CANFIELD prefixes in area code 330

NANPA records 4 assigned NXX blocks to rate center CANFIELD in area code 330, 0.5% 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 OHIO BELL TEL CO (2), PAETEC ITEL, LLC (1), TELEPORT COMMUNICATIONS AMERICA, LLC - OH (1). The earliest assignment on record here is 2007-08-01 and the most recent 2007-08-01. 3 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 code 234 – overlay codes cover the same geography, so a rate center is served by all of them.
