KAMAS prefixes in area code 435

NANPA records 8 assigned NXX blocks to rate center KAMAS in area code 435, 1.6% of the 501 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - UT (6), TON80 COMMUNICATIONS, LLC (1), ALL WEST COMMUNICATIONS - UT (1). The earliest assignment on record here is 2020-05-12 and the most recent 2022-01-27. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
