3002.VIN OCR

Brief Summary:

Photos containing VIN codes captured from locations such as the vehicle nameplate, driver’s license, or front windshield can be processed through an OCR recognition program to convert them into a 17-character vehicle identification number (VIN). Notes:

Ensure the photo is free of glare during photography.

Compress the image before uploading to prevent upload failures due to large file sizes.
