Mexico

Uber and DiDi are useful optional tools in many cities, but coverage, vehicle supply and airport pickup arrangements vary by airport, state and resort. Mexico's federal transport authority states that ride-app companies do not hold federal authorization to carry passengers in airport zones, even though app marketing and day-to-day pickup practice can suggest otherwise. Follow current airport signs and staff, and use an authorized taxi, bus or prebooked licensed transfer when app pickup is not permitted. Keep every app ride active, match the vehicle and never accept a request to cancel or move payment off-platform.

Cards are common in urban and established tourism businesses, but pesos remain important for markets, tolls, small shops, local transport and payment failures. Mercado Pago and Spin by OXXO are resident-oriented accounts, not arrival essentials. Immigration requirements vary by nationality and route. The electronic FMM page is specifically relevant to eligible land entries, while air and other arrivals may use a different paper, stamp or digital record.

Use Instituto Nacional de Migración, the relevant consulate and the carrier, and save every entry record offline. Foreign visitors to Quintana Roo must also check the official state VISITAX requirement. Security conditions differ substantially by state and road, so read current destination-specific official advice before intercity or night travel. Call 911 for an emergency.

Road travelers can call Ángeles Verdes on 078 for tourist guidance and mechanical help; its app is optional and must not be the only fallback.
