ITU-T is one of the three Sectors (divisions or units) of the International Telecommunication Union (ITU).

The standardization efforts of ITU started in 1865 with the formation of the International Telegraph Union (ITU). ITU became a Specialized agency of the United Nations in 1947. The International Telegraph and Telephone Consultative Committee (French: Comité Consultatif International Téléphonique et Télégraphique, CCITT) was created in 1956, and was renamed ITU-T in 1993.

ITU-T has a permanent secretariat, the Telecommunication Standardization Bureau (TSB), based at the ITU headquarters in Geneva, Switzerland. The current director of the bureau is Chaesub Lee, whose first 4-year term commenced on 1 January 2015, and whose second 4-year term commenced on 1 January 2019.
