PT ARANSAS prefixes in area code 361

NANPA records 4 assigned NXX blocks to rate center PT ARANSAS 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), ONVOY, LLC - TX (1), BRIGHTSPEED OF COASTAL TEXAS, INC (1). The earliest assignment on record here is 2009-05-05 and the most recent 2014-07-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
