Fax Iowa Department of Transportation — Send Documents Securely
Before you fax Iowa Department of Transportation about a transportation permit request, it is worth knowing how to keep the transmission secure — this page walks through it.

This guide covers the secure way to send the documents plus how to reach the correct office.
Does Iowa Department of Transportation accept a fax?
