WESTFIELD prefixes in area code 908

NANPA records 23 assigned NXX blocks to rate center WESTFIELD in area code 908, 3.2% of the 721 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. 9 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (9), PAETEC ITEL, LLC (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3). The earliest assignment on record here is 2001-06-15 and the most recent 2001-12-21. 17 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 217, 281, 317, 336 – overlay codes cover the same geography, so a rate center is served by all of them.
