Barcode

The full barcode as printed on the item.

• We do not use this field for other numbers.
• No_barcode is checked if no barcode is present.
• If two barcodes are printed in the same box (a long one with 12 or 13 digits and a short one with 2 or 5 digits), enter them together with no spaces.
• If two separate barcodes are present, enter them separated by a semi-colon.
• The barcode field can be turned off for a series if no issues have a barcode.
• On the compare page a note will say if the number is a valid barcode according to the UPC or EAN standard. Note that publishers used barcodes which do not fulfil these standards, for example Marvel (till 1987) and DC (till July 1988) did use barcodes without the necessary check digit at the end. Such non-standard barcodes should still be entered.
  • UPC = 12 numbers
  • EAN = 13 numbers
  • the extra two numbers are called EAN-2, the extra five numbers are called EAN-5, both do not matter for validation purposes
