The VIN number of a smart is located inside the trunk. The owner needs to lift the rear trunk insulation mat, and the VIN can be seen at the connecting corner between the insulation mat and the cover panel. The Vehicle Identification Number (VIN) is a unique code consisting of seventeen alphanumeric characters, used to identify the manufacturer, engine, chassis number, and other performance data of the vehicle. The dimensions of the Mercedes-Benz smart are 2695mm in length, 1663mm in width, and 1555mm in height, with a wheelbase of 1873mm. In terms of power, this car is equipped with a 0.9T turbocharged engine and a 1.0L naturally aspirated engine. The 0.9T engine delivers a maximum torque of 135 Nm and a maximum power of 66 kW, while the 1.0L engine produces a maximum torque of 91 Nm and a maximum power of 52 kW.

The VIN number of my old was located at the lower left corner of the windshield, right in front of the driver's position, where you could see a combination of letters and numbers through the glass. Some newer models hide it in more discreet spots—you might need to open the engine hood and look for a metal plate near the front radiator support. If it’s not in either of these places, another possible location is under the passenger seat carpet, where there might be a stamped metal plate. If you still can’t find it, it’s best to check the vehicle manual, as every manual includes a diagram of the exact location. Alternatively, you can directly compare it with the VIN on the vehicle registration document. I remember once during a heavy rainstorm when the windshield was too blurry to see, I used my phone’s flashlight pressed against the glass to take a photo—that method worked really well.

As someone who often helps friends inspect cars, I'm very familiar with the VIN locations on Smart cars. Most can be found directly at the bottom of the windshield on the driver's side, visible without any tools. The second location is in the engine compartment on the radiator support near the front, where there's an aluminum plate with the VIN. The third spot might be under the passenger floor mat - you'll need to move the seat fully forward and lift the carpet. One detail to note: older models may not have the windshield marking and rely entirely on the engine compartment plate. When inspecting, always verify consistency across all three locations to prevent tampering. Regularly wipe the plates with a soft cloth to prevent dust buildup, especially the engine compartment one which tends to accumulate grease.

I had quite a time locating the VIN on my 2015 . At first, I couldn't find it on the windshield, but later discovered a metal plate on the crossbeam behind the battery in the front right corner of the engine compartment. Newer models now have an additional location - an embossed code under the front passenger floor mat. I recommend keeping a small pry bar handy for lifting the carpet when needed. If the VIN location is dirty, avoid using a wire brush - just gently wipe it with a damp cloth. If it's hard to read, take a photo and send it to the dealership's customer service for verification - much easier than crawling under the car.

Last time when I took my for maintenance, the technician specifically taught me the key points to locate the VIN. The first choice is to check through the lower left corner of the windshield, aligning the angle with the wiper pivot position. The second option is to open the engine hood—80% of cars have a palm-sized plate fixed with rivets near the fan bracket. Only consider under the seat as a last resort, as this spot is usually covered by floor mats. A special reminder: avoid using your phone to take prolonged photos against the engine in high summer temperatures, as the plastic plate might be too hot to touch. If visibility is poor on rainy days, reversing the car into a garage or under shade works better than using a flash.

Remember the first time I helped a neighbor locate the VIN on their car, I noticed variations across different model years. For pre-2010 models, it was always on the firewall in the engine compartment; post-2010 versions mostly moved it to the windshield corner. Newer models now add an engraved code on the steel plate under the passenger seat – tilt your phone flashlight to reveal it clearly. Here's a pro tip: The annual inspection sheet and insurance documents both print the full VIN, always cross-check paper records when struggling to locate it. If rain or fog obscures the metal plate, rub lipstick or chalk into the recessed characters and transfer the impression onto white paper – this method never fails.
