CountriesCurrency codes
Every currency has a three-letter code set by the standard ISO 4217. The first two letters are usually the country code and the third is the first letter of the currency: INR is the Indian rupee, JPY the Japanese yen. Banks and money changers use these codes because many currencies share a name. There are more than twenty different "dollars".
Shared currencies
16 currencies are used in more than one place. The most widely shared are the euro (37), the United States dollar (16), the Eastern Caribbean dollar (8), the West African CFA franc (8), the Australian dollar (7). Some small countries use a neighbour's money next to their own, which is why a few countries appear under two currencies.
This page lists which money is used where. It does not show exchange rates, which change every minute. Check your bank or a money changer for today's rate.
Names that many currencies share
A currency's name often tells of its history. Counting the last word of each name in the table above gives: dollar (22), franc (10), pound (9), peso (8), dinar (8), rupee (6), shilling (4), rial (3). A shared name does not mean a shared value. The Indian rupee, the Pakistani rupee and the Sri Lankan rupee are three separate currencies, and so are the many dollars.
Places with two currencies
19 entries in the data list more than one currency, for example Bahamas, Bhutan, Brunei, Cambodia, Cook Islands, Eswatini, Faroe Islands, Guernsey. In most of them a local currency circulates beside a stronger foreign one that is also accepted in shops.
Symbols
A symbol such as $ or £ is shorter than a code but less exact, since many currencies use the same sign. The rupee sign ₹ was adopted by India in 2010 and is used only for the Indian rupee. On a price list for foreign readers, the three-letter code is the safest way to write an amount: INR 500, USD 20.
