Mexico Electronic Pre-Registration System
Complete your Mexico Electronic Pre-Registration System (SAE) application online before flying — official air pre‑authorization with PDF/email confirmation.
What Is the Mexico Electronic Pre-Registration System?
The Mexico Electronic Pre-Registration System (often shown on government pages as SAE or "Sistema de Autorización Electrónica") is an official online pre‑authorization for eligible air passengers entering Mexico. Reinstated and updated in 2026 for selected nationalities, the system was introduced to streamline immigration checks for travellers arriving by air and to replace paper-only pre‑screening procedures in many consular workflows. The National Institute of Migration (Instituto Nacional de Migración — INM) administers electronic pre‑authorizations and publishes instructions on its official portal.
Applicants complete the online questionnaire on the INM/SAE portal or the consular e‑authorization website, upload any required identity pages, and submit their details before travel. Upon approval you receive a printable authorization and an electronic confirmation (PDF or email) to present at airline check‑in and on arrival. Many airlines ask to see the approval at departure so keep the printed copy or the PDF on your mobile device.
The Mexico Electronic Pre-Registration System is an entry pre‑authorization — it is not a visa in itself for travellers who remain subject to standard visa rules. The authorization confirms that immigration has pre‑reviewed your trip; final admission is decided by the immigration officer at the port of entry. Recent 2026 updates expanded SAE eligibility for specific nationalities arriving by air and clarified the requirement to hold an electronic passport for applicants in some categories.
For full background and to check whether you need this authorization, review Mexico visa information and the official INM portal at https://visaelectronica.sre.gob.mx/ingresar or the INM pre‑authorization pages. Apply now to start your guided application and get help preparing the printable confirmation before you travel.

Mexico Entry Requirements & Restrictions
Passport Validity
You must travel on a valid passport. Certain consular guidance advises a passport validity of more than 6 months for visitors in some categories — check your consulate or the INM pre‑authorization portal for details. See the consulate checklist at Consulmex guidance.
Vaccination & Health Advice
No routine vaccinations are mandatory for entry, but public health authorities advise being up to date on routine vaccines (MMR, tetanus, influenza). Review CDC Mexico health information for recommendations before travel: CDC — Mexico.
Customs Restrictions & Prohibited Imports
Mexico restricts or prohibits certain imports — notably narcotics and items subject to sanitary control. Recent customs law reforms changed import rules in 2025–2026; check official guidance for agricultural products, used clothing, medicines, and other regulated goods at U.S. ITA — Mexico customs reform.
Vehicle & Special Permits
If you plan to enter Mexico with a foreign vehicle, an electronic pre‑authorization for temporary import or a printed permit may be required — complete the INM vehicle pre‑authorization and bring the printed form to the border. See INM pre‑authorization instructions at INM — Electronic pre‑authorization.
Travel Insurance
Travel insurance is not mandatory at the border but is strongly recommended — medical care and evacuations can be costly and services outside major cities are limited.
Travel Tips for Mexico Visitors
Mexico is a geographically large country with diverse regions — plan transfers and documents carefully. Major international airports receive most international flights and are staffed to process electronic authorizations at arrival and airline check‑in.
- Currency: Mexican Peso (MXN). US dollars (USD) are widely accepted in tourist areas and major resorts, but carry pesos for smaller purchases and local markets.
- Language: Spanish is the official language; English is commonly spoken in hotels, airports and tourist centres.
- Time zone: Mexico spans multiple zones; Mexico City operates on Central Time (approx. GMT‑6) — confirm local time before travel.
- Airports: International entry points include Mexico City International Airport (Benito Juárez), Cancún International Airport, Guadalajara (Miguel Hidalgo y Costilla), Monterrey (General Mariano Escobedo), Tijuana, Los Cabos (San José del Cabo), Puerto Vallarta, Mérida and Cozumel — present your printed authorization at airline check‑in and immigration.
- Print your approval: Some consular guidance specifically requires a printed copy of the electronic authorization for presentation at check‑in and arrival — bring a PDF and a screenshot.
- Check airline rules: Airlines commonly verify electronic authorizations at departure — failure to show the approval may delay boarding.
- Protect documents: Keep passport, printed SAE confirmation, and return/onward ticket together; immigration officers may ask for accommodation and proof of funds.
- Local laws & customs: Be aware of regional safety advice from your government travel advisory and avoid restricted areas; register travel plans with your embassy for longer stays.
