Find your VIN

Your Vehicle Identification Number (VIN) is the 17-character code that identifies your car, and every map code we generate is tied to it. On a Mercedes the VIN sits in three reliable places. Any one of them is enough.

Where the VIN is on your Mercedes

• Windshield, on most models.

  • Stand outside the car and look through the lower-left corner of the windshield on the driver's side, right where the glass meets the dashboard.
  • The VIN is stamped or printed on a small metal plate. Good light or a phone flashlight makes it readable.

• Driver or passenger door jamb.

  • Open the driver's door and look at the door jamb and B-pillar for a sticker or metal plate with the vehicle details. The VIN is printed there.
  • Some models carry an identical label on the passenger side.

• Registration documents, which always list it.

  • Your registration certificate, title document, insurance paperwork, or service booklet will show the VIN.

How to read and enter the VIN

• A VIN is exactly 17 characters, letters and numbers. Mercedes VINs never use the letters I, O, or Q.
• Enter it in uppercase with no spaces, for example WDD2120271B12XXXX.
• If the windshield plate is hard to read, photograph it and zoom in. Copying it by eye is where transcription mistakes come from.
• Compare the VIN from two places, the windshield or door label against the registration document. Matching numbers mean you have it right.

Need a map license key?

After finding your VIN, use it to generate a map license key. A Mercedes navigation update run from a USB stops partway and asks for that key before it will install.

Follow the map code guide for the whole process, or use the form below once you've created your USB.
