Area Code 457

Area code 457 is one of the newest NANP area codes

Area code 457 is one of the most recently added codes in the North American Numbering Plan, in service since September 25, 2025. It is an overlay that shares its territory with 318, adding fresh numbers as those codes fill up. Existing numbers in the area keep their codes; only new phone lines may be issued a 457 number.

Because 457 is new and unfamiliar, some people are wary when it appears on caller ID and search for “who called me from 457?” An area code only shows where a number is registered, and any number can be spoofed — so a 457 call is not suspicious on its own. Judge each call by what it asks for, not the code. Is a call from 457 a scam?

Is a call from area code 457 a scam?

A 457 number is geographically tied to Louisiana, 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 457 a country code?

No. 457 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 457 number written for international dialing looks like +1 457 followed by the 7-digit local number.
