EASTON prefixes in area code 410

NANPA records 14 assigned NXX blocks to rate center EASTON in area code 410, 1.8% of the 783 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 VERIZON MARYLAND, INC. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (3), NEW CINGULAR WIRELESS PCS, LLC - DC (2). The earliest assignment on record here is 2002-05-20 and the most recent 2004-05-27. 9 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, 443, 484 – overlay codes cover the same geography, so a rate center is served by all of them.
