About the 660 area code

Since 1997, Missouri communities such as Sedalia, Warrensburg, Kirksville, Marshall, and Chillicothe have drawn their numbers from area code 660. The whole code sits on Central time.

At its launch the code was separated from area code 816, which had covered the territory before it. 660 has gone unaccompanied since then, with no overlay in place and no descendant codes, and its coverage stands as first drawn.

Dialing note: 660 was carved out of the 816 territory and went into service in 1997.

Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
