Recover product key

How can I recover a lost product key for a windows server 2016 license? I have the proof of purchase that contains the COA (certificate of authenticity) bar code, I would imagine that based on this I would be able to either get the corresponding product
key or a replacement one. The product key was not used on the server as it was never taken out of the envelope that contained it so I can't recover it from the actual server.
