PIMA prefixes in area code 928
NANPA records 10 assigned NXX blocks to rate center PIMA in area code 928, 1.6% 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (3), BANDWIDTH.COM CLEC, LLC - AZ (2), ONVOY, LLC - AZ (2). The earliest assignment on record here is 2010-09-03 and the most recent 2026-10-26. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
