CHINLE prefixes in area code 928

NANPA records 6 assigned NXX blocks to rate center CHINLE 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 NEW CINGULAR WIRELESS PCS, LLC (2), NAVAJO COMM CO INC - AZ DBA FRONTIER NAVAJO COM (2), SMITH BAGLEY INC. DBA CELLULAR ONE OF NE ARIZONA (1). The earliest assignment on record here is 2006-03-28 and the most recent 2020-05-11. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
