Indiana has 8 active area codes as of 2026, covering the state through a mix of original 1947 assignments, geographic splits, and modern overlays. This guide walks through the full list, which regions each code serves, the order they came online, and where new codes are most likely to land next.
The Short Answer
Indiana currently has 8 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Indiana ranks #17 nationally with roughly 6,924,275 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Full List of Indiana Area Codes
The active area codes serving Indiana are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.

- 260 — Northeast Indiana (Fort Wayne, Angola) (split from 219)
- 317 — Indianapolis metro (Marion, Hamilton, Hendricks, and surrounding counties)
- 463 — Indianapolis metro (overlay of 317)
- 574 — North-central Indiana (South Bend, Elkhart, Warsaw) (split from 219)
- 765 — Central Indiana outside Indianapolis (Lafayette, Muncie, Kokomo, Richmond, Anderson)
- 812 — Southern Indiana (Evansville, Bloomington, Terre Haute, Columbus)

How Indiana’s Area Codes Grew Over Time
Indiana was assigned 2 area codes in the original 1947 NANP launch — 317, 812 — reflecting the state’s population and territorial size at the time. Subsequent splits and overlays have added codes as demand has grown.

Browse Indiana Area Codes →- 1947 — Indiana received two area codes at the launch of the North American Numbering Plan: 317 for the northern two-thirds of the state including Indianapolis, and 812 for the southern third.
- 1948 — 219 split off from 317 to cover the northern third of the state, including Gary, Hammond, South Bend, and Fort Wayne.
- 1997 — 765 split off from 317 for central Indiana outside the Indianapolis metro (Lafayette, Muncie, Kokomo, Richmond, Anderson).
- 2002 — 219 was divided in a three-way split: the northwest corner kept 219, while 260 was created for northeast Indiana (Fort Wayne) and 574 for north-central Indiana (South Bend).
- 2015 — 930 became Indiana's first overlay code, joining 812 across southern Indiana; first numbers were assigned March 7, 2015 after the overlay was announced in 2013.
- 2016 — 463 activated as an overlay of 317 in the Indianapolis metro, making ten-digit dialing mandatory there.
Why Indiana Has Multiple Area Codes
A single area code can hold roughly 7.9 million possible phone numbers in theory — 792 valid central office codes (the second three digits) multiplied by 10,000 line numbers each. In practice the usable count is lower, because blocks of numbers are reserved, withheld, or assigned in bulk to carriers that may never fully use them. When the pool of available numbers in an area code falls below the threshold the North American Numbering Plan Administrator (NANPA) tracks, the state requests relief, and either a split or an overlay is approved.
Indiana’s population of roughly 6,924,275 residents would, on its own, fit comfortably inside a single area code’s capacity. The reason 8 codes are needed instead is that every adult typically carries at least one mobile line, many households have multiple lines per person, businesses concentrate phone numbers at extreme density, and connected devices, VoIP services, and second-line apps all draw from the same pool. The math compounds quickly.
Indiana Area Codes by Region
Indianapolis metro (317, 463): Marion County plus Boone, Hancock, Hamilton, Hendricks, Johnson, Madison, Morgan, and Shelby counties. 317 is the original 1947 code; 463 overlay was added in 2016.
Central Indiana (765): A horseshoe-shaped region around Indianapolis including Lafayette, Muncie, Kokomo, Richmond, and Anderson. Split off from 317 in 1997.
Northwest Indiana (219): The Indiana side of the Chicago metropolitan area: Gary, Hammond, Merrillville, Valparaiso, and Michigan City. Split off from 317 in 1948; retained 219 after the 2002 three-way split.
North-central Indiana (574): South Bend, Elkhart, and Warsaw. Created in 2002 when the original 219 territory was split three ways.
Northeast Indiana (260): Fort Wayne and Angola. Created in 2002 from the eastern portion of the former 219 region.
Southern Indiana (812, 930): The southern third of the state: Evansville, Bloomington, Terre Haute, Columbus, and the Indiana suburbs of Louisville and Cincinnati. 812 is the original 1947 code; 930 overlay was added in 2015.
What’s Next for Indiana Area Codes
Indiana’s two overlay activations — 930 over 812 in 2015 and 463 over 317 in 2016 — addressed the two regions under the most pressure, and the 2002 three-way split of 219 gave the northern third of the state ample headroom. NANPA’s recent NPA exhaust projections show no Indiana numbering plan area on the near-term relief schedule. The Indianapolis metro (317/463) is the most likely candidate for the next overlay as population continues to concentrate there, but no additional relief is currently projected for the state in the near future.
Frequently Asked Questions
How many area codes does Indiana have right now?
Indiana has 8 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Indiana?
317 is the oldest active area code in Indiana, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Indiana?
The most recent area code addition to Indiana was 463, activated in 2016. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Indiana need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
Which area codes cover Indianapolis?
Indianapolis and its nine surrounding counties are served by 317, the original 1947 code, and 463, an overlay added in 2016. Both cover the same geography, so new lines in the metro may be assigned either one, and ten-digit dialing is required for all local calls.
What area code does Fort Wayne use?
Fort Wayne uses 260, which was created in 2002 when the old 219 region in northern Indiana was split into three. Before 2002, the entire northern third of the state used 219.
Is 930 a real Indiana area code?
Yes. 930 is an overlay of 812 covering the southern third of Indiana, including Evansville, Bloomington, and Terre Haute. It went into service in 2015 and was the first overlay code in the state, so southern Indiana numbers may begin with either 812 or 930.
Why did Indiana split the 219 area code into three?
By the early 2000s, the original 219 covering all of northern Indiana was running low on available prefixes, driven by population and cell phone growth. In 2002 the territory was divided into three: 219 was kept in the northwest, 574 was created for the South Bend area, and 260 for the Fort Wayne area.
