How to Get a 317 Phone Number

There are three ways to get a phone number with the 317 area code, each suited to a different need:

  1. Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 317 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 317 inventory.
  2. Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 317 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.
  3. Port an existing 317 number. If you already have a 317 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 Indiana sometimes can’t accept inbound ports of 317 numbers due to 911 routing rules.

Is 317 a scam area code?
No. 317 is a legitimate, active area code for Indianapolis metropolitan area and nine surrounding counties in central Indiana. Like any area code, scammers occasionally spoof 317 caller IDs, but the code itself is heavily used by real Indiana businesses, government offices, and residents.

Do I need to dial 10 digits when calling a 317 number locally?
Yes. Since the 463 overlay was introduced in 2016, ten-digit dialing — area code plus the seven-digit number — is mandatory for all local calls within the 317/463 region.

Is 317 one of the original area codes?
Yes. Area code 317 was established in 1947 as one of the original 86 North American Numbering Plan area codes, initially serving the northern two-thirds of Indiana before being reduced to central Indiana in 1948.

Why was area code 463 added to the same region as 317?
Growth in mobile phones and other devices exhausted available numbers in the 317 area code, which was projected to run out by 2017. Rather than forcing existing customers to change numbers via a geographic split, regulators added 463 as an overlay in 2016, covering the identical territory.
