The numbering plan area comprises a [horseshoe-shaped](/source/Horseshoe-shaped) region of twenty counties in Central Indiana except for the [Indianapolis](/source/Indianapolis) area, which is served by [area codes 317 and 463](/source/Area_codes_317_and_463). Some cities included are [Anderson](/source/Anderson%2C_Indiana), [Connersville](/source/Connersville%2C_Indiana), [Crawfordsville](/source/Crawfordsville%2C_Indiana), [Frankfort](/source/Frankfort%2C_Indiana), [Greencastle](/source/Greencastle%2C_Indiana), [Kokomo](/source/Kokomo%2C_Indiana), [Lafayette](/source/Lafayette%2C_Indiana), [Marion](/source/Marion%2C_Indiana), [Muncie](/source/Muncie%2C_Indiana), [New Castle](/source/New_Castle%2C_Indiana), [Richmond](/source/Richmond%2C_Indiana), and [West Lafayette](/source/West_Lafayette%2C_Indiana). The area code was created in 1997 in a split of area code 317. ## History In 1947, [American Telephone and Telegraph](/source/American_Telephone_and_Telegraph) (AT&T) published the [first configuration of proposed numbering plan areas](/source/Original_North_American_area_codes) (NPAs) for a new nationwide numbering and toll call routing system. Indiana was divided to receive two area codes. [Area code 317](/source/Area_code_317) served the northern two-thirds of Indiana, while [area code 812](/source/Area_code_812) served the southern third. In the first change of the original plan in 1948, 317 was cut back to central Indiana, while the northern third of Indiana, including [Gary](/source/Gary%2C_Indiana), [Hammond](/source/Hammond%2C_Indiana), [East Chicago](/source/East_Chicago%2C_Indiana), [South Bend](/source/South_Bend%2C_Indiana), [Elkhart](/source/Elkhart%2C_Indiana) and [Fort Wayne](/source/Fort_Wayne), received area code 219.[1] Prior to 1996, numbering plan area 317 consisted of all of Central Indiana. Eventually, population growth and increased demand for telecommunication services required an [area code split](/source/Split_plan) to provide more central office prefixes for the region. Beginning on February 1, 1997, with mandatory [10-digit dialing](/source/10-digit_dialing) effective June 28, the greater Indianapolis area retained area code 317 and the remainder of Central Indiana received the new area code 765.[2] The creation of 765 came amid some fanfare, as it was Indiana's first new area code in 49 years. ## Service area **Entire counties** - [Blackford County](/source/Blackford_County%2C_Indiana) - [Clinton County](/source/Clinton_County%2C_Indiana) - [Delaware County](/source/Delaware_County%2C_Indiana) - [Fayette County](/source/Fayette_County%2C_Indiana) - [Fountain County](/source/Fountain_County%2C_Indiana) - [Grant County](/source/Grant_County%2C_Indiana) - [Henry County](/source/Henry_County%2C_Indiana) - [Howard County](/source/Howard_County%2C_Indiana) - [Montgomery County](/source/Montgomery_County%2C_Indiana) - [Parke County](/source/Parke_County%2C_Indiana) - [Putnam County](/source/Putnam_County%2C_Indiana) - [Randolph County](/source/Randolph_County%2C_Indiana) - [Rush County](/source/Rush_County%2C_Indiana) - [Tippecanoe County](/source/Tippecanoe_County%2C_Indiana) - [Tipton County](/source/Tipton_County%2C_Indiana) - [Warren County](/source/Warren_County%2C_Indiana) - [Wayne County](/source/Wayne_County%2C_Indiana) - [Union County](/source/Union_County%2C_Indiana) - [Vermillion County](/source/Vermillion_County%2C_Indiana) **Partial counties** - [Benton County](/source/Benton_County%2C_Indiana) - [Boone County](/source/Boone_County%2C_Indiana) - [Carroll County](/source/Carroll_County%2C_Indiana) - [Clay County](/source/Clay_County%2C_Indiana) - [Decatur County](/source/Decatur_County%2C_Indiana) - [Franklin County](/source/Franklin_County%2C_Indiana) - [Hancock County](/source/Hancock_County%2C_Indiana) - [Hamilton County](/source/Hamilton_County%2C_Indiana) - [Hendricks County](/source/Hendricks_County%2C_Indiana) - [Jay County](/source/Jay_County%2C_Indiana) - [Madison County](/source/Madison_County%2C_Indiana) - [Miami County](/source/Miami_County%2C_Indiana) - [Morgan County](/source/Morgan_County%2C_Indiana) - [Shelby County](/source/Shelby_County%2C_Indiana) - [Wabash County](/source/Wabash_County%2C_Indiana) - [Wells County](/source/Wells_County%2C_Indiana) - [White County](/source/White_County%2C_Indiana) - [Vigo County](/source/Vigo_County%2C_Indiana) ## See also - [List of Indiana area codes](/source/List_of_Indiana_area_codes) - [List of North American Numbering Plan area codes](/source/List_of_North_American_Numbering_Plan_area_codes) ## References 1. **[^](#cite_ref-1)** [Telecom Indiana, *Telecom Information for Indiana, Chicago, and Beyond*](http://telecomindiana.com/indiana1947.html) 1. **[^](#cite_ref-2)** [http://www.sbc.com/gen/general?pid=1718&phase=check](http://www.sbc.com/gen/general?pid=1718&phase=check) SBC information.
