EAN-2 is an optional additional bar code to the right of a EAN-13 or UPC-A bar code, used on product packaging for checkout scanning. It encodes an extra two digits in addition to the main UPC or EAN code, used for supplementary information. Typically it is used on periodicals to distinguish issues; the two digits can represent the month or week of the given issue (repeating every year). If the publisher wants to permanently distinguish all issues in the entire run of a publication, as comic book publishers do with direct-sale issues, they need more digits, so the EAN-5 code (with 5 digits) is better for this purpose.
