DOUGLASS prefixes in area code 316

NANPA records 4 assigned NXX blocks to rate center DOUGLASS in area code 316, 1.2% 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. 3 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), ONVOY, LLC - KS (1), CORETEL KANSAS, INC. - KS (1). The earliest assignment on record here is 2019-12-05 and the most recent 2023-06-30. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
