HIGHTSTOWN prefixes in area code 609

NANPA records 15 assigned NXX blocks to rate center HIGHTSTOWN in area code 609, 1.9% of the 780 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 VERIZON NEW JERSEY, INC. (6), LEVEL 3 COMMUNICATIONS, LLC - NJ (2), CSC VOICE, LLC (2). The earliest assignment on record here is 2001-01-15 and the most recent 2024-01-30. 11 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 640 – overlay codes cover the same geography, so a rate center is served by all of them.
