SAPPINGTON prefixes in area code 314

NANPA records 25 assigned NXX blocks to rate center SAPPINGTON in area code 314, 3.2% of the 783 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 (9), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MO (4), BANDWIDTH.COM CLEC, LLC - MO (3). The earliest assignment on record here is 2001-12-19 and the most recent 2022-01-11. 19 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 code 557 – overlay codes cover the same geography, so a rate center is served by all of them.
