What is the ISO 4217 code for the Mexican peso? MXN.
MXN is the three-letter ISO 4217 code assigned to Mexico’s current peso. In the code, “MX” identifies Mexico, while the final “N” distinguishes the modern currency from the earlier peso used before a major 1993 revaluation. The Mexican peso is also commonly written with the dollar sign, so financial institutions may use “Mex$” when extra clarity is needed.
The earlier code was MXP. That distinction matters because old prices, historical exchange tables, and financial records may use MXP rather than the current MXN. The peso is divided into 100 centavos, and the Bank of Mexico is the issuing authority.
PEN is the Peruvian sol, not the Mexican peso. “MEX” is not the ISO 4217 currency code, even though it resembles a country abbreviation. The peso itself has deep Spanish-colonial roots and shares the dollar sign’s historical connection to the Spanish dollar, which circulated widely in international trade.
