CLOVIS prefixes in area code 575

NANPA records 22 assigned NXX blocks to rate center CLOVIS in area code 575, 4.2% 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. 10 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (5), QWEST CORPORATION (5), T-MOBILE USA, INC. (4). The earliest assignment on record here is 2001-12-18 and the most recent 2024-03-07. 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 codes 357, 559 – overlay codes cover the same geography, so a rate center is served by all of them.
