Area code 308

About area code 308

NANPA lists 308 as an in-service geographic area code for Nebraska, first put into service on January 1, 1955. It is not part of an overlay, so every number in its territory starts with 308. It is in the Central and Mountain time zone. The places with the most assigned exchanges include Grand Island, Kearney, Scottsbluff, McCook, and Lexington. By population, its largest named places are Grand Island, Kearney, Scottsbluff, Lexington, and Gering.

Ten-digit and seven-digit dialing in 308

Who holds 308 exchanges

64 carriers hold the 463 central office codes assigned in 308. New Cingular Wireless PCS, LLC - Il has the most, with 57 (12%). 288 of the codes (62%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Where 308 numbers are rated

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 308 has codes in 167 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.

How full is area code 308?
