MORROW prefixes in area code 513

NANPA records 3 assigned NXX blocks to rate center MORROW in area code 513, 0.4% 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. 3 holders hold those blocks, the largest being TWC IP ENABLED SERVICES, LLC (1), ONVOY, LLC - OH (1), BRIGHTSPEED OF NORTHWEST OHIO, INC. (1). The earliest assignment on record here is 2013-06-24 and the most recent 2018-10-23. 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 codes 283, 479 – overlay codes cover the same geography, so a rate center is served by all of them.
