CORTLAND prefixes in area code 330

NANPA records 7 assigned NXX blocks to rate center CORTLAND in area code 330, 0.9% of the 787 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 BRIGHTSPEED OF NORTHWEST OHIO, INC. (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (2). The earliest assignment on record here is 2004-03-16 and the most recent 2015-04-07. 5 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 234, 402, 607 – overlay codes cover the same geography, so a rate center is served by all of them.
