The Mexican peso (MXN) is the national currency; US dollars are by far the most exchanged, followed by Canadian dollars and euros, and Guatemalan quetzales and Belize dollars appear near the southern border. Mexico City has the most offers, followed by Guadalajara, Monterrey, Cancún and Tijuana.
Exchange houses (casas de cambio) operate in airports, shopping centres and tourist areas, and remittances from the United States are a major source of dollars. P2P offers let you swap USDT or USDC for pesos in cash or by SPEI transfer.
