HAMMONTON prefixes in area code 609

NANPA records 9 assigned NXX blocks to rate center HAMMONTON in area code 609, 1.2% 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. (3), LEVEL 3 COMMUNICATIONS, LLC - NJ (2), OMNIPOINT COMMUNICATIONS ENTERPRISES, LP (2). The earliest assignment on record here is 2001-06-20 and the most recent 2019-08-12. 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 code 640 – overlay codes cover the same geography, so a rate center is served by all of them.
