SEVEN MILE prefixes in area code 513

NANPA records 8 assigned NXX blocks to rate center SEVEN MILE 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. 5 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), LEVEL 3 COMMUNICATIONS, LLC - OH (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2004-06-23 and the most recent 2022-12-08. 8 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 283 – overlay codes cover the same geography, so a rate center is served by all of them.
