LYNNFIELD prefixes in area code 781

NANPA records 9 assigned NXX blocks to rate center LYNNFIELD in area code 781, 1.2% of the 769 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. 7 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2), TC SYSTEMS, INC. (1). The earliest assignment on record here is 2001-02-23 and the most recent 2013-11-03. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
