TULAROSA prefixes in area code 575

NANPA records 4 assigned NXX blocks to rate center TULAROSA in area code 575, 0.8% of the 521 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 BANDWIDTH.COM CLEC, LLC - NM (2), TULAROSA BASIN TELEPHONE CO., INC. (1), ONVOY, LLC - NM (1). The earliest assignment on record here is 2014-11-13 and the most recent 2022-03-23. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
