SPRINGLAKE prefixes in area code 501

NANPA records 7 assigned NXX blocks to rate center SPRINGLAKE in area code 501, 1.1% of the 631 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 (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2), WINDSTREAM COMMUNICATIONS, INC. - AR (1). The earliest assignment on record here is 2019-02-12 and the most recent 2025-04-16. 7 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 534, 715, 732, 806 – overlay codes cover the same geography, so a rate center is served by all of them.
