LOWELL prefixes in area code 351

NANPA records 5 assigned NXX blocks to rate center LOWELL in area code 351, 5.5% of the 91 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (2), COMMIO, LLC (1), OMNIPOINT MIAMI E LICENSE, LLC (1). The earliest assignment on record here is 2017-03-13 and the most recent 2023-02-21. 5 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 219, 458, 541, 616 – overlay codes cover the same geography, so a rate center is served by all of them.
