SO DEERFLD prefixes in area code 413

NANPA records 8 assigned NXX blocks to rate center SO DEERFLD in area code 413, 1.3% of the 605 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (3), VERIZON NEW ENGLAND INC. (2), TC SYSTEMS, INC. (1). The earliest assignment on record here is 2001-08-24 and the most recent 2009-05-15. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
