W LEBANON prefixes in area code 603

NANPA records 8 assigned NXX blocks to rate center W LEBANON in area code 603, 1.1% 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. 4 holders hold those blocks, the largest being UNITED STATES CELLULAR - NH (4), BELL ATLANTIC MOBILE, INC (2), CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (1). The earliest assignment on record here is 2001-03-22 and the most recent 2002-05-20. 8 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, 518, 765, 838 – overlay codes cover the same geography, so a rate center is served by all of them.
