Country Codes at a Glance

What a country code is: An ISO 3166-1 country code is a short standardised identifier for a country or territory. The standard defines three forms: a two-letter alpha-2 code (DE), a three-letter alpha-3 code (DEU) and a three-digit numeric code (276).
How many exist: ISO 3166-1 covers 249 countries, territories and special areas of geographical interest. All 249 are listed in the searchable table on this page with their currency, symbol and ccTLD.
Where you will meet them: The first two characters of every IBAN are an alpha-2 country code. So are characters 5 and 6 of every SWIFT/BIC code, the suffix of every ccTLD, and the prefix of every EU VAT number.
What they are not: A country code is not a telephone dialling code. +49 for Germany comes from ITU-T E.164, an unrelated telecoms standard. It is also not a currency code — those are three letters and come from ISO 4217.
Who maintains the standard: The ISO 3166 Maintenance Agency, part of the International Organization for Standardization. It publishes a newsletter whenever a code is added, retired or reassigned.
Uppercase or lowercase: Official ISO codes are always uppercase (DE, GB, US). Lowercase forms are used only for internet domain suffixes, so .de is the ccTLD while DE is the country code.

What is ISO 3166-1? The International Country Code Standard

ISO 3166-1 is an international standard published by the International Organization for Standardization (ISO) that defines short codes for the names of countries, dependent territories, and special areas of geographical interest. It is part of the broader ISO 3166 standard family and was first published in 1974. The standard is maintained by the ISO 3166 Maintenance Agency (ISO 3166/MA), which updates it as countries are created, dissolved, renamed, or change their political status.

ISO 3166-1 codes are the most universally adopted country identification system in the world, used across international trade, banking, travel, telecommunications, internet infrastructure, and government databases. They underpin many other global standards — for example, the first two characters of every IBAN are an ISO 3166-1 Alpha-2 code, and the country code in every SWIFT/BIC code is also drawn from this standard.

🔤 Alpha-2 Code

A two-letter code (A–Z only) uniquely identifying each country or territory. Examples: US = United States, DE = Germany, JP = Japan, AE = UAE. Alpha-2 codes are the most widely used format — found on passports, vehicle plates, internet domains, IBAN prefixes, and SWIFT codes.

🔢 Numeric Code

A three-digit numeric code assigned to each country. Numeric codes are useful in systems where the Latin alphabet cannot be used reliably — such as legacy databases, telecommunications systems, and multilingual environments. Example: 840 = United States, 276 = Germany, 826 = United Kingdom.

🌐 ccTLD

A country-code top-level domain (ccTLD) is the internet domain suffix assigned to each country for use in website addresses. ccTLDs are managed by IANA (Internet Assigned Numbers Authority) and are almost always identical to the Alpha-2 code — for example .de for Germany, .jp for Japan, .uk for the United Kingdom.

Where ISO 3166-1 Country Codes Are Used

ISO 3166-1 codes are embedded in an enormous range of international systems. Understanding where they appear helps explain why this standard matters for anyone working in finance, technology, travel, or international trade:

IBAN & International Banking

The first two characters of every IBAN (International Bank Account Number) are the ISO 3166-1 Alpha-2 code of the country where the account is held. For example, a German IBAN always starts with DE, a UK IBAN with GB, and a French IBAN with FR.

SWIFT / BIC Codes

Characters 5 and 6 of every SWIFT/BIC code are an ISO 3166-1 Alpha-2 country code identifying the country where the bank is registered. This is how the SWIFT network routes payments to the correct country.

Passports & Travel Documents

ISO 3166-1 Alpha-2 and Alpha-3 codes appear on the machine-readable zone of passports, visas, and identity cards worldwide, allowing automated border control systems to identify nationality.

Internet Country Domains (ccTLD)

Every country is assigned a country-code top-level domain based on its Alpha-2 code — .de for Germany, .fr for France, .cn for China. These are managed by IANA and are among the oldest domain suffixes on the internet.

Currency & Forex Trading

ISO 4217 currency codes (USD, EUR, GBP) are closely related to ISO 3166-1 — the first two letters of most currency codes correspond to the country's Alpha-2 code. Forex pairs like EUR/USD or GBP/JPY are built on this foundation.

