TRENTON prefixes in area code 513

NANPA records 4 assigned NXX blocks to rate center TRENTON in area code 513, 0.5% 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. 4 holders hold those blocks, the largest being CINCINNATI BELL EXTENDED TERRITORIES LLC - OH (1), TWC IP ENABLED SERVICES, LLC (1), BANDWIDTH.COM CLEC, LLC - OH (1). The earliest assignment on record here is 2007-02-16 and the most recent 2018-08-02. 4 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 252, 270, 283, 308 – overlay codes cover the same geography, so a rate center is served by all of them.
