Not sure which Microsoft Surface model you’re viewing? You can find out by lifting the kickstand on the back of the tablet and peeking underneath. There, you see the word Surface, as well as this identifying information:
Surface RT: These all-black, first-generation models list the term Windows RT beneath a Windows logo. You’ll also see the amount of storage listed as either 32GB or 64GB. The kickstand’s visible side shows a Windows logo.
Surface Pro: These first-generation models list the term Windows 8 beneath the Windows logo. You’ll also see the amount of storage, 64GB or 128GB.
Surface 2: These look much like the Surface RT tablets, down to the term Windows RT listed beneath the Windows logo. However, these second-generation tablets have a black front with a silver back. Beneath the kickstand, the amount of storage is listed as either 32GB or 64GB. Models with a 4G LTE data plan have a SIM card slot on the left edge below the volume rocker.
Surface Pro 2: These second-generation models list the term Windows 8.1 beneath the Windows logo. You also see the amount of storage, 64GB, 128GB, 256GB, or 512GB.
I recently purchased a surface RT/Pro keyboard from an online retailer through EBay. They just sent me the following message. 'It came to our attention that Microsoft surface keyboard serial number is attached to the keyboard’s retail box only.
The serial number of your Surface, needed for warranty and service information, is printed directly beneath the word Surface under the kickstand.
The serial number of a Surface keyboard is printed on the right edge of its spine — that raised edge that clicks onto the Surface when attaching the keyboard.
Before buying a used Surface on eBay, make sure the seller posts a clear photo of the information printed beneath the kickstand. That way you know exactly what’s being sold.
