HAVERHILL prefixes in area code 978

NANPA records 26 assigned NXX blocks to rate center HAVERHILL in area code 978, 3.4% 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 OMNIPOINT MIAMI E LICENSE, LLC (7), VERIZON NEW ENGLAND INC. (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (5). The earliest assignment on record here is 2001-04-19 and the most recent 2023-09-15. 20 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, 641 – overlay codes cover the same geography, so a rate center is served by all of them.
