Engine numbers and chassis numbers pose certain risks. 1. Chassis number. Commonly referred to as the vehicle identification number or 17-digit code, this code is equivalent to the car's ID card, containing almost all information about the vehicle, including production date and place of manufacture. 2. The engine number is unique. Each motor vehicle has a separate engine, which carries the specific engine model, the exact production time of the vehicle, the production location code, and other important vehicle information that is not allowed to be altered or replaced. 3. By logging into the traffic management bureau's government service website and entering your license plate number and chassis number, you can access detailed information such as the owner's phone number, address, and postal code. In other words, with just the license plate number and chassis number, one can easily obtain the owner's information. 4. A common issue is the so-called 'number copiers' who specialize in copying parking contact numbers. This group is active in various parking lots, often copying parking contact numbers, vehicle models, and license plate numbers, then categorizing them by vehicle model before selling them to businesses for promotional purposes.

Having driven long distances for years, I fully understand the serious consequences of leaking your engine number and VIN. If these fall into the wrong hands, criminals could forge your vehicle's identity. For instance, they might clone an identical car for theft or traffic accidents, potentially making you the scapegoat during police investigations. In used car transactions, such leaks can cause your car's value to plummet as potential buyers fear risks. From a privacy perspective, your personal information like purchase records could be stolen for scam ads or credit fraud. I always remind friends to cover these numbers when taking photos for repairs or sales, and never casually post them online. Simple daily vigilance can prevent major disasters. I'm also careful when checking repair invoices to ensure mechanics haven't recorded them. Though a small leak, the hidden dangers are endless – protecting these numbers is like safeguarding your house keys.

As an average car owner, I'm always concerned about personal information leaks. The engine number and VIN are like a car's ID card - if exposed, the consequences can be severe. The worst-case scenario is identity theft: scammers could use these numbers to create fake vehicle documents or impersonate you in illegal transactions. For example, common fraud cases on car-selling platforms where number leaks lead to transaction disputes, leaving you with debt or financial loss. Insurance-wise, it's equally bad - malicious actors could alter information to commit insurance fraud, leaving you at a disadvantage when filing claims. Privacy-wise, associated personal data could be extracted for harassing calls or online scams, bombarding you with disturbances. I believe we must stay vigilant when handling vehicle matters - never display these numbers on social media, and always scrutinize contract terms during repairs. A minor leak can trigger a chain reaction, destabilizing your life, so constant vigilance in protection is essential.

Having been in the car enthusiast circle for over a decade, from an economic perspective, the leakage of engine numbers and chassis numbers poses significant risks. The primary concern is financial disputes: if malicious individuals use these numbers to forge documents for used car transactions or insurance claims, you could suffer monetary losses or damage to your credit. Indirectly, it affects the vehicle's value—for instance, prices might be maliciously driven down after a leak, making resale difficult. Privacy breaches also lead to unwanted advertising and commercial exploitation of personal information. I once experienced a situation where my car's numbers were leaked after a repair, nearly involving me in an insurance fraud case, but fortunately, it was resolved in time. Protection is simple: cover the numbers during registration or photography, and avoid keeping electronic copies.
