Why You Need a D-U-N-S Number

A D-U-N-S number is required to enroll in the Apple Developer Program as an organization. Without one, you can only enroll as an individual, which means your personal name appears on the App Store instead of your company name.

For any team or business publishing apps, enrolling as an organization is essential for professional branding, team management in App Store Connect, and building credibility with users.

Step 1: Check if Your Organization Already Has a D-U-N-S Number

Many businesses already have a D-U-N-S number without knowing it. Dun & Bradstreet assigns numbers to millions of businesses worldwide.

Visit the Apple D-U-N-S lookup tool and search using your legal business name and address. If your organization appears, note the D-U-N-S number and skip to Step 5.

Step 2: Request a New D-U-N-S Number

If your organization doesn’t appear in the lookup results, you can request a new D-U-N-S number directly through Apple’s tool. This is faster than applying through Dun & Bradstreet’s website.

Click the “Submit your information” link on the lookup results page and fill in your business details.

Step 3: Prepare Your Business Information

You will need to provide:

Legal business name - must match your official registration exactly
Headquarters address - the physical address of your business
Mailing address - can be the same as your headquarters
Phone number - a working number where D&B can reach you
Contact name and title - an authorized representative of the company

Make sure all information is accurate and consistent. Discrepancies between your D-U-N-S record and your Apple Developer enrollment are the most common cause of delays.

Step 4: Wait for Processing

When submitted through Apple, D-U-N-S number requests typically take up to 5 business days. D&B may contact you by phone or email to verify your information.

If you apply directly through D&B instead, processing can take up to 30 days.

Step 5: Verify Your D-U-N-S Number

Once you receive your D-U-N-S number, go back to the Apple lookup tool and search for your organization again. Confirm that:

Your organization name appears correctly
The address matches what you plan to use for enrollment
The D-U-N-S number is active

If any details are wrong, contact D&B to update them before proceeding.

Step 6: Enroll in the Apple Developer Program

With an active D-U-N-S number, go to developer.apple.com/enroll and begin the enrollment process. Select “Organization” as your entity type and enter your D-U-N-S number.

Apple will verify your information against D&B’s database. The enrollment review typically takes 1-2 business days after submission.

Common Issues and How to Fix Them

Name mismatch: Your company name must match exactly between your D-U-N-S record and Apple enrollment. Even small differences like “LLC” vs “L.L.C.” can cause rejection. Contact D&B to correct any discrepancies.

Address not found: If your business is new or recently relocated, your address may not be in D&B’s database yet. Request an update and allow a few days for it to propagate.

Multiple D-U-N-S numbers: Each physical location gets its own D-U-N-S number. Use the one that matches your primary business address.

International businesses: D-U-N-S numbers are available globally through D&B’s international offices. Processing times vary by country but the Apple lookup tool works worldwide.
