Screen protectors do not have serial numbers, so this field can be left blank in your registration. Locate the model number at the bottom of each device's packaging. NOTE: If your product is not on the list and you can’t find the product numbers on its sticker or on the device itself, try to check its package or box’s exterior sides and look for its barcode section and/or sticker. NOTE: The model number is also called the Part # of the product or device.īelow are the locations of the different Belkin products’ model, version and serial numbers. However, where these numbers are printed depend on the type of product you have. For most products, this information is printed on the product sticker. Firmware updates, troubleshooting, or product registration of your Belkin devices may require you to search for product numbers such as the model, version, and serial number.
