name. |
| Old website says T1 is open | It may be using the superseded July 2026 planning date. | Use current ASUR/airline information; ASUR later moved the planned opening to Q4 2026. |
| FMA gate will not apply to you | Age, passport, travel purpose, nationality or immigration category may not qualify. | Use the staffed immigration process and follow INM instructions. |
| FMMD not downloaded | The FMA ticket QR process has not been completed. | Keep the ticket and follow INM’s current FMMD download instructions. |
| Checked bag missing | Airline baggage irregularity. | Report it to the operating airline and retain the case number. |
| Unsure whether goods need declaration | Customs rules can depend on product, quantity and value. | Check ANAM guidance or ask customs personnel. |
What to verify before a CUN trip
- Your itinerary says CUN, not a different airport code.
- The operating airline and flight number are correct.
- You have the current terminal, not an old terminal from a previous trip.
- Your passport and destination-specific travel documents are ready.
- If entering Mexico, you have checked current immigration requirements.
- If planning to use FMA, you meet INM’s current eligibility conditions.
- Your transfer provider has your terminal and flight number.
- You know whether checked baggage is through-checked on a connection.
- You have an offline copy of essential booking and pickup information.
- You have rechecked flight status before leaving for the airport.
