NORTHEATON prefixes in area code 440

NANPA records 3 assigned NXX blocks to rate center NORTHEATON in area code 440, 0.4% of the 757 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 LEVEL 3 COMMUNICATIONS, LLC - OH (1), SIGECOM, LLC DBA WOW INTERNET CABLE AND PHONE (1), FRONTIER NORTH, INC. - OH (1). The earliest assignment on record here is 2002-09-16 and the most recent 2002-09-16. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
