Phone companies in area code 385
41 carriers hold the 494 central office codes assigned in 385. New Cingular Wireless PCS, LLC has the most, with 97 (20%). 494 of the codes (100%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself.
