Services Available at the Janesville Location

The Rock County DMV handles the full range of Wisconsin motor vehicle transactions. You can renew, replace, or obtain a driver's license; renew or replace a vehicle registration; explore for or renew a vehicle title; and handle address changes on your license or registration.

The office also processes commercial driver's license (CDL) transactions, issues Wisconsin ID cards for non-drivers, and handles vehicle title transfers when you buy or sell a car. If you need to register a vehicle from out of state or resolve a title issue, the Janesville office can walk you through the Wisconsin-specific requirements.

Not all services can be completed by mail or online. License renewals and some registration renewals can be done through the Wisconsin DMV website if you meet the requirements, but title work, address changes on a license, and first-time registrations typically require an in-person visit.

What Documents to Bring to Your Appointment

Bring your current, valid photo ID — a driver's license, passport, or military ID. You will also need proof of Wisconsin residency, which can be a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days and showing your current address.

For a driver's license renewal or replacement, bring your current license and your Social Security card or a document showing your Social Security number. For vehicle registration or title work, bring the vehicle's current registration and title (if you have it), proof of vehicle insurance, and the vehicle identification number (VIN).

If you are registering a vehicle for the first time in Wisconsin or transferring a title from another state, bring the out-of-state title or bill of sale, a completed Wisconsin title process form (available on the DMV website), and proof that the vehicle has passed a Wisconsin emissions test if required in Rock County.

How to Schedule Your Appointment

Visit the Wisconsin DMV website and select "Schedule an Appointment" to see available times at the Janesville location. You will need to choose the type of transaction you need (driver's license, vehicle registration, title, etc.) and select a date and time that works for you.

If you prefer to call, reach the Rock County DMV at (608) 757-5500. Staff can tell you which documents you need for your specific transaction and help you find an open appointment slot. When you call, have your driver's license number or the vehicle's registration number ready.

Arrive 10 to 15 minutes early with all required documents. If you are missing paperwork, the office may not be able to complete your transaction, and you will need to reschedule. Bring originals and copies — do not rely on photos of documents on your phone.
