Don't pay for a sticker. Verify the internal serial number of any Phone, Laptop, or Accessory against the manufacturer's global database to prove it's authentic.
Clones use real Serial Numbers. A fake iPhone 14 can have a valid serial number copied from a real one.
The Golden Rule: When you check the serial number on the websites below, verify the Attributes (Color, Storage, Model Year). If the website says "Red 64GB" and you are holding a "Blue 256GB" phone, IT IS A FAKE.
Verify iPhone, Samsung, Pixel, and others.
iPhone, iPad, AirPods, Watch
Galaxy S-Series, A-Series, Tabs
Tecno, Infinix, Xiaomi, Pixel
Crucial for verifying specs (Ram/Processor) on used laptops.
Sellers in Computer Village often take old laptops, edit the Registry to make them look newer (e.g., changing "Core i5 2012" to display as "Core i7 2018"), and polish the casing.
The BIOS cannot be faked easily. Whatever specs you see there are the real ones.
Right-click Desktop > Display Settings. If a "4K Laptop" shows "1366x768", it's a low-end screen swap.
For MacBooks: Click Apple Logo > About This Mac > System Report > Power. If cycles are > 500, the battery is old.
Now make sure it wasn't reported stolen by the previous owner.
