NEWPORT prefixes in area code 401

NANPA records 26 assigned NXX blocks to rate center NEWPORT in area code 401, 4.5% 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. 8 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (11), PAETEC ITEL, LLC (4), LEVEL 3 COMMUNICATIONS, LLC - RI (3). 18 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 207, 220, 223, 252 – overlay codes cover the same geography, so a rate center is served by all of them.
