N/A ISSN bar codes are EAN‑13 symbols that encode the first 7 digits of an ISSN prefaced by a special "land of serial publications" country code (977) and followed by a 2‑digit price code. In addition to the 13 digits encoded by the symbol, the complete 8‑digit ISSN is usually printed in human‑readable format along with the symbol. The checksum digit is not encoded. The ISSN bar code descriptor contains two sets of fields for specifying the placement, typeface, and style of these two separate text strings. In an ISSN symbol, the data must consist of an 8‑digit ISSN, followed by a 2‑digit price code. The data is optionally followed by a 2‑ or 5‑digit add‑on code. If this code appears in the data, then an EAN‑13+2 or EAN-13+5 is generated. The add‑on code is encoded in the +2 or +5 section of the symbol. The last digit of an ISSN, the checksum digit, may be an X (ASCII 88). To enhance readability, "-" (ASCII 45) may appear anywhere in the data. In an ISSN text printed with the symbol, "-" is always placed in a fixed position. The checksum digit is not encoded in the symbol. It is required in the data only for inclusion in the ISSN text printed with the symbol. A calculation in Forms and Bar Code Card does not verify or replace the ISSN checksum digit. The following conditions produce an error message: • Lengths other than 10, 12, or 15 digits • Any character other than a digit or a "-" except for an X in the eighth digital position Cursor positioning is handled similarly as one‑dimensional symbologies. If bytes 5 or 8 are changed from their default values, then the parameters of the bar height and the bar and space width assume new dimensions, based on the new units. In other words, the parameters are in units, and if the measurements of the units change, so does the physical printed bar code. If any of the parameters are set to 0, then the default value assigned in the table is used.

ISSN bar codes are EAN
‑
13 symbols that encode the first 7 digits of an ISSN prefaced by a special “land of serial
publications” country code (977) and followed by a 2
‑
digit price code. In addition to the 13 digits encoded by
the symbol, the complete 8
‑
digit ISSN is usually printed in human
‑
readable format along with the symbol. The
checksum digit is not encoded. The ISSN bar code descriptor contains two sets of fields for specifying the
placement, typeface, and style of these two separate text strings.
In an ISSN symbol, the data must consist of an 8
‑
digit ISSN, followed by a 2
‑
digit price code. The data is
optionally followed by a 2
‑
or 5
‑
digit add
‑
on code. If this code appears in the data, then an EAN
‑
13+2 or EAN-13+5
is generated. The add
‑
on code is encoded in the +2 or +5 section of the symbol. The last digit of an ISSN, the
checksum digit, may be an
X
(ASCII 88).
To enhance readability, "
-
" (ASCII 45) may appear anywhere in the data. In an ISSN text printed with the symbol,
"
-
" is always placed in a fixed position.
The checksum digit is not encoded in the symbol. It is required in the data only for inclusion in the ISSN text
printed with the symbol. A calculation in Forms and Bar Code Card does
not
verify or replace the ISSN checksum
digit.
The following conditions produce an error message:
•
Lengths other than 10, 12, or 15 digits
•
Any character other than a digit or a "
-
" except for an
X
in the eighth digital position
Cursor positioning is handled similarly as one
‑
dimensional symbologies.
If bytes 5 or 8 are changed from their default values, then the parameters of the bar height and the bar and
space width assume new dimensions, based on the new units. In other words, the parameters are in units, and
if the measurements of the units change, so does the physical printed bar code.
If any of the parameters are set to
0
, then the default value assigned in the table is used.
