WOONSOCKET prefixes in area code 401

NANPA records 34 assigned NXX blocks to rate center WOONSOCKET in area code 401, 5.9% 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. 11 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (13), PAETEC ITEL, LLC (5), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (4). The earliest assignment on record here is 2001-06-04 and the most recent 2013-11-25. 24 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 code 605 – overlay codes cover the same geography, so a rate center is served by all of them.
