Also the ISSN barcode is a special variant of the GTIN-13 code. The ISSN in principle is the ISBN for continuously released publications (e.g. magazines). The ISSN always has 8 digits. When transforming it into a barcode, the cyphers 977 are prepended to the ISBN. Barcody Express does this automatically, so you only have to enter the first 7 digits of the ISSN.

The digits 11 and 12 of the GTIN-13 code usually stay unused but can be used for special or double volume tagging.
