WASHINGTON prefixes in area code 908

NANPA records 13 assigned NXX blocks to rate center WASHINGTON in area code 908, 1.8% 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. 8 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - NJ (3), NEW CINGULAR WIRELESS PCS, LLC - DC (3), VERIZON NEW JERSEY, INC. (2). The earliest assignment on record here is 2001-01-26 and the most recent 2002-06-04. 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 207, 252, 309, 319 – overlay codes cover the same geography, so a rate center is served by all of them.
