FITCHBURG prefixes in area code 978

NANPA records 24 assigned NXX blocks to rate center FITCHBURG in area code 978, 3.1% 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. 7 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (7), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (4), PAETEC ITEL, LLC (4). The earliest assignment on record here is 2001-05-08 and the most recent 2002-08-28. 16 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, 517 – overlay codes cover the same geography, so a rate center is served by all of them.
