LOWELL prefixes in area code 616

NANPA records 7 assigned NXX blocks to rate center LOWELL in area code 616, 1.3% of the 545 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. 3 holders hold those blocks, the largest being ONVOY, LLCV - MI (4), MICHIGAN BELL TEL CO (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (1). The earliest assignment on record here is 2010-12-23 and the most recent 2023-07-06. 6 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, 351, 458, 541 – overlay codes cover the same geography, so a rate center is served by all of them.
