WHAT IS A COA?
A COA, or “Certificate of Authenticity” is the sticker located on a computer system that has a 25-digit license key for the Windows Operating System, such as Windows XP or Vista. The COA verifies the validity of the operating system confirming that it is genuine. With the COA attached to the product, a legal copy of the operating system can be acquired from the original equipment manufacturer if the original restore media is lost (ie. Dell, HP, IBM, etc).
WHY DOES EPC LIST COA INFORMATION?
A lot of our wholesale buyers need this information. Many of our customers request that the COA information be placed in our ads so they can determine what machines to purchase according to the restore media they may have already or will be acquiring.
DOES THIS MEAN THAT NO OS IS INSTALLED?
Not Necessarily. Only about 50% of our computers being sold do not come with an OS installed. Please read the description thoroughly to determine what is and isn’t included with a particular item. If the computer advertised includes an operating system, there will be a NEW, Microsoft Authorized COA included with the sale (please see picture). The Buyer of a loaded system would then enter the 25 character alpha-numeric Product Key when setting up the computer for first use.
