DIXON prefixes in area code 505

NANPA records 3 assigned NXX blocks to rate center DIXON in area code 505, 0.4% 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 ONVOY, LLC - NM (1), TON80 COMMUNICATIONS, LLC (1), VALOR TELECOM TX,LP-NM #2 DBA WINDSTREAM COMM SW (1). The earliest assignment on record here is 2018-05-08 and the most recent 2022-03-01. 2 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 270, 364, 369, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
