PENNINGTON prefixes in area code 609

NANPA records 12 assigned NXX blocks to rate center PENNINGTON in area code 609, 1.5% 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. (3), TELEPORT COMMUNICATIONS AMERICA, LLC - NJ (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-01-15 and the most recent 2024-02-12. 10 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 205, 659, 936 – overlay codes cover the same geography, so a rate center is served by all of them.
