One quick, easy, and accurate way of getting product or company information about any barcode is to use a barcode scanning app on your smartphone. 

These apps allow you to scan a UPC or EAN-13 barcode and check against the leading barcode databases on the internet (such as BarcodesDatabase.org, Gepir.org, Amazon.com, UPCdatabase.org, and others) to return product information based on the scanned barcode. There are many different apps available to choose from. 

Zebra Barcode Scanner is the recommended choice, available on iTunes for Apple devices and Google Play for Android devices.
