DONNA prefixes in area code 956
NANPA records 10 assigned NXX blocks to rate center DONNA in area code 956, 1.4% 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. 6 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - TX (4), SOUTHWESTERN BELL (2), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2010-09-17 and the most recent 2024-12-05. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
