KAYSVILLE prefixes in area code 801

NANPA records 44 assigned NXX blocks to rate center KAYSVILLE in area code 801, 5.6% of the 783 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. 9 holders hold those blocks, the largest being QWEST CORPORATION (12), NEW CINGULAR WIRELESS PCS, LLC (8), T-MOBILE USA, INC. (8). The earliest assignment on record here is 2001-03-16 and the most recent 2010-12-23. 29 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 385 – overlay codes cover the same geography, so a rate center is served by all of them.
