About area code 641
Area code 641 is one of the North American Numbering Plan (NANP) codes serving Iowa. In the NANP a full number looks like +1 (641) NXX-XXXX: the +1 is the country code for the US and Canada, 641 is the area code, and the remaining seven digits identify the specific line. A call is charged by your own carrier's plan, not by the area code itself.
