Why does a bank statement say USD instead of a dollar sign? Banks, payment apps, and accounting software use three-letter currency codes, because many currencies share the same symbol. A code removes any doubt about which money is meant.
The Currency Code Finder looks up ISO 4217 currency codes for major world currencies. Search by code, name, symbol, or country to see the numeric code, decimal places, and where each currency is used. It helps bookkeepers, online sellers, developers, and travelers check a code before they use it.

What the Tool Does
The finder searches a built-in list of 35 major currencies from the ISO 4217 standard. It ranges from the US dollar and euro to the Thai baht, Nigerian naira, and Kuwaiti dinar.
- Live search: results update as you type, with no button to press.
- Matched Currencies card: how many records match, shown as 1 Match or 7 Matches.
- ISO Code and Symbol cards: the code and symbol of the first match.
- Reference table: code, name, symbol, numeric code, minor decimals, and primary countries for every match.
- Copy Specifications button: copies the table as plain text and briefly confirms the copy.
How to Use It, Step by Step
- Find the box labeled Search Currency Code, Numeric Code, Name, Symbol, or Country. It starts with USD.
- Type a code like GBP, a number like 840, a name, or a country like Japan.
- Or type a symbol, such as €, ¥, or $. A $ search also finds prefixed signs like CA$.
- Check the top cards for the first match.
- Read the ISO 4217 Currency Reference Specification table for all matches.
- Press Copy Specifications to copy the table.
How the Search Works
The tool ignores capital letters and trims extra spaces. It then checks five fields, and each field only needs to contain your text.
Search Text→Code, Numeric, Name, Symbol, or Country Contains It→Best Hit Sorted First→Matches Table
Results sort with exact codes first, then exact numeric codes, exact symbols, and built-in order. So a $ search shows USD first, followed by CA$, A$, and six more.
Example Searches
Marcus runs a small export business and checks codes for his invoices. These are the results he gets.
| Search | Matches | First Match |
|---|
| USD | 1 | USD, $ |
| dollar | 7 | USD, then CAD, AUD, and four more |
| Japan | 1 | JPY, ¥ |
| Ecuador | 1 | USD, $ |
| us | 3 | USD, then AUD and RUB |
| 840 | 1 | USD, $ |
| Kuwait | 1 | KWD, KD |
The search for us also finds AUD and RUB, because Australia and Russia contain those letters. The 840 search works through the numeric code column.
How to Read the Results
- Code: the three-letter ISO 4217 code, such as GBP.
- Currency Name: the full name, such as British Pound Sterling.
- Symbol: the sign shown before amounts. Some use a prefix, like CA$ and A$, to tell dollars apart.
- Numeric: the three-digit ISO code, such as 840 for USD and 036 for AUD.
- Minor Decimals: how many decimal places the currency uses. Most show 2, and KWD shows 3.
- Primary Countries: places that use the currency, such as Ecuador and El Salvador for USD.
Understanding ISO 4217 Codes
ISO 4217 is the international standard for currency codes. The first two letters usually match the country code, and the third often starts the currency name. USD means United States dollar, and JPY means Japan yen.
The numeric code often matches the country's numeric code too, like 392 for Japan. The euro is an exception, since it is shared by many countries and uses 978. The Kuwaiti dinar splits into 1,000 smaller units, so it uses 3 decimals.
For the matching symbols and web codes, try our currency symbol lookup tool. It adds HTML entities and Unicode values.
Where Currency Codes Matter
Invoices to foreign clients should show the code beside the total, such as 2,400.00 CAD. The invoice total calculator works out a total with discount, sales tax, and shipping.
The code finder does not show exchange rates. Use the currency converter when you need to change an amount between currencies. Forex traders see pairs like EUR/USD, and the pip calculator estimates the value of small price moves.
Travelers can price a trip in dollars with the travel budget calculator. See more tools in the finance and business hub.
Limitations and Assumptions
- The list holds 35 major currencies, not the full ISO 4217 list. Rare and regional codes may be missing.
- Short searches can match by accident, like us matching Australia.
- Country lists are partial. For example, the euro row lists only a few Eurozone members.
- Only the first match fills the top cards. Check the table when several currencies match.
- The data is fixed text inside the tool. New or changed codes need a tool update.
FAQs About the Currency Code Finder
What is an ISO 4217 currency code?
It is a standard three-letter code for a currency, such as USD or EUR. Each currency also has a three-digit numeric code.
How do I find the code for a country's currency?
Type the country name, such as Japan, into the search box. The ISO Code card shows the result if that currency is in the list.
Why do some currencies have 0 decimal places?
The yen, won, and dong have no smaller unit in everyday use. ISO 4217 lists 0 minor decimals for JPY, KRW, and VND, so prices are whole numbers.
Why does a search for 36 return two currencies?
Numeric codes always have three digits, so Australia's code is 036 and Indonesia's is 360. Both contain 36, so type all three digits for one exact result.
Which countries use the US dollar?
Besides the United States, the tool lists Ecuador and El Salvador. Both use the US dollar as official currency.
Is Bitcoin in the code finder?
No. BTC is a common market label, not an ISO 4217 code, so this tool leaves it out. The currency symbol lookup tool lists Bitcoin with a not ISO label.
