MAUMEE prefixes in area code 419

NANPA records 7 assigned NXX blocks to rate center MAUMEE in area code 419, 0.9% of the 783 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 OHIO BELL TEL CO (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - OH (1), ONVOY, LLC - OH (1). 4 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 567 – overlay codes cover the same geography, so a rate center is served by all of them.
