CANYON prefixes in area code 806

NANPA records 10 assigned NXX blocks to rate center CANYON in area code 806, 1.4% of the 734 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. 8 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TX (2), SOUTHWESTERN BELL (2), VEXUS (1). The earliest assignment on record here is 2001-03-21 and the most recent 2024-10-02. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
