W NEWBURY prefixes in area code 978

NANPA records 7 assigned NXX blocks to rate center W NEWBURY in area code 978, 0.9% of the 773 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. 5 holders hold those blocks, the largest being PAETEC ITEL, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - MA (2), VERIZON NEW ENGLAND INC. (1). 7 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 802 – overlay codes cover the same geography, so a rate center is served by all of them.
