DENNISVL prefixes in area code 609

NANPA records 6 assigned NXX blocks to rate center DENNISVL in area code 609, 0.8% 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. 5 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - NJ (1), COMMIO, LLC (1). The earliest assignment on record here is 2001-06-20 and the most recent 2023-04-03. 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 640 – overlay codes cover the same geography, so a rate center is served by all of them.
