SHELBUNFLS prefixes in area code 413

NANPA records 4 assigned NXX blocks to rate center SHELBUNFLS in area code 413, 0.7% 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 BANDWIDTH.COM CLEC, LLC - MA (1), VERIZON NEW ENGLAND INC. (1), ONVOY, LLC - MA (1). The earliest assignment on record here is 2001-07-27 and the most recent 2021-03-25. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
