WILLISTON prefixes in area code 352

NANPA records 5 assigned NXX blocks to rate center WILLISTON in area code 352, 0.7% of the 711 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. 4 holders hold those blocks, the largest being CENTURYLINK OF FLORIDA, INC. (UNITED) (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - FL (1), METROPCS NETWORKS, LLC (1). The earliest assignment on record here is 2003-07-14 and the most recent 2020-12-28. 5 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 701, 803, 839 – overlay codes cover the same geography, so a rate center is served by all of them.
