ADA prefixes in area code 580
NANPA records 22 assigned NXX blocks to rate center ADA in area code 580, 3.0% of the 741 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 SOUTHWESTERN BELL (7), T-MOBILE USA, INC. (4), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2001-06-19 and the most recent 2026-07-30. 18 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 218, 419, 567, 616 – overlay codes cover the same geography, so a rate center is served by all of them.
