What is an International Unique Business Number (IUBN)?

The International Unique Business Number is a free, global, unique identifier for every registered company in the world.

Rather than creating yet another proprietary identifier to add to the many in existence, IUBN uses the identifier that all companies already have, the number issued by their government at the time of incorporation. To this, IUBN adds a country code and a checksum to ensure authenticity, and that's it - a single, unique, free-to-generate, free-to-use identity to use in thousands of situations.
