Mexico FMM-E, the free form, and how to spot the sites pretending to be it.

The Forma Migratoria Múltiple Electrónica (FMM-E) is Mexico’s digital entry permit. It is required for most foreign visitors entering Mexico and is free to file on the official INM site.

Since 2023, most air travelers arriving at major Mexican airports receive a passport stamp instead of a separate FMM card. The electronic FMM is still used for land border crossings, some sea entries, and certain airports that have not fully transitioned.

The fast facts

• Official URL: inm.gob.mx/fmme/ — nothing else ends in .gob.mx, and that suffix is restricted to Mexican government entities.
• Cost: free if filed online before travel, or built into the DNI (Derecho de No Inmigrante) fee if you pay on arrival. Both routes are legal. Neither requires a third-party middleman.
• When to file: any time before you arrive. Most travelers fill it within a week of departure.
• What you need: passport, flight or crossing details, Mexico address, about 10 minutes.
• What you get: a PDF with a reference number. Print it, or have it on your phone. Keep the stub you receive at the border until you exit Mexico.
