A Dun's & Bradstreet Number, or D-U-N-S Number for short, is a unique nine-digit identification code attributed to an organisation and each physical location where business is conducted. It is used to establish a business's credit file for universal recognition. In order to register for Apple's Developer Program, your organisation must possess a D-U-N-S Number so that Apple may identify your organisation's identity and legal entity status.
Your organisation may already have a D-U-N-S Number. Before submitting a request application, use the D&B D-U-N-S Number Lookup tool to ensure that this isn't already the case. Otherwise, you will need to register with Dun & Bradstreet directly. Note, it is advised that you follow the Apple Developer Program prompts to secure a more timely response, closer to five business days.
Should your business be registered with the Australian Securities and Investments Commission (ASIC), the D-U-N-S Number registration will processed significantly quicker. Be sure to provide your organisation's ASIC details upon registering with Dun's & Bradstreet to ensure a faster turnaround on your application.
