ISO 4217 is the international standard established by the International Organization for Standardization (ISO) that defines three-letter codes for currencies. It was first published in 1978 and is widely used in banking, finance, foreign exchange trading, and international commerce. Each code consists of three letters — for example, USD for United States Dollar, EUR for Euro, and GBP for British Pound Sterling. The standard also includes numeric codes and minor unit information.

Simply type or paste the 3-letter ISO 4217 currency code into the search box above. Our tool instantly looks up the corresponding currency symbol — for example, entering "USD" returns $, "EUR" returns €, and "GBP" returns £. You can also search by currency name or country. For batch queries, switch to Batch mode and paste multiple codes at once.

Many currencies use the dollar sign ($) or peso sign because their names derive from the Spanish dollar (piece of eight). Over 30 currencies worldwide use the $ symbol, including the US Dollar (USD), Canadian Dollar (CAD), Australian Dollar (AUD), Mexican Peso (MXN), and many others. Similarly, several Scandinavian countries use kr for their respective kroner. When precision is needed, context or the ISO code should be used to disambiguate.

A currency code (like USD, EUR, JPY) is a standardized 3-letter identifier defined by ISO 4217 — it is unambiguous and used in formal financial contexts, SWIFT transfers, and data systems. A currency symbol (like $, €, ¥) is a typographic glyph used in everyday pricing and displays. Symbols can be ambiguous ($ is used by dozens of currencies), while codes are always unique. Our tool bridges the gap between the two.

No. Cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), and others are not part of the official ISO 4217 standard. However, due to popular demand, our tool includes several major cryptocurrencies as non-ISO entries for reference. Unofficial codes like BTC (₿), ETH (Ξ), and USDT (₮) are widely recognized in the crypto community. For formal ISO compliance, only fiat currencies issued by sovereign nations are included.

ISO 4217 currently defines approximately 160-170 active currency codes for circulating currencies worldwide. This includes major currencies, minor currencies, and currencies of dependent territories. Additionally, there are historical codes for currencies that have been replaced or withdrawn (such as the German Mark - DEM, or French Franc - FRF). Our tool covers all active codes plus the most commonly referenced historical ones.

Many smaller or less-traded currencies lack a widely recognized single-character symbol. In such cases, the currency is typically represented by its ISO code or an abbreviation. Examples include the Uzbekistani Som (UZS), Tanzanian Shilling (TZS), or CFA Franc (XOF/XAF). Our tool displays the most commonly used representation — whether it's a dedicated symbol, an abbreviation, or the code itself.

Yes! This tool is ideal for developers building financial software, e-commerce platforms, or internationalization features. Use the batch query mode to process multiple codes at once, and copy symbols directly. For programmatic use, consider implementing a lookup table based on the ISO 4217 standard in your codebase. Our data is carefully curated to match the official ISO standard with accurate Unicode symbol representations.

In ISO 4217, codes beginning with "X" are reserved for special purposes. For example, XAU represents gold (troy ounce), XAG for silver, XDR for Special Drawing Rights (IMF), and XBT is sometimes used for Bitcoin. Codes starting with X are generally not assigned to any specific country and are used for supranational currencies, commodities, or testing purposes.
