ISO 4217 is a standard published by International Organization for Standardization (ISO) that defines alpha codes and numeric codes for the representation of currencies and provides information about the relationships between individual currencies and their minor units. This data is published in three tables:
- Table A.1 – Current currency & funds code list
- Table A.2 – Current funds codes
- Table A.3 – List of codes for historic denominations of currencies & funds
The first edition of ISO 4217 was published in 1978. The tables, history and ongoing discussion are maintained by SIX Interbank Clearing on behalf of ISO and the Swiss Association for Standardization.
The ISO 4217 code list is used in banking and business globally. In many countries the ISO 4217 alpha codes for the more common currencies are so well known publicly that exchange rates published in newspapers or posted in banks use only these to delineate the currencies, instead of translated currency names or ambiguous currency symbols. ISO 4217 alpha codes are used on airline tickets and international train tickets to remove any ambiguity about the price.
In the case of national currencies, the first two letters of the alpha code are the two letters of the ISO 3166-1 alpha-2 country code and the third is usually the initial of the currency itself. So Japan's currency code is JPY—JP for Japan and Y for yen. This eliminates the problem caused by the names dollar, franc, peso and pound being used in dozens of countries, each having significantly differing values.
In some cases, the third letter of the alpha code is not the initial letter of the currency name. There are two possible reasons for this to happen:
- It is considered important that the code of a completely new currency be highly mnemonic. An example is the assignment of the code EUR to the euro. ISO 4217 amendment 94, which created this code, states “The code element 'EU' has been reserved by the ISO 3166 Maintenance Agency for use within ISO 4217 where 'R' has been appended to make an acceptable mnemonic code.”. Here the R comes from the third letter in the word “euro”.
- The currency in question is replacing another currency of the same name, due to devaluation. So that the two currencies have different codes, a different third letter must be chosen for the code of the new currency. In some cases, the third letter is the initial for "new" in that country's language, to distinguish it from an older currency that was revalued; the code sometimes outlasts the usage of the term "new" itself (for example, the code for the Mexican peso is MXN). Another solution to a devalued currency having the same name as its predecessor is to choose a third letter which results in a 3-letter code with mnemonic significance. For example, the Russian ruble changed from RUR to RUB following a devaluation, where the B comes from the third letter in the word "ruble".
In addition to codes for most active national currencies ISO 4217 provides codes for "supranational" currencies, procedural purposes, and several things which are "similar to" currencies:
- Codes for the precious metals gold (XAU), silver (XAG), palladium (XPD), and platinum (XPT) are formed by prefixing the element's chemical symbol with the letter "X". These "currency units" are denominated as one troy ounce of the specified metal as opposed to "USD 1" or "EUR 1".
- The code XTS is reserved for use in testing.
- The code XXX is used to denote a "transaction" involving no currency.
- There are also codes specifying certain monetary instruments used in international finance, e.g. XDR is the symbol for special drawing right issued by the International Monetary Fund.
- The codes for most supranational currencies, such as the East Caribbean dollar, the CFP franc, the CFA franc BEAC and the CFA franc BCEAO. The predecessor to the euro, the European Currency Unit (ECU), had the code XEU.
The use of an initial letter "X" for these purposes is facilitated by the ISO 3166 rule that no official country code beginning with X will ever be assigned.
The inclusion of EU (denoting the European Union) in the ISO 3166-1 reserved codes list allows the euro to be coded as EUR rather than assigned a code beginning with X, even though it is a supranational currency.
ISO 4217 also assigns a three-digit numeric code to each currency, much like the three-digit numeric code assigned to each country by ISO 3166. The numeric code assigned to a currency by ISO 4217 is usually the same as the numeric code assigned to the corresponding country by ISO 3166-1. For example, USD (United States dollar) has numeric code 840 which is also the numeric code for the US (United States).
Minor units of currency
The 2008 (7th) edition of ISO 4217 says the following about minor units of currency:
Requirements sometimes arise for values to be expressed in terms of minor units of currency. When this occurs, it is necessary to know the decimal relationship that exists between the currency concerned and its minor unit. This information has therefore been included in this International Standard and is shown in the column headed “Minor unit” in Tables A.1 and A.2; “0” means that there is no minor unit for that currency, whereas “1”, “2” and “3” signify a ratio of 10:1, 100:1 and 1 000:1 respectively. The names of the minor units are not given.
Examples for the ratios of 100:1 and 1 000:1 include the United States dollar and the Bahraini dinar, for which the column headed “Minor unit” shows “2” and “3”, respectively. As of 2021[update], two currencies have non-decimal ratios, the Mauritanian ouguiya and the Malagasy ariary; in both cases the ratio is 5:1. For these, the “Minor unit” column shows the number “2”. Some currencies do not have any minor currency unit at all. These show the number “0”, as with currencies whose minor units are unused due to negligible value.
Position of ISO 4217 code in amounts 
The ISO standard does not regulate either the spacing, prefixing or suffixing in usage of currency codes. According however to the European Union's Publication Office, in English, Irish, Latvian and Maltese texts, the ISO 4217 code is to be followed by a hard space and the amount:
- a sum of EUR 30
In Bulgarian, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Lithuanian, Polish, Portuguese, Romanian, Slovak, Slovene, Spanish and Swedish the order is reversed; the amount is followed by a hard space and the ISO 4217 code:
- une somme de 30 EUR
Note that, as illustrated, the order is determined not by the currency, but by the native language of the document context.
