BRIGHAM CY prefixes in area code 435
NANPA records 23 assigned NXX blocks to rate center BRIGHAM CY in area code 435, 4.6% 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. 12 holders hold those blocks, the largest being T-MOBILE USA, INC. (5), QWEST CORPORATION (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - UT (3). The earliest assignment on record here is 2001-04-13 and the most recent 2025-12-03. 21 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
