HARTVILLE prefixes in area code 330

NANPA records 6 assigned NXX blocks to rate center HARTVILLE in area code 330, 0.8% 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - OH (1), T-MOBILE USA, INC. (1), ONVOY, LLC - OH (1). 4 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, 417 – overlay codes cover the same geography, so a rate center is served by all of them.
