Is there a master database where I can enter my barcode and product information that way everyone in the world knows that those are my numbers, which of my products that they are on and how much they should be sold for?
Unfortunately not. Different individuals and companies have attempted to start up databases, but no one is 100% correct or complete. You will need to provide your barcode and product information to everywhere you want to be found.
