TWINSBURG prefixes in area code 234

NANPA records 6 assigned NXX blocks to rate center TWINSBURG in area code 234, 1.5% of the 398 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 WINDSTREAM WESTERN RESERVE, INC. (1), T-MOBILE USA, INC. (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - OH (1). The earliest assignment on record here is 2012-06-05 and the most recent 2026-07-07. 6 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 330 – overlay codes cover the same geography, so a rate center is served by all of them.
