How to fill out California REG 17

The form that gets your personalised plate off a car you are selling and onto the next one - or into storage, or back to the DMV. Ordinary California plates stay with the car; these do not, and this is the only way to move them.

Written against REG 17 (Rev 2/2025), issued under California Vehicle Code 5060 and 5106. Take the plate off before the buyer takes the car, not after. Once the vehicle is out of your hands, retrieving a plate from a stranger is a conversation nobody enjoys.

Two documents, and they are not the same thing. Take the blank REG 17 from the dmv.ca.gov copy so you get the revision that is current today.

Rules that decide whether it is accepted

Every line here was read off REG 17 (Rev 2/2025) itself — the PDF is here — and off the California Department of Motor Vehicles pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
