AUSTINBURG prefixes in area code 440

NANPA records 4 assigned NXX blocks to rate center AUSTINBURG in area code 440, 0.5% 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. 3 holders hold those blocks, the largest being WINDSTREAM WESTERN RESERVE, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - OH (1), ONVOY, LLC - OH (1). The earliest assignment on record here is 2021-03-26 and the most recent 2021-03-26. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
