Iowa Antique Vehicle Registration Guide for Classic Cars

If you own a car that’s at least 25 years old, Iowa’s antique vehicle registration can save you money and hassle. The Iowa antique vehicle registration for cars 25 years and older offers reduced fees and special plates, but the rules are specific about what qualifies and how you can use the vehicle.

As of 2026, Iowa requires vehicles to be 25 years or older to qualify, and they must be used primarily for exhibitions, parades, or club events. The process is straightforward if you know the steps, but missing a detail can delay approval.

Fees are lower than standard registration.

How Iowa Defines an Antique Vehicle

Iowa classifies a vehicle as antique if it’s at least 25 years old. The age is based on the model year, not the manufacture date. The vehicle must also be in original or restored condition.

Modified vehicles may not qualify unless the changes are period-correct. Daily use is not allowed under antique registration. For official definitions, check the Iowa Department of Transportation.

Antique vs. Classic vs. Regular Registration in Iowa

Antique registration is for vehicles 25+ years old with limited use. Classic registration may apply to newer collectible cars, but Iowa’s rules focus on age. Regular registration is for everyday vehicles with no restrictions.

Antique plates cost less but come with usage limits. Regular plates allow unlimited driving but at a higher cost.
