BAR MILLS prefixes in area code 207

NANPA records 3 assigned NXX blocks to rate center BAR MILLS in area code 207, 0.4% 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. 2 holders hold those blocks, the largest being SACO RIVER TELEPHONE LLC (2), BELL ATLANTIC MOBILE, INC (1). The earliest assignment on record here is 2008-11-26 and the most recent 2008-11-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
