MEHLVILLE prefixes in area code 314

NANPA records 24 assigned NXX blocks to rate center MEHLVILLE in area code 314, 3.1% 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. 8 holders hold those blocks, the largest being ONVOY, LLC - MO (8), SOUTHWESTERN BELL (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MO (4). The earliest assignment on record here is 2002-11-27 and the most recent 2022-08-08. 20 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.
