Companies that hold curated inventories of specific area codes can sell you a 457 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Browse our 457 inventory.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 457 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 457 number. If you already have a 457 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Louisiana sometimes can’t accept inbound ports of 457 numbers due to 911 routing rules.

Is 457 a scam area code?
No. 457 is a legitimate, active area code for Northern and central Louisiana, including Shreveport, Monroe, Alexandria, and surrounding parishes. Like any area code, scammers occasionally spoof 457 caller IDs, but the code itself is heavily used by real Louisiana businesses, government offices, and residents.
What is the 457 area code?
Area code 457 is a telephone area code serving northern and central Louisiana. It launched on September 25, 2025, as an overlay to the existing 318 area code, meaning both codes cover the same geographic region.
Why was the 457 area code created?
NANPA projected that area code 318 would exhaust its available numbers by early 2026. The Louisiana Public Service Commission approved the 457 overlay in May 2023 to ensure enough new numbers for the region without requiring existing customers to change their numbers.
Do I need to dial 10 digits when calling a 457 number?
Yes. Since September 25, 2025, all local calls within the 318/457 region require 10-digit dialing — the area code plus the 7-digit number. Seven-digit dialing is no longer accepted.
Will my existing 318 number change because of 457?
No. Existing 318 customers keep their numbers. Only new lines or services activated after September 25, 2025, may be assigned a 457 number.
