CHADRON prefixes in area code 308

NANPA records 5 assigned NXX blocks to rate center CHADRON in area code 308, 1.1% of the 465 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 - NE (2), N.E. COLORADO CELLULAR, INC. (1), QWEST CORPORATION (1). The earliest assignment on record here is 2002-05-21 and the most recent 2006-08-08. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
