Area Code 428

Area code 428 is one of the newest NANP area codes

Area code 428 is one of the most recently added codes in the North American Numbering Plan, in service since April 29, 2023. It is an overlay that shares its territory with 506, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 428 number.

Because 428 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 428?” An area code only shows where a number is registered, and any number can be spoofed — so a 428 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 428 a scam?

Is a call from area code 428 a scam?

A 428 number is geographically tied to New Brunswick, 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 428 a country code?

No. 428 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 428 number written for international dialing looks like +1 428 followed by the 7-digit local number.
