About: CLLI code

CLLI code (sometimes referred to as CLLI name or COMMON LANGUAGE Location Identifier Code, and often pronounced as silly) is a Common Language Information Services identifier used within the North American telecommunications industry to specify the location and function of telecommunications equipment or of a relevant location such as an international border or a supporting equipment location, like a manhole or pole. Originally, they were used by Bell Telephone companies, but since all other telecommunications carriers needed to interconnect with the dominant Bell companies, CLLI code adoption eventually became universal. CLLI codes are now maintained and issued by iconectiv, which claims trademarks on the names "Common Language" and "CLLI".
