URIAH prefixes in area code 251

NANPA records 3 assigned NXX blocks to rate center URIAH in area code 251, 0.6% 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. 2 holders hold those blocks, the largest being ONVOY, LLC - AL (2), FRONTIER COMMUNICATIONS OF THE SOUTH, LLC - AL (1). The earliest assignment on record here is 2021-01-06 and the most recent 2023-03-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
