How to Submit a VIN Specs Correction

If a vehicle's decoded specifications differ from its physical build sheet:

  • Vehicle Brand & Model Year (e.g. 2024 BMW 330i or 2023 Tesla Model Y)
  • Character Position in Question (e.g. 4th digit for body type or 11th digit for assembly plant)
  • Official Build Document or Window Sticker Reference confirming the correct factory designation
