JOHN DAY prefixes in area code 541

NANPA records 4 assigned NXX blocks to rate center JOHN DAY in area code 541, 0.5% of the 783 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 CENTURYTEL OF OREGON, INC. DBA CENTURYLINK (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (1), ONVOY, LLC - OR (1). The earliest assignment on record here is 2005-06-20 and the most recent 2008-09-04. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
