SALEM prefixes in area code 603

NANPA records 20 assigned NXX blocks to rate center SALEM in area code 603, 2.7% of the 752 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. 9 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (7), PAETEC ITEL, LLC (5), BELL ATLANTIC MOBILE, INC (2). The earliest assignment on record here is 2001-10-17 and the most recent 2019-12-09. 14 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.
