WENTZVILLE prefixes in area code 636

NANPA records 14 assigned NXX blocks to rate center WENTZVILLE 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (4), BRIGHTSPEED OF MISSOURI, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2004-12-13 and the most recent 2021-09-08. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
