JASPER prefixes in area code 409

NANPA records 14 assigned NXX blocks to rate center JASPER in area code 409, 3.2% of the 434 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (6), NEW CINGULAR WIRELESS PCS, LLC - IL (4), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2004-10-26 and the most recent 2025-04-10. 12 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 205, 386, 417, 423 – overlay codes cover the same geography, so a rate center is served by all of them.
