What is a D-U-N-S® Number and How to Set it Up

The D-U-N-S Number is a unique nine-digit number that identifies business entities on a location-specific basis. Assigned and maintained by Dun & Bradstreet (D&B), the D-U-N-S Number is widely used as a standard business identifier.

Your D-U-N-S Number will be used to check the identity and legal entity status of your organization as part of our enrollment verification process for joining the Apple Developer Program or the Apple Developer Enterprise Program.
