The Deep Dive: Why Does Indianapolis Have Two Area Codes?
The existence of two Indianapolis, Indiana area codes for the same location can be confusing. The story of how area 463 joined 317 is a story of population growth and the changing demands of modern technology.
A Brief History of Area Code 317
The 317 area code is one of the original area codes created in 1947. Initially, it covered the entire northern two-thirds of Indiana. As the population grew and more phone lines were needed, the area was split. The most recent split occurred in 1997, which isolated the 317 area code to its current footprint around Indianapolis.
The Rise of a New Number: The 2016 Introduction of Area Code 463
By the 2010s, the demand for new phone numbers from cell phones, tablets, and VoIP services was causing the 317 area code to run out of available numbers. To solve this, regulators implemented an “overlay” in 2016.
An overlay introduces a new area code—in this case, the 463 area code Indiana—to the same geographic territory as the existing one. This meant that new phone numbers could be assigned with the areacode 463 prefix, while everyone with a 317 number could keep it. This solution avoided forcing half the residents and businesses in the metro area to change their numbers.
However, this change came with one major new requirement: mandatory 10-digit dialing. Since 2016, every local call made within the Indianapolis area must include the area code, even if you are calling a number with the same prefix.
A Clever Mnemonic: How 463 Spells “IND”
The choice of the number for the area code for 463 was clever. On a telephone keypad, the numbers 4-6-3 correspond to the letters I-N-D, a common abbreviation for Indianapolis and the city’s airport code.
Clearing Up Confusion: Area Code vs. ZIP Code vs. Country Code
Search queries often show confusion between different types of numerical codes. It’s important to understand the difference.
Is 463 a ZIP Code?
No. A common mistake is to search for the “463 zip code.” The 463 area cose is a telephone code used to route calls. A ZIP Code is a postal code used by the USPS to route physical mail. They are completely different systems. An office in Indianapolis might be in ZIP code 46204 and have a 463 area code phone number.
Is 463 a Country Code?
No, the 463 country code does not exist. It is a local area code within the United States. The country code for the USA (and all of North America) is +1. To call an Indianapolis number from another country, you would dial +1, then 463 or 317, and then the seven-digit phone number. So, for anyone searching “area 463 estados unidos,” the number to dial first is +1.
