LKHAVASUCY prefixes in area code 928

NANPA records 19 assigned NXX blocks to rate center LKHAVASUCY in area code 928, 3.0% 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. 8 holders hold those blocks, the largest being CITIZENS UTILITIES RURAL DBA FRONTIER UT RURAL (5), CSC VOICE, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (3). The earliest assignment on record here is 2001-03-19 and the most recent 2024-04-04. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
