BLOCK IS prefixes in area code 401
NANPA records 4 assigned NXX blocks to rate center BLOCK IS in area code 401, 0.7% of the 581 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 ONVOY, LLC - RI (2), VERIZON NEW ENGLAND INC. (1), LEVEL 3 COMMUNICATIONS, LLC - RI (1). The earliest assignment on record here is 2001-04-19 and the most recent 2017-09-27. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
