ADARIO prefixes in area code 567

NANPA records 3 assigned NXX blocks to rate center ADARIO in area code 567, 0.7% of the 421 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 ARMSTRONG TELECOMMUNICATIONS, INC. - OH (1), LEVEL 3 COMMUNICATIONS, LLC - OH (1), FRACTEL, LLC (1). The earliest assignment on record here is 2011-06-23 and the most recent 2021-04-15. 2 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 419 – overlay codes cover the same geography, so a rate center is served by all of them.
