IRG Document Register

The table below provides hyperlinks to all IRG document registers, organized in ranges of 250 document numbers. Note that documents created before IRG N2700 may include hyperlinks to the documents in the previous IRG document register, which may become inaccessible in the future.

The process of migrating the available IRG documents began on 2024-07-08, and was completed on 2026-02-14. The rows for unavailable documents are highlighted in yellow. The status of an estimated 700 early IRG documents, generally those below IRG N1061, is unknown. Those documents are marked as (unknown). Some document numbers were never used, which are marked as (unused). Three documents — IRG N105, IRG N117, and IRG N182 — were withdrawn, which are marked as (withdrawn). Some older documents correspond to WG 2, X3L2, or L2 documents, but because the migration of those documents is incomplete, those documents are not available (the corresponding WG 2, X3L2, or L2 document numbers are shown in brackets).

Duplicate Document Numbers

Six IRG document numbers — IRG N1022 through IRG N1027 — were each assigned to two completely unrelated documents for IRG Meeting #21 and IRG Meeting #22. The same is true for IRG N1110, which was assigned to two completely unrelated documents for IRG Meeting #23 and IRG Meeting #24. IRG N1129, IRG N1168, and IRG N1224 were also assigned to two completely unrelated documents, and IRG N1210 was assigned to three completely unrelated documents. The rows for the duplicate document number assignments are shaded in gray on the IRG Document Register for 1001–1250 page.

Document Search

This form can be used to find IRG documents by their document number, if available in this IRG document register, and will generate a page containing links to all available documents, to include revisions, if any. Using fewer digits will find documents whose document numbers begin with the specified digits. For example, entering 272 will find documents IRG N2720 through N2729.

IRG documents can also be searched by using the following URL, followed by one to four digits, which will behave exactly like the form above: https://www.unicode.org/cgi-bin/GetMatchingIRGDocs.pl?

Key Historical Documents

While all IRG documents are considered historical, hence the purpose of this document register, the following are considered key historical IRG documents or national standards in the sense that they are no longer maintained or are difficult to find, but can serve as research material:
