SALISBURY prefixes in area code 410

NANPA records 24 assigned NXX blocks to rate center SALISBURY in area code 410, 3.1% 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. (11), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (4), REDI-CALL COMMUNICATIONS CO. (2). The earliest assignment on record here is 2001-04-18 and the most recent 2019-06-04. 7 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, 603, 660, 667 – overlay codes cover the same geography, so a rate center is served by all of them.
