How to Register an Out-of-State Vehicle in California

March 1, 2026 6 min read

Step 1: Gather your documents

You'll need your out-of-state title (or registration if the title is held by a lender), proof of insurance, and a valid ID. New residents generally must register within 20 days of establishing residency.

Step 2: Get a VIN verification

California requires a VIN verification for out-of-state vehicles. This is where we come in — a licensed verifier completes your REG 31 at your home or office, confirming the VIN matches your title.

Step 3: Smog check (if required)

Most gasoline vehicles need a smog inspection before registration. Check whether your vehicle and model year require one.

Step 4: Submit to the DMV

Bring your title, completed REG 31, smog certificate, proof of insurance, and payment for fees to the DMV (an appointment is recommended). With the VIN verification already done, this step goes much faster.
