KANAB prefixes in area code 435

NANPA records 4 assigned NXX blocks to rate center KANAB in area code 435, 0.8% 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 (2), SOUTH CENTRAL UTAH TEL. ASSN., INC. (1), NEW CINGULAR WIRELESS PCS, LLC (1). 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
