RATHBONE prefixes in area code 740

NANPA records 3 assigned NXX blocks to rate center RATHBONE in area code 740, 0.4% of the 786 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 FRONTIER NORTH, INC. - OH (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - OH (1), LEVEL 3 TELECOM OF OHIO, LLC - OH (1). The earliest assignment on record here is 2004-05-10 and the most recent 2008-04-15. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
