Where to renew and what you'll need
In Iowa, you renew your driver's license at your local county treasurer's office, not at the DMV — Iowa doesn't have a separate DMV. You can also renew by mail or online, depending on your situation. The method you choose depends on whether your license is still valid, how much time you have, and whether you need to change any information on your license.
Before you go anywhere, gather these documents: your current driver's license, proof of your Social Security number (your Social Security card, W-2, or 1099 form), and proof of your current Iowa address (a utility bill, lease, or bank statement dated within the last 60 days). If you've changed your name since your last license, bring a marriage certificate, divorce decree, or court order showing the change.
Your license is valid for four years from your birthday. You can renew it up to one year before it expires, so you don't have to wait until the last minute. Renewing early gives you time to handle any problems that come up.
Key Takeaways
- You renew at your county treasurer's office in person, or by mail or online if your license is still valid and you haven't changed your address or name.
- Bring your current license, proof of your Social Security number, and proof of your current address — all documents must be originals or certified copies.
- The renewal fee is $20 for a four-year license, and you can renew up to one year before your birthday.
- Online renewal takes a few minutes and your new license arrives by mail in about one to two weeks.
- If your license is expired or you've moved out of state since you got it, you must renew in person at the treasurer's office.
Renewing online or by mail
Online renewal is the fastest option if you're may be able to access. You can renew online at iowadot.gov if your current license is still valid, you haven't changed your name or address, and you're renewing a standard driver's license (not a commercial license). The process takes about five minutes. You'll enter your license number, date of birth, and the last four digits of your Social Security number. You'll pay the $20 renewal fee with a credit or debit card, and your new license will be mailed to the address on file.
Mail renewal works the same way: you send in your current license, a completed renewal form (available at iowadot.gov), and a check or money order for $20. Mail it to the address listed on the form. Processing takes about two to three weeks once the office receives it, plus mail time on both ends.
Both online and mail renewal are only for people whose licenses are current and whose information hasn't changed. If your license is expired, you've moved, or you need to update your name, you must go in person to your county treasurer's office.
Renewing in person at the treasurer's office
Walk into your county treasurer's office with your documents and tell them you're renewing your driver's license. You'll fill out a form (they have them at the desk), hand over your documents, and pay $20. The whole visit usually takes 15 to 30 minutes, depending on how busy the office is. Your new license is printed on the spot, and you leave with it the same day.
In-person renewal is required if your license is expired, if you've changed your name or address, or if you need to correct any information on your license. It's also the only option if you're renewing a commercial driver's license or if you need to add or remove endorsements (like a motorcycle endorsement).
Find your county treasurer's office by searching "[your county name] Iowa treasurer" online, or go to the county government website. Hours vary by county, but most are open Monday through Friday during business hours. Some larger offices stay open one evening a week or offer Saturday hours — call ahead to check.
What happens if your license is expired
If your license has been expired for more than one year, Iowa treats it as a new license process rather than a renewal. You'll need to take a written test and an eye exam at the treasurer's office, in addition to providing all your documents. The process takes longer and costs more ($20 for the license plus test fees). If your license expired less than one year ago, you can still renew without retesting — go in person and bring all your documents.
Driving on an expired license is illegal in Iowa, even if you're on your way to renew it. If you're pulled over, you can be ticketed. If your license expired recently and you need to drive before you can renew, contact your county treasurer's office to ask about a temporary permit or extension.
Changing your address or name during renewal
If you've moved to a new address in Iowa, you must update your license in person at the treasurer's office. Bring your current license and proof of your new address (a utility bill, lease, or bank statement dated within the last 60 days). The fee is still $20, and you'll get your new license the same day with your updated address.
If you've changed your name since your last license — through marriage, divorce, or court order — you also must renew in person. Bring your current license, proof of the name change (marriage certificate, divorce decree, or court order), and proof of your address. Again, the fee is $20 and you leave with your new license.
You cannot update your address or name online or by mail. These changes require an in-person visit so the office can verify your documents.
Commercial driver's licenses and endorsements
If you hold a commercial driver's license (CDL), you cannot renew online or by mail. You must go in person to your county treasurer's office. Bring your current CDL, proof of your Social Security number, and proof of your address. You may need to take a written test depending on what type of CDL you hold and whether your endorsements are changing. The fee is $20 for a four-year renewal.
If you want to add or remove an endorsement (such as a motorcycle endorsement, hazmat endorsement, or passenger endorsement), you must renew in person. Some endorsements require an additional written test or skills test. Ask your county treasurer's office which tests you'll need before you go in.
Timeline and what to expect
If you renew in person, you walk out with your new license the same day. If you renew online, your license arrives by mail in about one to two weeks. If you renew by mail, allow two to three weeks for processing plus mail time — so plan for three to four weeks total.
Your new license is valid for four years from your birthday. You can start using it as soon as you receive it. If you renew before your birthday, your new expiration date will be four years from your current birthday, not four years from the renewal date.
Frequently Asked Questions
Can I renew my license if I'm out of state?
If you're temporarily out of state, you can renew online or by mail as long as your license is still valid and your information hasn't changed. If you've moved out of state permanently, you cannot renew an Iowa license — you'll need to get a license from your new state instead.
What if I lost my current license?
If you've lost your license, you cannot renew online or by mail. Go in person to your county treasurer's office with your proof of Social Security number and proof of address. You'll pay $20 for the renewal, and they'll issue a new license on the spot. Bring a police report of the loss if you have one, though it's not required.
Do I need an appointment to renew in person?
Most county treasurer's offices do not require appointments for license renewal — you can walk in during business hours. However, some larger offices in bigger counties may have moved to appointment-only service. Call your county treasurer's office ahead of time to ask whether you need an appointment.
What if my address proof is older than 60 days?
Your address proof must be dated within the last 60 days. If your utility bill or lease is older than that, bring a more recent document instead. A current bank statement, insurance bill, or government letter with your name and address will work.
Can I renew my license online if I wear glasses?
Yes. Online renewal does not include an eye exam — it assumes your vision hasn't changed since your last license. If your vision has changed significantly or you're unsure, renew in person so the office can check your vision and update your license if needed.
