EL DORADO prefixes in area code 870
NANPA records 24 assigned NXX blocks to rate center EL DORADO in area code 870, 3.1% of the 785 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 (6), NEW CINGULAR WIRELESS PCS, LLC - IL (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (4). The earliest assignment on record here is 2003-02-04 and the most recent 2023-03-24. 17 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 316 – overlay codes cover the same geography, so a rate center is served by all of them.
