FRAZEYSBG prefixes in area code 220

NANPA records 3 assigned NXX blocks to rate center FRAZEYSBG in area code 220, 2.1% of the 142 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. 1 holder holds those blocks, the largest being ONVOY, LLC - OH (3). The earliest assignment on record here is 2016-03-17 and the most recent 2023-08-17. 3 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 740 – overlay codes cover the same geography, so a rate center is served by all of them.
