ARANSSPASS prefixes in area code 361

NANPA records 7 assigned NXX blocks to rate center ARANSSPASS in area code 361, 1.3% 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. 6 holders hold those blocks, the largest being FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), ONVOY, LLC - TX (1), NUSO, LLC (1). The earliest assignment on record here is 2001-05-07 and the most recent 2022-11-08. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
