The VIN number of the BAIC Huansu S3 is located on the rear panel of the engine compartment, just below the windshield wipers. You need to open the engine hood to see it. Owners can also find it on the vehicle's registration certificate. Every car has a unique VIN number, also known as the Vehicle Identification Number. The VIN consists of a combination of letters A-Z (excluding I, O, Q) and numbers 0-9, totaling 17 characters, each with a specific meaning. 1st character: Represents the country of manufacture, indicating where the car was produced. 2nd character: Represents the manufacturer code, identifying the car brand. 3rd character: Represents the vehicle type code, indicating whether it's a passenger car, bus, or truck. 4th character: Represents the body type code, such as A-4-door sedan, B-4-door hatchback, or C-4-door extended sedan. 5th character: Represents the engine and transmission code. 6th character: Represents the occupant protection system code. 7th-8th characters: Represent the vehicle grade code. 9th character: Represents the check digit, used to verify the accuracy of the VIN. 10th character: Represents the model year code, helping to identify if the car is a new model or an older stock. 11th character: Represents the assembly plant code, with "0" indicating factory assembly. This can help determine if the car is imported. 12th-17th characters: Represent the production sequence number, used for recalls if needed.

I've been driving the BAIC Huansu S3 for several years, and there are some tricks to finding the VIN. The most common location is at the lower left corner of the windshield on the driver's side—just squat down and look through the glass to see a long string of letters and numbers. If you can't find it there or if it's covered by a sticker, don't worry. Open the hood, and you'll usually find the VIN stamped on the passenger-side frame rail near the strut tower. Still can't locate it? Squat down and check the black sticker near the passenger-side door sill—it’s often printed there too. By the way, the VIN is definitely recorded on the vehicle registration and insurance documents, so you can cross-check there.

The Vehicle Identification Number (VIN) is like the car's ID card, essential for inspections and transfers. Owners of Huansu S3 should memorize its location. The most visible spot is along the lower edge of the front windshield, directly in front of the driver, where a metal plate with the 17-digit number is engraved and visible from outside. Don't overlook the engine compartment either, especially the top of the radiator frame or the front engine beam, where stamped numbers are often found. Additionally, check the passenger door; labels are usually affixed below the B-pillar or on the sill trim panel. Locations may vary slightly depending on the model year, but these three areas are the most common. Take the time to check all these spots—it's worth the effort.

Here are three practical locations to find the chassis number of the Huansu S3: First, check the lower left corner of the windshield—the metal plate is embedded in the plastic trim. Second, lift the hood and look at the side of the chassis longitudinal beam above the right front wheel; using a flashlight will make it clearer. Third, remember to inspect the edge of the black plastic pedal below the passenger door frame. At least one of these spots will reveal the 17-digit stamped combination of letters and numbers. When inspecting the car yourself, the fear is not being able to locate it—knowing these spots in advance saves you from unnecessary hassle.
