SALEM prefixes in area code 864

NANPA records 6 assigned NXX blocks to rate center SALEM in area code 864, 0.8% of the 784 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. 5 holders hold those blocks, the largest being ONVOY, LLC - SC (2), LEVEL 3 COMMUNICATIONS, LLC - SC (1), BELLSOUTH TELECOMM INC DBA SOUTHERN BELL TEL & TEL (1). The earliest assignment on record here is 2004-06-30 and the most recent 2024-11-07. 4 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.
