MENTOR prefixes in area code 440
NANPA records 14 assigned NXX blocks to rate center MENTOR in area code 440, 1.8% of the 757 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. 5 holders hold those blocks, the largest being OHIO BELL TEL CO (6), LEVEL 3 COMMUNICATIONS, LLC - OH (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - OH (2). The earliest assignment on record here is 2021-05-10 and the most recent 2021-05-10. 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 code 218 – overlay codes cover the same geography, so a rate center is served by all of them.