Vehicle Registration Plates

International vehicle registration codes displayed on oval badges are based on ISO 3166-1 Alpha-2 codes. These are used across Europe, the Middle East, and many other regions to identify a vehicle's country of registration.

E-commerce & Shipping

Online retailers, payment gateways, and logistics companies use ISO 3166-1 codes to identify shipping destinations, calculate import duties, apply regional pricing, and comply with export regulations.

VAT & Tax Systems

EU VAT numbers begin with the two-letter ISO country code of the member state (e.g., DE for Germany, FR for France, GB for the UK pre-Brexit). Tax authorities and businesses use these codes to validate cross-border VAT registrations.

Global Currency Zones — Which Countries Share a Currency?

Many countries share a common currency rather than issuing their own. The most significant shared currency zones visible in the table above include:

🇪🇺 Euro (€) — Eurozone

35 countries / territories

The Euro is the official currency of the Eurozone — the 20 EU member states that have adopted it — plus several non-EU countries and territories that use it officially or unofficially. It is the world's second most traded currency after the US Dollar.

Åland Islands · Andorra · Austria · Belgium · Croatia · Cyprus · Estonia · Finland · France · French Guiana · French Southern Territories · Germany · Greece · Guadeloupe · Holy See · Ireland · Italy · Latvia · Lithuania · Luxembourg · Malta · Martinique · Mayotte · Monaco · Montenegro · Netherlands · Portugal · Réunion · Saint Barthelemy · Saint Martin (French) · Saint Pierre and Miquelon · San Marino · Slovakia · Slovenia · Spain

🇺🇸 US Dollar ($) — Dollarised Economies

17 countries / territories

The US Dollar is the world's primary reserve currency and is used as the official or de facto currency in many countries beyond the United States. Countries that have formally adopted the USD (dollarisation) include Ecuador, El Salvador, Panama, and several Pacific island nations.

American Samoa · Bonaire, Sint Eustatius and Saba · British Indian Ocean Territory · Ecuador · El Salvador · Guam · Marshall Islands · Micronesia · Northern Mariana Islands · Palau · Puerto Rico · Timor-Leste · Turks and Caicos Islands · United States · United States Minor Outlying Islands · Virgin Islands (British) · Virgin Islands (U.S.)

🌍 CFA Franc — West & Central Africa

14 countries

The CFA Franc is used across two currency unions in sub-Saharan Africa: the West African CFA Franc (XOF) used by 8 ECOWAS member states (Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal, Togo) and the Central African CFA Franc (XAF) used by 6 CEMAC member states (Cameroon, Central African Republic, Chad, Republic of Congo, Equatorial Guinea, Gabon). Both are pegged to the Euro.

🌊 East Caribbean Dollar (XCD)

8 countries

The East Caribbean Dollar is shared by 8 island nations and territories in the Eastern Caribbean: Antigua and Barbuda (AG), Anguilla (AI), Dominica (DM), Grenada (GD), Montserrat (MS), Saint Kitts and Nevis (KN), Saint Lucia (LC), and Saint Vincent and the Grenadines (VC). It is issued by the Eastern Caribbean Central Bank (ECCB) and pegged to the US Dollar at a fixed rate of 2.70 XCD = 1 USD.

How to Read and Use ISO 3166-1 Alpha-2 Codes

Alpha-2 codes are the most practical and widely recognised part of the ISO 3166-1 standard. Here are the key things to know when using them in financial, technical, or administrative contexts:

Always uppercase

ISO 3166-1 Alpha-2 codes are always written in UPPERCASE (e.g., DE, GB, US, AE). Lowercase versions (de, gb, us) are used exclusively for internet domain suffixes (ccTLDs) and are not the same as the official ISO codes.

Two letters, always

Alpha-2 codes are exactly two Latin letters. There are no one-letter or three-letter Alpha-2 codes. Three-letter codes belong to the separate ISO 3166-1 Alpha-3 standard (e.g., DEU for Germany, GBR for United Kingdom, USA for United States).

