The ISNI—the International Standard Name Identifier—is the global standard number for identifying contributors to creative works such as books. It consists of 16 digits. Where an ISBN is assigned to a book, an ISNI is assigned to an author, illustrator, or publishing house imprint.
ISNIs can be helpful for authors of multiple works and those who have names similar to other authors. Publishers with imprints might also find having an ISNI useful to distinguish themselves from other publishing companies or imprints with similar names.
