GLOUCESTER prefixes in area code 978

NANPA records 13 assigned NXX blocks to rate center GLOUCESTER in area code 978, 1.7% 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. 8 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (4), LEVEL 3 COMMUNICATIONS, LLC - MA (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2002-02-13 and the most recent 2002-02-13. 10 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 351, 508, 804, 856 – overlay codes cover the same geography, so a rate center is served by all of them.
