Quick answer
A California VIN verification (REG 31) is required when DMV cannot confirm vehicle identity from documents alone—common for out-of-state transfers, certain corrections, kit vehicles, and some salvage cases. Verifications must be performed by authorized DMV, CHP, or licensed verifiers.
- Typical processing
- Verification itself is usually same day; registration approval still depends on the full document package.
- Fees
- Verifier fees vary by location. DMV may charge additional fees as part of the broader registration transaction.
Step-by-step
Step 1
Determine if verification is required
Check DMV transaction codes, out-of-state status, and whether VIN data mismatches DMV records.
Step 2
Schedule with an authorized verifier
DMV field offices, CHP, and licensed verifiers can complete REG 31. Mobile verifiers may come to your location.
Step 3
Prepare the vehicle for inspection
Clean VIN plates, bring keys, and ensure the vehicle starts if operability affects inspection.
Step 4
Submit REG 31 with registration application
Attach verification to REG 343 or other applications. Mismatched data without REG 256 explanations triggers RDF.
Requirements
- Vehicle must be presented unless an exception applies for specific transaction types.
- VIN plate, federal label, and engine numbers (when required) must be legible and match documents.
- Any discrepancies in year, make, or body type must be explained with supporting documents.
