VERNAL prefixes in area code 435

NANPA records 8 assigned NXX blocks to rate center VERNAL 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. 5 holders hold those blocks, the largest being T-MOBILE USA, INC. (3), UBTA-UBET COMMUNICATIONS, INC. DBA STRATA NETWORKS (2), UNION TELEPHONE COMPANY (1). The earliest assignment on record here is 2004-04-29 and the most recent 2011-07-06. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
