RUMFORD prefixes in area code 207

NANPA records 5 assigned NXX blocks to rate center RUMFORD in area code 207, 0.7% of the 742 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 CONSOLIDATED COMM OF NO. NEW ENGLAND-ME (2), UNITED STATES CELLULAR - ME (1), BELL ATLANTIC MOBILE, INC (1). The earliest assignment on record here is 2012-05-23 and the most recent 2012-05-23. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
