A language code is a short, standard identifier for a language, such as en for English, es for Spanish or de for German. These two-letter codes come from ISO 639-1, which has 183 of them. ISO 639-2 adds three-letter codes (eng, spa, deu) for many more languages. Software adds a region when it matters, as in en-US or es-MX.

The mistake to watch for is a country code typed in place of a language code. SE is Sweden’s country code, but as a language code, se means Northern Sami.

What are the codes for the most-used languages?

Here are the two-letter code (ISO 639-1), the three-letter code (ISO 639-2) and a few example tags with a region or script added for 11 common languages. Some languages have a second three-letter code, called the bibliographic code. It’s in parentheses.

Language	ISO 639-1	ISO 639-2	Example tags
English	en	eng	en-US, en-GB, en-AU
Spanish	es	spa	es-ES, es-MX, es-419 (Latin America)
French	fr	fra (fre)	fr-FR, fr-CA
German	de	deu (ger)	de-DE, de-AT, de-CH
Portuguese	pt	por	pt-BR, pt-PT
Italian	it	ita	it-IT
Russian	ru	rus	ru-RU
Chinese	zh	zho (chi)	zh-Hans (Simplified), zh-Hant (Traditional), zh-CN, zh-TW
Japanese	ja	jpn	ja-JP
Korean	ko	kor	ko-KR
Arabic	ar	ara	ar-SA, ar-EG

So US English is en-US, and Spanish is es, never sp. The full lists of two-letter and three-letter codes are further down.

Which country codes are mistaken for language codes?

Country codes (ISO 3166-1) and language codes (ISO 639-1) are both two letters, so they get swapped. Some country codes aren’t language codes at all, and a check against the language registry rejects them. Others are worse: they’re valid codes for a different language, so nothing fails and the wrong language label ships.

Country code	That code as a language code	The code you meant
SE (Sweden)	se = Northern Sami	sv (Swedish)
KR (South Korea)	kr = Kanuri	ko (Korean)
BR (Brazil)	br = Breton	pt-BR (Portuguese in Brazil)
CH (Switzerland)	ch = Chamorro	de-CH, fr-CH, it-CH
BE (Belgium)	be = Belarusian	nl-BE, fr-BE, de-BE
EE (Estonia)	ee = Ewe	et (Estonian)
SI (Slovenia)	si = Sinhala	sl (Slovenian)
AM (Armenia)	am = Amharic	hy (Armenian)
LU (Luxembourg)	lu = Luba-Katanga	lb (Luxembourgish)
LA (Laos)	la = Latin	lo (Lao)
TW (Taiwan)	tw = Twi	zh-TW or zh-Hant
KG (Kyrgyzstan)	kg = Kongo	ky (Kyrgyz)

These country codes aren’t ISO 639-1 codes at all: jp (Japanese is ja), cn (Chinese is zh), dk (Danish is da), gr (Greek is el), cz (Czech is cs), ua (Ukrainian is uk) and vn (Vietnamese is vi). And British English is en-GB, not en-UK. The country code for the United Kingdom is GB, and uk on its own means Ukrainian.

What’s the difference between ISO 639-1, 639-2 and 639-3?

ISO now publishes these code sets as one standard, ISO 639:2023. Most people and tools still call them 639-1, 639-2 and 639-3.

Code set	Letters	What it covers	German
ISO 639-1	2	Major, mostly national languages	de
ISO 639-2	3	A larger list of widely known languages, plus some language groups	deu
ISO 639-3	3	All individual languages, living, extinct and ancient	deu

For 20 languages, ISO 639-2 lists two three-letter codes: a bibliographic (B) code such as ger for German and a terminology (T) code such as deu. ISO 639-3 uses deu as well. All 20 of these languages also have a two-letter code.

Which language code should software use?

On the web, language tags follow BCP 47, defined in RFC 5646. Its rules cover most cases:

Use the two-letter ISO 639-1 code when a language has one: de, not deu or ger.
Use the three-letter code only for languages without a two-letter code, such as fil (Filipino) or haw (Hawaiian).
Add a region only when your content differs by region. The region is an ISO 3166-1 country code (en-GB, pt-BR) or a three-digit UN M.49 area code (es-419 for Latin America and the Caribbean).
Case doesn’t change the meaning, but the convention is a lowercase language code and an uppercase region: en-US, not EN-us.

Then pick one tag per locale and use it everywhere: in your code, your translation files and your translation management system. Our guide to ISO language codes in software covers how to store tags, validate them and set up fallbacks between locales.

What is ISO 639-2?

ISO 639-2 is the list of three-letter codes, first published in 1998. The Library of Congress maintains it.

Which languages does ISO 639-2 include?

The ISO 639-2 language standard includes:

Individual languages
Macrolanguages - a group of linguistically varied dialects within one “umbrella language“.
Language collections - or collective language codes refer to languages which have a similarity, but not a high enough level of similarity to be considered dialects (example, Germanic, Slavic languages)
Special situations

Special situations group include 4 generic codes, which are also present in the ISO 639-3 standard:

mis - uncoded or miscellaneous languages
mul - when several languages are used simultaneously
und - undetermined, when a language is not identified
zxx - non linguistic content, such as onomatopoeia (animal sounds)
