WESTERVL prefixes in area code 380

NANPA records 9 assigned NXX blocks to rate center WESTERVL in area code 380, 6.5% of the 138 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. 7 holders hold those blocks, the largest being ONVOY, LLC - OH (3), VONAGE AMERICA LLC (1), BANDWIDTH.COM CLEC, LLC - OH (1). The earliest assignment on record here is 2016-04-07 and the most recent 2025-04-15. 9 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 614 – overlay codes cover the same geography, so a rate center is served by all of them.
