EAN 8 Intro
An EAN-8 is a barcode and is derived from the longer European Article Number (EAN-13) code. It was introduced for use on small packages where an EAN-13 barcode would be too large; for example on cigarettes, pencils (though it is rarely used for pencils), and chewing gum packets. It is encoded identically to the 12 digits of the UPC-A barcode, except that it has 4 (rather than 6) digits in each of the left and right halves.
