EAN numbers, product codeLink

I am a first time user that requires barcodes for one of my products that will need to be scanned at shops. Where do I get the EAN numbers?
If you want to use this barcodes on your products you will need an unique code. Each country has a coding authority (or numbering association) which assigns codes to manufacturers and maintains a central database. The EAN system is under the overall direction of the International Article Numbering Association, based in Brussels, Belgium. Each country using the EAN system maintains a separate Article Numbering Association.
