NANPA records 6 assigned NXX blocks to rate center GILA BEND in area code 928, 0.9% of the 637 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. 6 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - AZ (1), LEVEL 3 COMMUNICATIONS, LLC - AZ (1), LEVEL 3 TELECOM OF ARIZONA, LLC - AZ (1). The earliest assignment on record here is 2015-06-29 and the most recent 2022-01-13. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
