MIDDLETOWN prefixes in area code 513

NANPA records 38 assigned NXX blocks to rate center MIDDLETOWN in area code 513, 4.8% 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. 12 holders hold those blocks, the largest being OHIO BELL TEL CO (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (7), T-MOBILE USA, INC. (6). The earliest assignment on record here is 2001-04-30 and the most recent 2023-06-09. 28 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 223, 227, 240, 283 – overlay codes cover the same geography, so a rate center is served by all of them.
