SALEM prefixes in area code 540

NANPA records 11 assigned NXX blocks to rate center SALEM in area code 540, 1.4% of the 786 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 VIRGINIA, INC. (6), LEVEL 3 COMMUNICATIONS, LLC - VA (1), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2001-03-13 and the most recent 2021-04-30. 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, 234, 262, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
