Area Code 354

Area code 354 is one of the newest NANP area codes

Area code 354 is one of the most recently added codes in the North American Numbering Plan, in service since October 22, 2022. It is an overlay that shares its territory with 450, 579, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 354 number.

Because 354 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 354?” An area code only shows where a number is registered, and any number can be spoofed — so a 354 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 354 a scam?

Is a call from area code 354 a scam?

A 354 number is geographically tied to Quebec, but caller ID can be spoofed, so the displayed area code does not prove where a caller really is. If you did not expect the call, do not share personal information and consider looking the number up.

Is 354 a country code?

No. 354 is a Canadian area code (a domestic 3-digit code), not a country code. The country (calling) code for Canada is +1, shared across the North American Numbering Plan. So a full 354 number written for international dialing looks like +1 354 followed by the 7-digit local number.
