Assigning VIN to Trailers
Arizona law requires a specially marked serial number (AZ SNO) for homemade trailers missing a proper VIN. Even for trailers whose VIN or other identifying number has been altered, removed, defaced, destroyed or otherwise illegible, it can be restored with a new identifier that contains its information.
