RATON prefixes in area code 575

NANPA records 9 assigned NXX blocks to rate center RATON in area code 575, 1.7% 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. 6 holders hold those blocks, the largest being ONVOY, LLC - NM (2), BANDWIDTH.COM CLEC, LLC - NM (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2003-06-24 and the most recent 2018-03-14. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
