Iowa Boat Registration Lettering

The state of Iowa surprisingly has a vast amount lakes to pick from which makes it a great boating destination. You don't want to find yourself without proper state identification though! When boating in Iowa follow the guide below to properly display registration information on your boat.

General information about numbers

We'll guide you through the process of creating Iowa boat numbers when you click design now. Each state has specific verbiage as to their requirements. See the Iowa specific section below. The general requirements for boat registrations numbers are as follows:

  • A minimum of 3" letter height
  • A block style font such as (impact or arial black)
  • Generally located on the forward hull portion of the boat next to the DNR tag
  • A contrasting color to base color of your boat.
  • Letters separated by a space or a dash (-)

Iowa Specific Registration Laws

Please review your state specific requirements before purchasing identification decals as they do vary from state to state. Our designer is setup to comply with the general requirements above. If you require a specific requirement not in our designer, just leave a comment at checkout and we'll adust your design (no big deal!). Iowa DNR website surprisingly lacks specific information about registration number sizing. If you want to be 100% sure you are compliant you will have to call your local DMV or DNR office. Here is the information they provide on their site. Here.
