What proof do 4S stores use to verify genuine parts?

4S stores generally retain the original factory codes of replaced parts. When customers question the authenticity of parts, 4S stores may use these codes to verify the components. Here is relevant information about automotive 4S stores: 1. Introduction to 4S stores: A 4S store, fully named Automobile Sales Service 4S Store, is a car sales enterprise that integrates four functions: vehicle sales, spare parts, after-sales service, and information feedback. 2. Advantages of 4S stores: Brand advantage - Most automotive 4S stores deal with car brands that have good brand effects, strong competitiveness, and relatively large market shares. Complete and standardized service system - The core competitiveness of automotive 4S stores lies in winning customers through high-quality services.

I've been in the automotive repair industry for over a decade and have seen various methods for verifying genuine parts. When dealerships sell components, the most straightforward proof is the packaging – authentic blue boxes or anti-counterfeit bags bearing the car brand's logo, such as Toyota or Volkswagen, which are specially designed and difficult to replicate. I also advise customers to check the serial number label; entering it on the official website can verify authenticity, as counterfeit items often show as invalid. Additionally, dealerships provide warranty cards or electronic invoices stating the manufacturer's guarantee and authorization number—don’t forget to request a receipt noting the part as genuine. On a related note, when helping a friend purchase headlights, I returned them immediately due to loose packaging, as substandard parts could lead to accidents. Spending a bit more for safety is worthwhile. I recommend photographing details before each purchase and consulting someone knowledgeable about cars for confirmation—it’s more reliable.

I just bought a car not long ago and often go to the 4S store to replace parts. I've figured out how to verify genuine parts. At first glance, check the packaging—the brand logo should be clear and undamaged, with complete anti-counterfeit stickers. The staff also scanned a QR code for me, which displayed authentic product information, and some used an app to verify the serial number. The invoice clearly states the original supply source, and you can also request a paper certificate showing the batch number. Regarding my experience, last time I spent a lot on replacing tires, but after confirming their safety through the packaging and app, I felt more at ease driving on the highway. When doing it myself, I compared the material and texture—the genuine parts felt sturdier. Don’t forget to take photos with your phone as evidence to prevent disputes. Overall, the 4S store mechanism is reliable, but it doesn’t hurt to be extra careful to avoid future troubles.

From the perspective of a 4S dealership, providing original factory certification is straightforward: the packaging must be intact and undamaged with clear logos; the electronic system checks the serial number and prints a confirmation slip for you; the invoice includes an authorized mark or QR code for traceability. This way, purchasing parts is worry-free and eliminates concerns.
