KINGSTON prefixes in area code 580

NANPA records 5 assigned NXX blocks to rate center KINGSTON in area code 580, 0.7% 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. 5 holders hold those blocks, the largest being SOUTHWESTERN BELL (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2003-02-20 and the most recent 2025-03-20. 5 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 272, 319, 329, 339 – overlay codes cover the same geography, so a rate center is served by all of them.
