CLARKSVL prefixes in area code 479

NANPA records 9 assigned NXX blocks to rate center CLARKSVL in area code 479, 1.6% of the 569 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 BRIGHTSPEED OF NORTHWEST ARKANSAS, LLC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (2), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-03-08 and the most recent 2022-11-18. 7 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 217, 319, 430, 434 – overlay codes cover the same geography, so a rate center is served by all of them.
