ISSN

DATA: Numeric

LENGTH: Fixed

CHECK: Required

ISSN numbers are unique numbers that are printed on magazines and newspapers.

ISSN is not actually a separate bar code type. ISSN bar codes have a specific structure and can be encoded using EAN 13 bar codes with 2 digit supplemental codes.

Our JIT series of software products can automatically create ISSN bar codes with correct check digits. Simply select EAN-13 as the bar code type.

Example: For the June issue of a magazine with an ISSN of 7713543023, the message to encode is;

977771354302306

This message is formed by a fixed three digit country code of 977, followed by the ISSN number 7713543023.

The 2 digit supplemental code contains the issue number (i.e. January 01 , February 02, etc.), left padded with zeros. June is month 6, so this gives us the digits 06.
