We also provide ISSN Bar Codes

The ISSN is the standardized international code which identifies any serial publication independently of its country of origin, its language or alphabet, or its frequency, medium, etc.

ISSN barcode symbols begin with "977" followed by the first seven characters of the ISSN. The last character in the symbol is a check character, which is generated by the bar code computer program. This ensures that the symbol checking algorithm is satisfied. When ordering ISSN bar code symbols all we need is the ISSN number and the desired add-on code. Our system automatically adds the "977" and calculates the proper symbol of the ISSN string.

For more detailed information and/or specification guides regarding ISSN symbols visit them on the web at www.issn.org.
