ISO 639-2:1998, Codes for the representation of names of languages — Part 2: Alpha-3 code, is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. The three-letter codes given for each language in this part of the standard are referred to as "Alpha-3" codes. There are 464 language codes in the list.

The U.S. Library of Congress is the registration authority for ISO 639-2 (referred to as ISO 639-2/RA). As registration authority, the LOC receives and reviews proposed changes; they also have representation on the ISO 639-RA Joint Advisory Committee responsible for maintaining the ISO 639 code tables.

Work was begun on the ISO 639-2 standard in 1989, due to the fact that the ISO 639-1 standard, which gives two-letter codes for languages, would not be able to accommodate a sufficient number of languages. The ISO 639-2 standard was first released in 1998.

[edit] B and T codes

While most languages are given one code by the standard, twenty of the languages described have two three-letter codes, a "bibliographic" code (ISO 639-2/B), which is derived from the English name for the language and was a necessary legacy feature, and a "terminological" code (ISO 639-2/T), which is derived from the native name for the language. Each of these twenty languages is also included in the ISO 639-1 standard. (There were 22 B codes; scc and scr are now deprecated.)

In general the T codes are favored; ISO 639-3 uses ISO 639-2/T. However, ISO 15924 derives its codes when possible from ISO 639-2/B.

[edit] Scopes and types

Scopes:

Individual languages
Macrolanguages
Collections of languages
Dialects
Reserved for local use
Special situations

Types (for individual languages):

Living languages
Extinct languages
Ancient languages
Historic languages
Constructed languages

[edit] Special situations

There are codes for special situations:

mis is listed as "uncoded languages"
mul (for multiple languages) is applied when several languages are used and it is not practical to specify all the appropriate language codes
The interval from qaa to qtz is reserved and is not used in the standard
und (for undetermined) is used in situations in which a language or languages must be indicated but the language cannot be identified.
zxx is listed in the code list as "no linguistic content" (added 2006-01-11)

[edit] Collective language codes

Some ISO 639-2 codes that are commonly used for languages do not precisely represent a particular language or some related languages (as the above macrolanguages). They are regarded as collective language codes and are excluded from ISO 639-3.

For a definition of macrolanguages and collective languages see [1].

The collective language codes in ISO 639-2 are listed below.

The following two codes are not (yet) identified as collective codes in ISO 639-2 (and ISO 639-5), but are identified as such by the ISO 639-3 registry:

bih Bihari (has the ISO 639-1 code bh)
him Himachali
