SALEM prefixes in area code 618

NANPA records 4 assigned NXX blocks to rate center SALEM in area code 618, 0.5% 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. 3 holders hold those blocks, the largest being WABASH INDEPENDENT NETWORKS, INC DBA WABASH COMM (2), LEVEL 3 COMMUNICATIONS, LLC - IL (1), ILLINOIS BELL TEL CO (1). The earliest assignment on record here is 2008-04-16 and the most recent 2017-09-19. 3 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.
