Area Code 742

Area code 742 is one of the newest NANP area codes

Area code 742 is one of the most recently added codes in the North American Numbering Plan, in service since October 16, 2021. It is an overlay that shares its territory with 289, 365, 905, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 742 number.

Because 742 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 742?” An area code only shows where a number is registered, and any number can be spoofed — so a 742 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 742 a scam?

A 742 number is geographically tied to Ontario, 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.

No. 742 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 742 number written for international dialing looks like +1 742 followed by the 7-digit local number.
