CLLI (Common Language location identifier) codes identify elements of the North American telephone network. In Montréal (NPA 514), Bell Canada uses the following codes for central offices (exchanges) where switches are located. The area served by a central office is a wire centre. Rate centres are the basis of local calling areas and long distance charges.
The 2 Letter 5 Digit column shows current assignments of the 2L-5D named prefixes that have existed since the 1950s. Some wire centre boundaries and prefixes have changed over time. Most central offices now use additional prefixes.
