ISMN

An ISMN barcode is a variant of EAN-13 with a prefix 979 that is used to identify printed music.

Also known as: International Standard Music Number, ISMN-13.

Variants:

  • ISMN-10 is a legacy format that was depreciated for public use.

Standards: ISO 10957, ISO/IEC 15420, BS EN 797, GS1 General Specifications.

Data and Options

  • The data should contain twelve or thirteen digits separated appropriately by dash characters -.
  • The data can also be provided in legacy ISMN-10 format start M- then eight or nine digits separated appropriately by dash characters -. This will be automatically upgraded to the ISMN-13 format.
  • The legacy option prevents ISMN-10 input from being upgraded to ISMN-13 and will result in a symbol that is obsolete and should not be used at point of sale.
  • If the last digit of the primary data is not given then the ISMN check digit is calculated automatically.
  • The primary data can optionally be followed by a space then two or five digits if an EAN-2 or EAN-5 add-on is required.
  • The includetext option should normally be supplied.
  • The guardwhitespace option enables the display of white space guard marks.
  • The following options are also relevant to this barcode symbology:
    • ismntextfont: Font name for text above symbol
    • ismntextsize: Font size for the text above symbol, in points
    • ismntextxoffset: Horizontal position of ISMN text, in points
    • ismntextyoffset: Vertical position of ISMN text, in points

Example ISMN

Identical symbols, input provided with and without an ISMN check digit:

0 0 moveto (979-0-2600-0043-8) (includetext)
/ismn /uk.co.terryburton.bwipp findresource exec
0 0 moveto (979-0-2600-0043) (includetext)
/ismn /uk.co.terryburton.bwipp findresource exec

The following ISMN-10 input will be automatically upgraded to a valid ISMN-13 symbol:

0 0 moveto (M-345-24680-5) (includetext)
/ismn /uk.co.terryburton.bwipp findresource exec
0 0 moveto (M-345-24680) (includetext)
/ismn /uk.co.terryburton.bwipp findresource exec

Example ISMN-10

Note that ISMN-10 is a legacy format not for use at P.O.S.

The following will generate an obsolete ISMN-10 symbol:

0 0 moveto (M-345-24680-5) (legacy includetext guardwhitespace)
/ismn /uk.co.terryburton.bwipp findresource exec
0 0 moveto (M-345-24680) (legacy includetext guardwhitespace)
/ismn /uk.co.terryburton.bwipp findresource exec
