We will directly check the registration certificate (the big green book) and count the number of changes.

The core background report we provide (including basic information, mileage verification, and accident investigation conclusions) supports both Chinese and English outputs to ensure that overseas buyers or your end customers can read it without barriers.

We use an internationally certified electronic signature platform (such as DocuSign or Adobe Sign). Each signed contract generates a digital certificate with a timestamp and encrypted hash value, which has full legal defense effectiveness in international arbitration courts.
