ORD prefixes in area code 308

NANPA records 3 assigned NXX blocks to rate center ORD in area code 308, 0.6% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), CITIZENS TELECOM OF NE LLC DBA FRONTIER COM OF NE (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NE (1). The earliest assignment on record here is 2020-10-15 and the most recent 2020-10-15. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
