MONMTH JCT prefixes in area code 732

NANPA records 15 assigned NXX blocks to rate center MONMTH JCT in area code 732, 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. 8 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (4), LEVEL 3 COMMUNICATIONS, LLC - NJ (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2001-01-08 and the most recent 2024-02-23. 12 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 848 – overlay codes cover the same geography, so a rate center is served by all of them.
