WILBURTON prefixes in area code 918

NANPA records 4 assigned NXX blocks to rate center WILBURTON in area code 918, 0.5% of the 782 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. 3 holders hold those blocks, the largest being UNITED STATES CELLULAR - OK (2), SOUTHWESTERN BELL (1), LEVEL 3 COMMUNICATIONS, LLC - OK (1). The earliest assignment on record here is 2002-10-08 and the most recent 2002-10-08. 4 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 code 539 – overlay codes cover the same geography, so a rate center is served by all of them.
