Currency Codes (ISO 4217)

About Currency Codes (ISO 4217)

The Currency Codes reference lists every active world currency by its ISO 4217 code — the three-letter identifier (USD, EUR, JPY) used in payments, banking APIs, invoices and exchange-rate feeds. Each row shows the code in large copyable monospace, the currency symbol, its English name, the ISO 4217 numeric code and the number of decimal digits the currency uses.

Every currency also lists the countries that use it, shown as flag emojis with a count, so you can see at a glance that the euro spans many countries while the yen belongs to one. Search matches codes, names and symbols alike — GBP, yen and ¥ all work — and each row has a stable anchor so you can deep-link straight to a currency.

The decimal-digits column matters more than it looks: most currencies use two minor units, but the Japanese yen uses zero and a few use three. Payment APIs that take amounts in minor units will silently miscalculate if you assume two everywhere, and this table gives you the correct exponent per currency.

How to use Currency Codes (ISO 4217)

1. Type a currency code, name or symbol into the search box — for example USD, Euro or ¥.
2. Read the row for the ISO code, symbol, numeric code, decimal digits and the countries that use the currency.
3. Click the copy button to grab the three-letter code for your API call or spreadsheet.
4. Use the row anchor (for example #USD) to bookmark or share a direct link to that currency.
