About currency codes
ISO 4217 currency codes are the three-letter tags — USD, EUR, JPY — that keep money unambiguous across borders, banks, and payment systems. This directory lists every currency used by published countries, its symbol, and where it is accepted.
Frequently asked questions
What is an ISO 4217 currency code?
An ISO 4217 code is a three-letter identifier that names a currency unambiguously. The first two letters usually come from the country code (US for United States → USD) and the third from the currency name (D for dollar). This standard is used by banks, payment networks, and accounting systems worldwide.
Why does not every currency have a symbol?
Symbols like $ and € are informal shorthand, not part of the ISO standard, and many currencies never adopted a widely recognized symbol. The three-letter code is always the safe, unambiguous way to write an amount when a currency could be confused with another.
Why does the euro have one code for many countries?
The euro is a shared currency, so every country that uses it shares the single ISO code EUR. This directory shows EUR once and lists the countries that use it, rather than duplicating the code for each country.
What happens when a country replaces its currency?
When a currency is replaced, the old code is eventually withdrawn from ISO 4217 and the new code takes over. Historical codes can be reused after a waiting period, which is why checking the current code matters for accurate records.
Why are exchange rates not shown here?
Exchange rates change by the second and are outside the scope of a stable reference. This directory gives you the durable facts — code, name, symbol, and the countries that use it — and leaves live rates to dedicated currency converters.
