EASTON prefixes in area code 443

NANPA records 9 assigned NXX blocks to rate center EASTON in area code 443, 1.1% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (3), OMNIPOINT COMMUNICATIONS CAP OPERATIONS, LLC (1), CORE COMMUNICATIONS, INC.- MD (1). The earliest assignment on record here is 2002-02-22 and the most recent 2004-01-20. 8 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, 309, 410, 484 – overlay codes cover the same geography, so a rate center is served by all of them.
