What is the International Morse Code Reference (2026)?
The International Morse Code Reference (2026) is the complete, dated table of every letter, digit, and punctuation mark assigned under ITU-R M.1677-1, the International Telecommunication Union's Morse code standard, current as of July 2026. It lists 26 letters, 10 digits, and 18 punctuation marks, each as a fixed sequence of dots and dashes, with no ambiguity between entries. The assignments have not changed since the ITU's October 2009 revision consolidated earlier editions, and no replacement is scheduled, so this table has been stable for close to two decades. Amateur radio operators, aviation VOR beacon systems, and assistive-technology input tools still rely on this exact table today. It is also the same mapping this site's own translator uses internally to convert text in both directions, so the printed reference and the working tool are guaranteed to agree, character for character.
Summary table
All 54 characters. The morse_code column uses a period for a dot and a hyphen for a dash, matching the plain-text convention used throughout this site.

Methodology
Where these codes come from
Every code in this table is taken from Recommendation ITU-R M.1677-1, "International Morse code" (October 2009), published by the International Telecommunication Union's Radiocommunication Sector. That recommendation is the current edition still in force in 2026; it consolidated earlier ITU Morse code recommendations and has not been superseded. The table above was cross-checked this session against this site's own translator (the same lookup used by the tool on the homepage), so the reference page and the working tool cannot drift apart.
When this page was last updated
dateModified: 2026-07-08
This page is reviewed whenever the site's calculator logic changes or the ITU publishes a new revision, whichever comes first. Because the standard itself has been stable since 2009, updates here are expected to be about presentation, not the codes themselves.
