PORTALES prefixes in area code 575

NANPA records 8 assigned NXX blocks to rate center PORTALES in area code 575, 1.5% 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. 6 holders hold those blocks, the largest being QWEST CORPORATION (3), YUCCA TELECOMM SYSTEMS, INC., DBA YUCCA COMM-NM (1), PEERLESS NETWORK OF NEW MEXICO, LLC - NM (1). The earliest assignment on record here is 2004-01-22 and the most recent 2019-08-28. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
