BEAVER prefixes in area code 435

NANPA records 7 assigned NXX blocks to rate center BEAVER in area code 435, 1.4% 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - UT (3), BANDWIDTH.COM CLEC, LLC - UT (1), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2001-10-23 and the most recent 2002-12-30. 7 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 codes 503, 580, 740, 907 – overlay codes cover the same geography, so a rate center is served by all of them.
