- 1). Call the product maker and ask for a description of the product's Certificate of Authenticity. Most genuine certificates contain at least the product maker's name, contact information, a statement of authenticity and specific details about the product and/or the product maker (for example, a product number or barcode). The product maker may have also designed the C.O.A. in a particular shape or with security features such as watermarks, holograms, special inks or micro-printed information or metallic security threads.
- 2). Ask the product maker for the address of a nearby authorized representative or expert trained to recognize the official C.O.A. associated with your product. As many criminals forge Certificates of Authenticity, an in-person authentication is required to guarantee that your Certificate of Authenticity is genuine---especially if you find initially that your C.O.A. doesn't match the product maker's description completely (has missing information, incorrect ink colors and/or additional text or marks).
- 3). Take your C.O.A. and product to the authorized representative for evaluation. If it turns out that you own a copy of an original product or a stolen original that re-sold with a forged certificate, report the crime as instructed by the representative
