What is the ISO 4217 code for the US dollar?

The ISO 4217 code for the United States dollar is USD.

ISO 4217 is the international standard for identifying currencies and certain monetary units with three-letter codes. In USD, “US” identifies the United States and “D” represents dollar. The code is used by banks, payment networks, currency exchanges, accounting systems, financial markets, and international businesses to remove ambiguity from monetary amounts.

The dollar also has the numeric ISO 4217 code 840, and its standard minor unit is the cent, with two decimal places. Thus, a price recorded as USD 25.00 identifies both the currency and the amount clearly, even in a country where another kind of dollar is used.

A common mistake is choosing a country’s internet or telephone abbreviation instead of its currency code. JPY is the Japanese yen, GBP is the pound sterling, and EUR is the euro. ISO codes are also distinct from currency symbols: the dollar sign ($) can represent several dollar currencies, whereas USD identifies one specific currency.
