The best way to authenticate a Coach product is to call the company directly at 800-444-3611 and speak to a customer service representative with the serial number on the product, or email customer service on the Coach website. The Coach representative can verify the item's authenticity and serial code.
Another way to check a Coach handbag's serial code is to do an online search of the item by typing in the word "Coach," followed by the serial code. The Web search shows a picture of the bag associated with that particular serial code, if the handbag is authentic. The Coach brand of handbags is only authorized for sale at Coach Stores, Coach Outlet Stores and authorized department stores. The company's website posts a list of authorized Coach retailers.
Coach introduced a leather patch called a Creed Patch that was sewn onto the lining of its handbags in the mid-1960s. The company began incorporating serial numbers into the handbags in the mid-1970s.
