BIG SPRING prefixes in area code 432

NANPA records 16 assigned NXX blocks to rate center BIG SPRING in area code 432, 4.7% 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (5), NEW CINGULAR WIRELESS PCS, LLC - IL (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-03-13 and the most recent 2024-06-12. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
