SOUTHWICK prefixes in area code 413
NANPA records 6 assigned NXX blocks to rate center SOUTHWICK in area code 413, 1.0% 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. 4 holders hold those blocks, the largest being PAETEC ITEL, LLC (3), TC SYSTEMS, INC. (1), ONVOY, LLC - MA (1). The earliest assignment on record here is 2019-03-26 and the most recent 2021-11-09. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
