About area code 382
Area code 382 is a Canadian numbering plan area covering Southwestern Ontario (third overlay). It was placed into service in 2023 as a overlay code, and today operates under the Eastern Time (EST/EDT, UTC-5/-4) time zone.
Numbers in the 382 NPA are issued in central office (CO) blocks of 10,000 to local exchange carriers, who then assign them to subscribers. Because Canada uses a competitive carrier model under CRTC oversight, multiple carriers — both incumbent and competitive — hold blocks within 382. The current carrier of record for any specific number can be looked up via the Canadian Local Number Portability Consortium, but the originally issued carrier is no longer a reliable signal of who actually serves that line.
If you receive a call from a number beginning with 382, the caller is either physically located in or has historically been associated with Southwestern Ontario (third overlay). The same applies to overlay codes 519, 226, 548: any of these area codes can correspond to a phone in the same geography, and many households carry numbers from two or three different overlays simultaneously across landlines and mobile devices.
To call a number in 382 from outside Canada and the United States, dial your country's international access prefix, then +1 382 followed by the 7-digit local number. Within the NANP, simply dial 1 followed by all 10 digits — or just the 10 digits if you are also located in an overlay region where 7-digit local dialling is no longer permitted.
