What is an IPI number and why do I have two?
An IPI number is a unique, international number linked to a composer/songwriter’s original name. Anyone who has a prefix in their surname (e.g. van or de) automatically receives two IPI numbers. A second spelling of your name is added to the international database to make it easier to identify you. It doesn’t matter which IPI number you use when registering your works. It’s up to you.
