Area code 350 is one of the newest NANP area codes
Area code 350 is one of the most recently added codes in the North American Numbering Plan, in service since November 28, 2022. It is an overlay that shares its territory with 209, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 350 number.
Because 350 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 350?” An area code only shows where a number is registered, and any number can be spoofed — so a 350 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 350 a scam?

Is 350 a country code?
No. 350 is a US area code (a domestic 3-digit code), not a country code. The country (calling) code for the United States is +1, shared across the North American Numbering Plan. So a full 350 number written for international dialing looks like +1 350 followed by the 7-digit local number.
