A D-U-N-S Number is a number that is used to identify your business. D-U-N-S stands for Data Universal Numbering System, a system developed in the 60s by the Dun & Bradstreet (D&B) company for their own business. It has become a standard to identify a business and Apple uses it to verify the identity of your company.

A DUNS number is a unique nine-character identification number Dun & Bradstreet provides free of charge.

The ‘DUNS’ system was quickly adopted worldwide and it’s used by Apple to verify you’re a registered business and the identity of your Company.

Where do I register a DUNS number?

Before you start, use the DUNS Number look up tool to check if you already have one. If your company is not in the database, you can submit your information and get your DUNS number.

How long does it take?

Obtaining a DUNS Number for your business is quite straightforward. The process usually takes about five working days.

Once you receive your number, please allow up to 2 business days for Apple to receive your information from D&B. After this, you can apply for the Apple Developer Program as a company.
