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

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

Special situations

There are codes for special situations:
  • mis is listed as "uncoded languages"

  • 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)

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
