SANDISFLD prefixes in area code 413

NANPA records 3 assigned NXX blocks to rate center SANDISFLD in area code 413, 0.5% 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. 3 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (1), ONVOY, LLC - MA (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2018-06-25 and the most recent 2021-11-22. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
