Purchasing a VIN License

To purchase a VIN License, click the [Generate Auth Code] button. The Authentication Code will appear in the Auth Code field.

If the available VIN license slots are depleted, customers will not be able to place a VIN License order until Diesel Edge increases the license slot limit.

VIN License Validation Assistance

If the serial number or authentication code does not pass validation, an error message will be displayed. Customers should verify that the details entered precisely match those displayed in the EFILive software.

• Confirm the software version used to generate the authentication code.
• Ensure there are no extra spaces before or after the code.
• Hyphens are crucial.
• The serial number should be either 10 or 12 characters long.
• The authentication code must be exactly 20 characters.
• Make sure the license quantity limit has not been exceeded.
