BENAVIDES prefixes in area code 361

NANPA records 4 assigned NXX blocks to rate center BENAVIDES in area code 361, 0.7% of the 538 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. 4 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), SOUTHWESTERN BELL (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2017-09-18 and the most recent 2024-04-22. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
