HARQUHLVLY prefixes in area code 928

NANPA records 3 assigned NXX blocks to rate center HARQUHLVLY in area code 928, 0.5% 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. 3 holders hold those blocks, the largest being ARIZONA TEL. CO. (1), TON80 COMMUNICATIONS, LLC (1), ONVOY, LLC - AZ (1). The earliest assignment on record here is 2020-06-02 and the most recent 2022-02-10. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
