WHITERIVER prefixes in area code 928

NANPA records 5 assigned NXX blocks to rate center WHITERIVER 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. 2 holders hold those blocks, the largest being CITIZENS TELECOM CO OF WHITE MOUNTAINS INC. (4), SMITH BAGLEY INC. DBA CELLULAR ONE OF NE ARIZONA (1). The earliest assignment on record here is 2005-12-20 and the most recent 2005-12-20. 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 605, 806 – overlay codes cover the same geography, so a rate center is served by all of them.
