CREVECOEUR prefixes in area code 314

NANPA records 51 assigned NXX blocks to rate center CREVECOEUR in area code 314, 6.5% 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. 13 holders hold those blocks, the largest being SOUTHWESTERN BELL (19), T-MOBILE USA, INC. (6), ONVOY, LLC - MO (5). The earliest assignment on record here is 2013-03-21 and the most recent 2022-08-08. 40 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.
