ST PETERS prefixes in area code 636

NANPA records 15 assigned NXX blocks to rate center ST PETERS in area code 636, 3.4% 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. 10 holders hold those blocks, the largest being BRIGHTSPEED OF MISSOURI, LLC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-08-08 and the most recent 2025-01-07. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
