IPA number

100: IPA consonants

Current IPA consonants, and those retired after the Kiel convention, are assigned numbers in the 100 range. The tie-bars used to create affricate consonants are assigned numbers in the 400 and 500 ranges.

200: retired and non-IPA consonants

The 200 range is mostly retired IPA consonants, though it includes several letters of the Americanist Phonetic Alphabet that are sometimes used alongside the IPA. A few superscript IPA letters, including a single vowel, have also been assigned numbers in this range. Symbols official until retirement by Kiel in 1989 are numbered upwards from 201; those already retired, or not IPA at all, are numbered downwards from 299.

In addition, there is the pre-composed character , the loop-tail (see the main consonant chart above), and the implicit IPA letter .

300: IPA vowels

Vowel letters that were official after Kiel were numbered upward from 301. , which was once needed to create with a diacritic, two letters retired at Kiel, , and the three non-rhotic vowels added in the 1993 and 1996 updates to the IPA, , were numbered downward from 399. Pre-composed , present at Kiel, was assigned a number, but later and were not.

400: non-tone diacritics

500: suprasegmentals

Indicators of tone, stress, intonation and other elements of prosody. Combinations of tone diacritics or letters that were illustrated on the IPA Chart in 1999 are assigned individual numbers, leaving 3 tone diacritics and many, many compound tone letters without assigned numbers.

600: extIPA

The symbols of the Extensions to the IPA were numbered sequentially to 683. Several are redundant with other ranges. (The capital Latin letters are not shown here; see the 700 range.) A few letters that were apparently added to extIPA after 1999, such as , were not given numbers either, though they predate , which was added to the regular IPA in 2005 and did receive a number. The symbols added in the 2015 expansion of extIPA were apparently never assigned numbers either.

Number 611 is the "balloon" used to encircle unidentified segments.

700: capital letters

The capitals of the basic Latin alphabet, A–Z, are assigned the numbers 701 to 726 in order.

C 703, F 706, J 710, L 712, V 722 and W 723 are redundant with their extIPA numbers 624, 622, 626, 625, 621, 623, respectively.

900: transcription delimiters

Brackets and other punctuation that mark linguistic transcription
