TAOS prefixes in area code 575

NANPA records 14 assigned NXX blocks to rate center TAOS in area code 575, 2.7% 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. 8 holders hold those blocks, the largest being QWEST CORPORATION (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NM (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2002-05-02 and the most recent 2024-01-23. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 573 – overlay codes cover the same geography, so a rate center is served by all of them.
