ALLENTOWN prefixes in area code 609

NANPA records 29 assigned NXX blocks to rate center ALLENTOWN 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. 10 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (12), OMNIPOINT COMMUNICATIONS ENTERPRISES, LP (4), ONVOY, LLC - NJ (3). The earliest assignment on record here is 2001-05-03 and the most recent 2024-06-04. 26 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 484, 610, 640, 835 – overlay codes cover the same geography, so a rate center is served by all of them.
