SPRINGERVL prefixes in area code 928

NANPA records 6 assigned NXX blocks to rate center SPRINGERVL 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AZ (3), TELEPORT COMMUNICATIONS AMERICA, LLC - AZ (1), CITIZENS TELECOM CO OF WHITE MOUNTAINS INC. (1). The earliest assignment on record here is 2002-12-31 and the most recent 2026-06-05. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
