MOUNTHOLLY prefixes in area code 609

NANPA records 29 assigned NXX blocks to rate center MOUNTHOLLY in area code 609, 3.7% 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (7), VERIZON NEW JERSEY, INC. (6), NEW CINGULAR WIRELESS PCS, LLC - DC (4). The earliest assignment on record here is 2001-02-09 and the most recent 2024-03-12. 21 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 640, 704, 802, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
