Established on October 19, 1943, as a part of the Ceylon Defence Force^[2] it was reformed as a troop of signals February 9, 1950 following the formation of the Ceylon Army in 1949. The initial task of this troop was to provide communications between Army HQ and its branches. In 1949, the Volunteer Signals unit was commanded by Lt Col CR De Silva. By the end of 1950 this troop had 1 Officer and 17 other ranks and their tasks included establishing a signals office at Army HQ, provision of a signal dispatch service, manning a switch board and the construction and maintenance of underground as well as field cables. In May 1951 another Signals Office was established in Diyatalawa to serve the Garrison HQ which was just formed at that time. By October 1, 1951, the troop was raised to a squadron with a strength of 4 officers and 142 other ranks.

In 1951 formal approval was granted to wear the Royal Signals badges with the additional scroll "CEYLON" on it and to adopt the Royal Signals march Begone Dull Care as the regimental march of the Ceylon Signals Corps and in 1959 the 1st Regiment of the Ceylon Signals was formed with Lt Col DV Brohier was appointed as its first Commanding Officer. In 1962 following the attempted military coup the 2nd volunteer signal regiment was disbanded and its remaining personnel transferred to form the National Service Regiment (NSR).

In 1972 with Sri Lanka proclaiming itself a republic, the Corps was renamed as the Sri Lanka Signals Corps. In 1980 a new Volunteer squadron was raised. The Corps has expanded to a level of a Signals Brigade with integral signals units under HQ Chief Signal Officer at the highest level of command in performing the classic role. The Signals Corps provides support to the combat and support arms by providing communications, electronic warfare and information technology support in the battle field and at the rear. All these signal units and sub-units administratively come under the aegis of the Regimental Centre located at Panagoda Cantonment.

The corps also runs a School of Signals^[3] in Kandy, established on 15 July 1991. The school is currently under the command of Col SJKD Jayawardena USP psc, with Major KVA Kodikara psc serving as chief instructor. The Sri Lanka Army established a Directorate of Information Technology under the Signal Corps on 1 March 2010; its current director is Major General P A J Peiris ndu.
