VALLEYPARK prefixes in area code 636
NANPA records 14 assigned NXX blocks to rate center VALLEYPARK in area code 636, 3.2% of the 435 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 (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MO (3), ONVOY, LLC - MO (2). The earliest assignment on record here is 2001-07-05 and the most recent 2001-07-05. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
