Here is a list of Contact Info for eAPIS and AIU for many Mexico Airports. I maintain this for eAPISfile.com. Please feel free to provide any updates so i can keep it current. The Database includes all the USA Customs ports, and their contact information as well as their Fact Sheets. Use the Filter at the Top Right of the page to filter the displayed airports (The bottom 2 are the Mexico Airport Contacts.) NOTE: eAPISFile uses this DB to send the AIU and Mexico eAPIS for you. However, you can use this report as a reference guide.

On May 20, 2025, the Diario Oficial de la Federación (DOF) published an amendment to Article 7 of the General Guidelines for the Transmission of Electronic Passenger, Crew, and Transport Lists to the Instituto Nacional de Migración (INM). This reform will go into effect on September 17, 2025 and applies to all private and charter operators flying into or out of Mexico.

Article 250 of the Migration Law establishes that failing to comply may result in fines ranging from $1,471.00 USD to $14,711.00 USD, showing the importance of these transmissions.

The General Guidelines were first issued on November 8, 2012, and since then the requirements have evolved several times with changes to timelines and procedures.

As of September 17, the amendment establishes a mandatory two-step transmission process:

First submission: within two hours before departure, whether the flight is inbound to Mexico or outbound to another country.

Second submission: a confirmation of passengers on board, sent once the aircraft doors have closed and before takeoff.

To comply, operators must use one of the official channels established by INM: (ARINC)

Operators without ARINC access: Email the Excel spreadsheet directly to INM: apisinm@inami.gob.mx

The reform, was published in the DOF on May 20, 2025, and becomes mandatory on September 17, 2025. The complete text can be found here: DOF Publication – May 20, 2025.

This amendment brings a clear tightening of APIS requirements in Mexico. As these rules keep changing, operators should stay alert and expect more adjustments in the future. The safest way to avoid issues is to review procedures before every flight and make sure the team is ready to comply with the latest requirements.

Editors Note: What I think they are really doing is Standardizing the process the same as Commercial Part 135 current has to do in the USA and in Mexico.
A part 135 operator has to file its eAPIS Hrs prior to Departure and then Again when the "doors close" Noting any changes from the original filing. Why? It give Time to processing the eAPIS for 400 people and then “Finalizes” the Eapis with what actually happened vs what was planned. (Last minute changes, cancellations and adds)

With a single 2-page notice to all of its Comandantes, Mexico’s Civil Aviation Authority (AFAC) shut down the country’s airport system affecting hotels, Mexican air charter operators and disrupting travel plans for visiting US and Canadian pilots.

The Stats: There are 77 airports listed in Mexico’s Aeronautical Information Publication (AIP) and another 1,519 airports for fixed wing aircraft listed on the AFAC’s official airport database for a total of 1,596 total airports.

How airports are classified: Of the 1,519 airports that appear on the official AFAC list or airports, 1,504 are classified as “Service for Private Use” and 15 are classified as “Service for Private Use and 3’rd parties”. It is assumed that the 77 in the AIP are all for General Use (Cancun, Toluca, Puerto Vallarta, etc)

AFAC Ruling: Mexico’s AFAC has issued a ruling (Oficio 4.1.443) that airports classified as “Service for Private Use” can ONLY be used by the airport owner and the only aircraft that can operate there are the airport owner’s aircraft. They have instructed all comandantes to deny flight plans to any of these airports or face severe disciplinary action.

The impact: This prevents any Mexican or foreign registered aircraft to fly to many popular destinations which will have a significant negative affect on hotels that have airstrips (Hacienda de los Santos, Holbox, Punta Pescadero, etc.) and will also have a huge negative effect on Mexican air taxi operators who fly to many of those airstrips. It will also prevent any type of flight to rural communities that might depend on their airstrips for medical and other assistance such as "Doctors Without Borders".

What next: Many airport owners are just now learning about the ruling and are trying to develop a plan of action. While we are not a Mexican law firm, a review of Mexico’s Law and Regulation of Airports does not appear to support this conclusion by the AFAC but that is a matter for the Mexican airport owners and the Mexican courts to figure out to force the AFAC to reverse course. In the meantime, be patient and consider one of the main airports for your stay in Mexico or choose another destination country.

For experimental aircraft that need to enter the country, the user must submit a written request to the AFAC in Mexico City via the email ventanillaunica@afac.gob.mx. You must attach the aircraft documents, pilot's license, insurance, and in the request, state the reason for needing to be in Mexico, as well as the area in which they will be located. The authorization takes about a week to be issued.

The renewal process of Mexico Airports is a slow process. Due to the number of airports requesting the upgrated status, it is dificult to determin the status. We recommend calling the AOE airport close to your desired airport.
For Example :
The Alamos Airport (ALA), the Private and Third-Party Service permit is still being processed and all is okay with the application. Aircraft arriving from abroad can enter through any airport, for example, CEN, and the AOE will authorize the flight plan to ALA. There is no problem, or you can verify this with the Honorary Commander of ALA, Josue Noe Aragon Rabago, at +52 647 487 7504.
