ROSSBURG prefixes in area code 937

NANPA records 3 assigned NXX blocks to rate center ROSSBURG in area code 937, 0.4% of the 781 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. (1), LEVEL 3 COMMUNICATIONS, LLC - OH (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2005-02-08 and the most recent 2007-07-04. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
