Two used Teslas can look identical in the Tesla app. Only one of them keeps free Supercharging after you buy it. The difference is a single option code. SC01 transfers to the next owner on a private sale. SC05 gives the same free charging and ends the day the car changes hands — and both look exactly the same on the screen in the car. SC01Check reads the option codes straight from Tesla's own records for one specific VIN, and tells you what actually transfers. WHAT A CHECK TELLS YOU • Free Supercharging — whether it is SC01 and transfers, or SC05 and ends at the sale • Full Self-Driving — bought outright and staying with the car, a monthly subscription that stops when you buy, or not fitted at all • Every factory option code — paint, wheels, interior, seating, towing, audio, autopilot hardware • Battery state of health, measured against the pack's original capacity • Original MSRP and how the car was specified when it left the factory • Open safety recalls POINT YOUR CAMERA AT THE VIN No typing seventeen characters off a door jamb. Photograph the label and the VIN fills itself in. KEEP TRACK OF CARS YOU ARE CONSIDERING • Every car you check is saved, and reopening a report you have already run is always free • File them as "I own this", "Watching", or "I used to own this" • Add private notes to any car • Get an email when a watched car's Supercharging or Full Self-Driving status changes, or when a new safety recall is issued against it • Share a report with a seller, a mechanic, or whoever is helping you decide VEHICLE HISTORY REPORTS Full CARFAX and AutoCheck reports are available for any VIN, alongside the factory data. WHAT IT COSTS Two free checks when you confirm your email address. They do not expire. After that, credits start at 10 for $4. Credits never expire, a car you have already checked is always free to reopen, and a VIN that is not a Tesla costs nothing at all. Credits are purchased on sc01check.com. WHERE THE DATA COMES FROM Direct access to Tesla's backend systems — the manufacturer's record for that specific car, rather than a guess based on the VIN pattern. SC01Check is an independent service. It is not affiliated with, endorsed by, or operated by Tesla, Inc., CARFAX, Inc. or Experian.
