My friend recently encountered the issue of checking the vehicle compliance certificate number when buying a car. He directly obtained all vehicle documents from the 4S store salesperson, with the compliance certificate number clearly stated on the purchase invoice and the vehicle conformity certificate. If you don't have these materials, the simplest method is to contact the original dealer, provide the Vehicle Identification Number (VIN), and they can retrieve the records for you. If you can't reach them or they've relocated, it's recommended to visit the local vehicle management office window for inquiries. Bring your ID card and vehicle registration certificate, and the staff can print it out after verification. Nowadays, many places also have online platforms. You can log in to the Traffic Management 12123 App, enter the VIN and license plate information to check, which is quite convenient. However, be careful not to casually input information online; protecting privacy and security is paramount. Although this checking step may seem minor, it's crucial for subsequent registration and transfer processes. Don't find it troublesome; checking thoroughly will save you worries later.

Having dealt with car dealerships multiple times, I've helped clients check vehicle certification numbers. It's usually attached to the back of your purchase invoice or included in the new vehicle delivery checklist. If you can't find it, don't panic - contact the 4S store where you bought the car for backup documents, or use the vehicle's VIN to check on the DMV's official website. I also recommend keeping the purchase contract as evidence to prevent disputes during future used car transactions. Checking this number is actually quite important as it verifies the vehicle's authentic origin. Some people skip this step to save trouble, only to encounter transfer delays later, wasting both time and money. In short, starting from the source is most reliable - just fill out an application form at relevant departments when needed, and never trust verbal promises.

I just checked the vehicle certificate, and the method is quite simple. Usually, when purchasing a car, the salesperson will write the number on the invoice or document bag, so you can check it directly. If you can't find it, you can visit government websites such as the traffic management service desk, enter the license plate number and engine number, and the system will automatically display the number and related certifications. Using a mobile app is even more convenient, such as the Traffic Management 12123 app—just fill in the information, and the results appear instantly. Remember to verify your personal information accurately during the check to avoid errors. This step is necessary for insurance or selling the car, so checking early brings peace of mind.
