HEBER prefixes in area code 928

NANPA records 4 assigned NXX blocks to rate center HEBER in area code 928, 0.6% 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (1), SMITH BAGLEY INC. DBA CELLULAR ONE OF NE ARIZONA (1), CITIZENS TELECOM CO OF WHITE MOUNTAINS INC. (1). The earliest assignment on record here is 2002-12-31 and the most recent 2022-02-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
