format:

letter T 9 digits 1 check digit

e.g. T-345246800-1

To register an ISWC, the following minimal metadata must be supplied:

• title
• names of all composers, arrangers and authors, with their role in the piece (identified by role code) and their CAE/IPI number
• work classification code (CIS)
• identification of other works it is a derivative of

Note an ISWC identifies works, not recordings. ISRC can be used to identify recordings.
