It is possible to exchange U.S. dollars for pesos at banks and currency exchange offices. Some banks require customers to have an account with them, and not all banks provide exchange services. Customers can also use ATM machines to remove money from bank accounts and have it dispensed in pesos.
ATMs offer the most convenient method of receiving pesos and usually have the best exchange rates. A service fee is often charged if the customer does not have an account with the affiliated bank of the specific ATM machine. Currency exchange offices are in international airports throughout Mexico. Customers must provide a passport at these offices in order to exchange money. Mexican merchants are no longer allowed to exchange U.S. dollars for pesos, but most can provide information about where to exchange currency.
