About the 636 area code
St. Louis anchors the Missouri region assigned area code 636, which serves O'Fallon, St. Peters, Chesterfield, Wildwood, and Wentzville, with clocks set to Central time.
The code was switched on in 1999, taking over territory that had belonged to area code 314. Nothing has been layered over it and nothing further has been carved from it, so it remains a standalone code with the shape it had at launch.
