The ISSN and EAN Barcodes
The EAN (European Article Number) for periodicals and series is based on the ISSN. The EAN begins with the prefix 977. It is followed by the ISSN code (without the hyphen and check digit) and the EAN check digit calculated according to the EAN rules.

Besides the EAN code the ISSN should be displayed legibly on every publication.
The Finnish ISSN centre assigns only the ISSN; the publisher is responsible for supplying the EAN barcode.
