History
The North American Numbering Plan was created in 1947 to organise telephone numbers across the United States, Canada and neighbouring regions. When an area runs out of phone numbers, the North American Numbering Plan Administrator (NANPA) either splits the area or adds an overlay code that covers the same area; overlays are now the usual approach, which is why 10-digit dialing is standard in most places. Area code 463 serves Indianapolis (overlay of 317).
How to dial 463
From the United States or Canada, dial 1 + 463 + the 7-digit number. From abroad, dial your international prefix, then 1 + 463 + the number — for example, +1 463 555 0132.
Is a call from 463 a scam?
Scammers can fake any area code, including 463. A number that looks local is not proof of who is calling. Never share passwords, verification codes or payment details with an unexpected caller; hang up and call the company back on a number from its official website. Report scam calls at reportfraud.ftc.gov, and forward spam texts to 7726.
