SALEM prefixes in area code 812

NANPA records 8 assigned NXX blocks to rate center SALEM in area code 812, 1.0% 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 FRONTIER NORTH, INC. - IN (2), METROPCS, INC. (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2001-05-07 and the most recent 2008-12-29. 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 207, 234, 262, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
