SALEM prefixes in area code 978

NANPA records 25 assigned NXX blocks to rate center SALEM in area code 978, 3.2% of the 773 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 NEW ENGLAND INC. (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (6), LEVEL 3 COMMUNICATIONS, LLC - MA (5). The earliest assignment on record here is 2001-02-20 and the most recent 2001-10-30. 22 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.
