Area Code 354
(418 and 581 and 367) - (450 and 579)
(514 and 438) - (819 and 873)
Area Code 354 History:
Area code 354 has been assigned as a distributed overlay of area codes 450/579 in the geographic area surrounding Montreal, Quebec. The original planned implementation date 10/24/2020 has been postponed.
Area code 354 will be implemented at a future date when the area code overlay is needed. Ten digit dialing (area code + seven digit number) will necessary in the 354/450/579 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
