TRENTON prefixes in area code 640

NANPA records 7 assigned NXX blocks to rate center TRENTON in area code 640, 5.2% of the 134 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. 7 holders hold those blocks, the largest being IP HORIZON LLC (1), ONVOY, LLC - NJ (1), NUSO, LLC (1). The earliest assignment on record here is 2021-03-02 and the most recent 2026-07-02. 7 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.
