History of the 317 Area Code

Why the Overlay Is 463
The overlay code was picked with a small local touch. On a phone keypad, 4-6-3 spells “IND”, short for Indianapolis and Indiana. New lines in the area may be given 463, which is just as local as 317.
Indiana’s clocks are also worth a note. The Indianapolis area is on Eastern Time, while the northwest and southwest corners of the state are on Central Time.

Is a Call From 317 a Scam?
A 317 number is normally a household or employer in the Indianapolis area. The city is a center for health care, insurance, logistics and motorsports, and customer service calls from 317 are common.
Watch for these warning signs:
- Threats of arrest, a lawsuit or a service shut-off unless you pay today
- Offers of a prize, a loan or a job that need a fee first
- Callers who already know part of your details and ask you to “confirm” the rest
- One-ring calls that try to make you call back
Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.