Not the same as currency codes

ISO 4217 currency codes (USD, EUR, GBP) are three letters and defined by a separate standard. While the first two letters of many currency codes match the country code (e.g., GB→GBP, AU→AUD), this is not always the case — the Euro (EUR) and several others are exceptions.

Some codes are reassigned

When countries dissolve or are renamed, their codes may be reassigned. For example, CS was previously used for Czechoslovakia, then for Serbia and Montenegro, and is now retired. The ISO 3166/MA publishes a newsletter each time a change is made.

Territories and dependencies

The standard covers not just independent states but also dependent territories, overseas regions, and special areas. This is why you see entries like Åland Islands (AX), Guam (GU), Puerto Rico (PR), and Gibraltar (GI) in the table above.

Country Code vs Dialling Code vs Currency Code — What’s the Difference?

The phrase “country code” is used loosely for several unrelated standards. This table shows what each one actually is, using Germany as a worked example:

Code type	Standard	Germany	Used for
Alpha-2 country code	ISO 3166-1	DE	IBANs, SWIFT codes, VAT numbers, software locales
Alpha-3 country code	ISO 3166-1	DEU	Passports, sports events, statistical databases

Frequently Asked Questions About Country Codes

What is an ISO 3166-1 country code?

ISO 3166-1 is the international standard that assigns each country a short code. It defines three formats: a two-letter alpha-2 code (DE), a three-letter alpha-3 code (DEU) and a three-digit numeric code (276). Alpha-2 codes are the ones used in IBANs, domain names and most software.

What is the difference between alpha-2 and numeric country codes?

Alpha-2 codes are two letters and are the most widely used — they appear in IBANs, internet domains and currency pair notation. Numeric codes are three digits and are language-independent, which makes them useful in systems that do not use the Latin alphabet.

Which country code is used in an IBAN?

An IBAN begins with the ISO 3166-1 alpha-2 code of the country where the account is held — DE for Germany, FR for France, AE for the United Arab Emirates. It is always the first two characters of the IBAN.

What is a ccTLD?

A ccTLD (country code top-level domain) is the internet domain suffix assigned to a country or territory, such as .de for Germany or .jp for Japan. Most are derived directly from the ISO 3166-1 alpha-2 code.

How many countries are in the ISO 3166-1 standard?

The standard covers 249 country and territory entries, which includes sovereign states as well as dependent territories and special areas of geographical interest.

Which countries use the euro?

The euro is the official currency of the eurozone member states and is also used in several territories and microstates. The currency groupings section on this page lists every entry in this directory that uses the euro.

What is the country code for Germany?

Germany's ISO 3166-1 alpha-2 code is DE. Its alpha-3 code is DEU and its numeric code is 276. The country-code top-level domain is .de, and every German IBAN begins with DE. Note that +49 is Germany’s international dialling code, which comes from a different standard.

Is a country code the same as a phone dialling code?

No. ISO 3166-1 country codes are letters or digits used to identify countries in banking, domains and databases. International dialling codes such as +49 for Germany or +1 for the United States come from ITU-T Recommendation E.164, a separate telecommunications standard. The two are unrelated and the values do not match.

Is the code for the United Kingdom GB or UK?

GB is the official ISO 3166-1 alpha-2 code for the United Kingdom. UK is exceptionally reserved within the standard at the United Kingdom’s request, which is why the internet domain is .uk while IBANs, SWIFT codes and passports all use GB.

What is the difference between ISO 3166-1 and ISO 3166-2?

ISO 3166-1 codes identify countries and territories. ISO 3166-2 codes identify subdivisions within them — states, provinces, regions — and are written as the country code, a hyphen, then the subdivision code, such as DE-BY for Bavaria or US-CA for California. ISO 3166-3 records codes that were used by countries that no longer exist.

Are country codes and currency codes the same thing?

No. Currency codes come from ISO 4217 and are three letters, such as USD, EUR or JPY. For many currencies the first two letters match the country’s alpha-2 code — GB gives GBP, JP gives JPY — but there are exceptions, most notably the euro (EUR), which is shared across many countries.
