WASHINGTON prefixes in area code 812

NANPA records 8 assigned NXX blocks to rate center WASHINGTON in area code 812, 1.0% of the 785 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. 6 holders hold those blocks, the largest being INDIANA BELL TEL CO INC (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (1). The earliest assignment on record here is 2001-09-13 and the most recent 2003-06-02. 6 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.
