ANNAPOLIS prefixes in area code 410

NANPA records 36 assigned NXX blocks to rate center ANNAPOLIS in area code 410, 4.6% 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. 8 holders hold those blocks, the largest being VERIZON MARYLAND, INC. (17), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (7), NEW CINGULAR WIRELESS PCS, LLC - DC (5). The earliest assignment on record here is 2002-01-22 and the most recent 2012-01-27. 16 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 443, 573, 618, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
