The stitching on a Gucci belt should be literally perfect. Not nearly perfect – actually perfect. You are paying for the high quality that this designer brand is known for. Each stitch should be straight across (not slanted) and exactly the same size as every other stitch. If there are noticeable mistakes in the stitching, you should consider that it is probably a fake Gucci belt. Authentic Gucci belts are made with perfect craftsmanship. If you notice any fraying of the materials on the belt, it is almost certainly a fake. This is especially true if you buy a “new” Gucci belt and it arrives with some fraying. If you notice any imperfections in the materials, this is a sign that you probably have a fake belt on your hands. Fake Gucci belts often have clip on belt buckles, whereas authentic Gucci belt buckles are typically soldered onto the larger portion of the belt. None of the models of authentic Gucci belts include a button holding the belt buckle in place. Some models have screws on the back of the belt buckle, while others don’t. You’ll need to check the specifics of each model. Authentic Gucci belts have a stamp on the inside portion of the belt, whereas this feature will be missing on their fake counterparts. In some newer belts, the stamp is near the buckle, while some of the older belts stamp the belt toward the center, length-wise. The stamp should say the brand name, “Made in Italy,” and include an identifying number. An authentic Gucci serial number should be 21 digits long. Typically, the number should begin with “114” or “223.” If your number begins with “1212,” it is definitely a fake. This is a common serial number given to fake Gucci belts.
