HARRISON prefixes in area code 513

NANPA records 8 assigned NXX blocks to rate center HARRISON in area code 513, 1.0% of the 784 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. 7 holders hold those blocks, the largest being CINCINNATI BELL (2), LEVEL 3 COMMUNICATIONS, LLC - OH (1), PAETEC ITEL, LLC (1). 7 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 207, 208, 283, 308 – overlay codes cover the same geography, so a rate center is served by all of them.
