CEDAR CITY prefixes in area code 435

NANPA records 22 assigned NXX blocks to rate center CEDAR CITY in area code 435, 4.4% 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. 11 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), QWEST CORPORATION (4), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-02-07 and the most recent 2009-07-06. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
