The ISWC is an ISO-approved standard. The International ISWC Agency, which is appointed by ISO, is responsible for the overall ISWC system maintenance and administration.
Short for International Standard Works Code, an internationally recognized reference number for the identification of musical works. The code that is applied to a musical work is permanent and stays with the work even when it is transferred across national borders. An ISWC begins with the letter “T”, followed by a nine-digit unique number (from 00000001 to 999999999), and an additional check digit at the end.
