About the 641 area code
Since 2000, area code 641 has covered a swath of Iowa that includes Mason City, Ames, Marshalltown, Ottumwa, and Grinnell, every one of them on Central time.
The code owes its existence to a split, its territory having been drawn out of area code 515. It carries no overlay and has produced no offspring codes, and its boundaries are the same today as they were at the start.
Dialing note: 641 was carved out of the 515 territory and went into service in 2000.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 10/08/2026.
