EL DORADO prefixes in area code 316

NANPA records 17 assigned NXX blocks to rate center EL DORADO in area code 316, 5.0% of the 341 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 T-MOBILE USA, INC. (4), SOUTHWESTERN BELL (4), ONVOY, LLC - KS (2). The earliest assignment on record here is 2001-06-07 and the most recent 2023-07-06. 16 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 870 – overlay codes cover the same geography, so a rate center is served by all of them.
