Frequently Asked Questions

How are the three letters of an ISO 4217 code determined?

Usually country code (2 letters) + currency initial: CN (China) + Y (Yuan) = CNY; in USD, US is the country and D stands for Dollar. Some are historical exceptions (e.g. GBP). The numeric code (e.g. 156 for CNY) is unrelated to the letters.

Both CNY and JPY use ¥ — how to tell them apart?

Yes, they share ¥. Disambiguate in writing by the ISO code: CNY (Chinese Yuan) vs JPY (Japanese Yen). In UI, show the code or a localized symbol (e.g. RMB for CNY, JP¥ for JPY) to avoid confusion.

Why do some currencies have no decimals (JPY, KRW)?

The smallest unit differs: JPY and KRW are counted in whole yen/won with no subunit, so 0 decimal places; CNY and USD have jiao/fen, so 2 decimals. ISO 4217 records this in the minor-unit field.

Does Bitcoin (BTC) have an ISO 4217 code?

No official ISO 4217 code. ISO reserves XBT as a non-official/experimental code (X prefix = non-country), but most exchanges still use BTC. Commodities like gold are also outside ISO 4217.
