ATMORE prefixes in area code 251

NANPA records 16 assigned NXX blocks to rate center ATMORE in area code 251, 3.0% of the 528 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. 8 holders hold those blocks, the largest being ELISKA WIRELESS VENTURES SUBSIDIARY I, LLC (4), ONVOY, LLC - AL (4), FRONTIER COMMUNICATIONS OF THE SOUTH, LLC - AL (2). The earliest assignment on record here is 2002-12-17 and the most recent 2023-04-18. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
