KITTERY prefixes in area code 207

NANPA records 8 assigned NXX blocks to rate center KITTERY in area code 207, 1.1% 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 (4), COMCAST IP PHONE, LLC (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2008-04-02 and the most recent 2019-04-12. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
