463 Area Code: Indianapolis, Indiana

Indiana's 463 area code is an overlay layered onto the same central Indiana footprint long served by the 317. Indianapolis anchors the directory's records here, set on a flat plain divided by the White River roughly in the middle of the state. The 463 designation, part of the North American Numbering Plan, has been filling with allocations as central Indiana's number demand has continued to push past what 317 alone could carry. The footprint covers the city itself along with Carmel, Fishers, Greenwood, and the surrounding cluster of suburban communities.

In records the directory has compiled for 463 numbers, other Indiana cities — Evansville, Fort Wayne, Hammond, and Lafayette — appear regularly. None of those are inside the 463 footprint. The pattern reflects standard public-record dynamics across Indiana. The directory currently documents 24 distinct prefixes within 463 in detail, an early-stage subset that should be read as a working slice of the prefix population the code will eventually carry.

Indianapolis's home values come in below the US median, with median household income running below the national figure but not severely so. The city's median age sits a few years under the US reading, and population places Indianapolis among the larger cities in the Midwest — substantial enough to anchor a metropolitan area that pulls steadily on populations from across central Indiana. The 463 footprint shares those demographics with 317 because both codes serve central Indiana in overlapping form.
