RIO HONDO prefixes in area code 956
NANPA records 4 assigned NXX blocks to rate center RIO HONDO in area code 956, 0.5% of the 735 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 AT&T ENTERPRISES, LLC (1), AT&T - LOCAL (1), ONVOY, LLC - TX (1). The earliest assignment on record here is 2021-04-16 and the most recent 2024-05-15. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