In 1973, the ISO Technical Committee 68 decided to develop codes for the representation of currencies and funds for use in any application of trade, commerce or banking. At the 17th session (February 1978), the related UN/ECE Group of Experts agreed that the three-letter alphabetic codes for International Standard ISO 4217, "Codes for the representation of currencies and funds", would be suitable for use in international trade.
Over time, new currencies are created and old currencies are discontinued. Such changes usually originate from the formation of new countries, treaties between countries on shared currencies or monetary unions, or redenomination from an existing currency due to excessive inflation. As a result, the list of codes must be updated from time to time. The ISO 4217 maintenance agency (MA), SIX Interbank Clearing, is responsible for maintaining the list of codes.
The following is a list of active codes of official ISO 4217 currency names as of 29 August 2018[update]. In the standard the values are called "alphabetic code", "numeric code", "minor unit", and "entity".
USD/USN, two currency codes belonging to the US
The US dollar has two codes assigned: USD and USN (next day). The USS (same day) code is not in use any longer, and was removed from the list of active ISO 4217 codes in March 2014.
According to UN/CEFACT recommendation 9, paragraphs 8–9 ECE/TRADE/203, 1996, available online:
- 8. In applications where monetary resources associated with a currency (i.e. funds) need not be specified and where a field identifier indicating currency is used, the first two (leftmost) characters are sufficient to identify a currency—example: US for United States dollars for general, unspecified purposes where a field identifier indicating currency is present. (A field identifier can be a preprinted field heading in an aligned document or a similarly-agreed application in electronic transmission of data.)
- 9. In applications where there is a need to distinguish between types of currencies, or where funds are required as in the banking environment, or where there is no field identifier, the third (rightmost) character of the alphabetic code is an indicator, preferably mnemonic, derived from the name of the major currency unit or fund—example: USD for general, unspecified purposes; USN for United States dollar next-day funds, and USS for funds which are immediately available for Federal Reserve transfer, withdrawal in cash or transfer in like funds (same-day funds). Since there is no need for such a distinction in international trade applications, the funds codes have not been included in the Annex to the present Recommendation.
As of August 2018, there are no new codes planned to be added to the standard.
Non ISO 4217 currencies
Currencies without ISO 4217 currency codes
A number of active currencies do not have an ISO 4217 code, because they may be: (1) a minor currency pegged at par (1:1) to a larger currency, even if independently regulated, (2) a currency only used for commemorative banknotes or coins, or (3) a currency of an unrecognized or partially recognized state. These currencies include:
- Abkhazian apsar
- Alderney pound (1:1 pegged to the pound sterling)
- Artsakh dram
- Cook Islands dollar (1:1 pegged to the New Zealand dollar)
- Faroese króna (1:1 pegged to the Danish krone)
- Guernsey pound (1:1 pegged to the pound sterling)
- Isle of Man pound (1:1 pegged to the pound sterling)
- Jersey pound (1:1 pegged to the pound sterling)
- Kiribati dollar (1:1 pegged to the Australian dollar)
- Maltese scudo (1:0.24 pegged to the euro)
- Sahrawi peseta (pegged to the euro), sometimes given the code "EHP" but this has not been assigned by the ISO
- Somaliland shilling (state of issue is viewed as de jure part of Somalia, exchange rate not fixed)
- Transnistrian ruble (state of issue is viewed as de jure part of Moldova)
- Tuvaluan dollar (1:1 pegged to the Australian dollar)
- Zimbabwean bonds
- RTGS dollar (ZWL occasionally used)
See Category:Fixed exchange rate for a list of all currently pegged currencies.

Unofficial codes for minor units of currency
Minor units of currency (also known as currency subdivisions or currency subunits) are often used for pricing and trading stocks and other assets, such as energy, but are not assigned codes by ISO 4217. Two conventions for representing minor units are in widespread use:
- Replacing the third letter of the ISO 4217 Code of the parent currency with an upper-case "X". Examples are GBX for Penny Sterling, USX for the US Cent, EUX for the Euro Cent.
- Replacing the third letter of the ISO 4217 Code of the parent currency with the first letter of the name of the minor unit, using lower-case. Examples are GBp for Penny Sterling, USc for the US Cent, EUc for the Euro Cent.
A third convention is similar to the second one but uses an upper-case letter, e.g. ZAC for the South African Cent. This convention is not in widespread use as it would result in clashes, e.g. between GBP for Pound Sterling and GBP for Penny Sterling.
Unofficial codes for cryptocurrencies
Recently, cryptocurrencies have unofficially used ISO-like codes on various cryptocurrency exchanges, for instance LTC for Litecoin, NMC for Namecoin and XRP for the XRP Ledger. SIX Interbank Clearing (a Maintenance Agency of ISO) is currently studying the effect and role of cryptocurrencies and other independent currencies on ISO 4217.
|ADA||6||Ada||Currency on the Cardano platform conflicts with ISO 4217, because AD stands for Andorra.|
|BNB||8||Binance||BNB conflicts with ISO 4217, because BN stands for Brunei Darussalam.|
|BSV||8||Bitcoin SV||BSV (Bitcoin Satoshi Vision) conflicts with ISO 4217, because BS stands for Bahamas.|
|BTC, XBT||8||Bitcoin||BTC conflicts with ISO 4217, because BT stands for Bhutan.|
|DASH||8||Dash||DASH is of non-standard length.|
|ETH||18||Ethereum||ETH conflicts with ISO 4217, because ET stands for Ethiopia.|
|LTC||8||Litecoin||LTC conflicts with ISO 4217, because LT stands for Lithuania.|
