HOLBROOK prefixes in area code 928
NANPA records 5 assigned NXX blocks to rate center HOLBROOK in area code 928, 0.8% 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 (2), LEVEL 3 COMMUNICATIONS, LLC - AZ (1), SMITH BAGLEY INC. DBA CELLULAR ONE OF NE ARIZONA (1). The earliest assignment on record here is 2002-12-31 and the most recent 2006-12-27. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 208, 308, 986 – overlay codes cover the same geography, so a rate center is served by all of them.
