KINGSVILLE prefixes in area code 361

NANPA records 18 assigned NXX blocks to rate center KINGSVILLE in area code 361, 3.3% of the 538 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (5), STPCS JOINT VENTURE, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2001-07-10 and the most recent 2024-04-25. 14 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 440, 816 – overlay codes cover the same geography, so a rate center is served by all of them.
