ABIQUIU prefixes in area code 505

NANPA records 5 assigned NXX blocks to rate center ABIQUIU in area code 505, 0.7% of the 685 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 (3), FRACTEL, LLC (1), VALOR TELECOM TX,LP-NM #2 DBA WINDSTREAM COMM SW (1). The earliest assignment on record here is 2005-03-09 and the most recent 2023-05-15. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
