KNOXVILLE prefixes in area code 641
NANPA records 8 assigned NXX blocks to rate center KNOXVILLE in area code 641, 1.4% of the 584 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being UNITED STATES CELLULAR - IA (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2), WINDSTREAM IOWA COMMUNICATIONS, INC. (2). 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 309, 582, 660, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
