NO KINGSTN prefixes in area code 401

NANPA records 11 assigned NXX blocks to rate center NO KINGSTN in area code 401, 1.9% 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. 7 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (4), LEVEL 3 COMMUNICATIONS, LLC - RI (2), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1). 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
