You can request a D‑U‑N‑S number directly from Dun & Bradstreet by filling out their online “D‑U‑N‑S Number Request” form; for companies outside the U.S. you’ll use the international portal (or the local D‑B office’s website) and provide your legal business name, registration number, and the address that appears on your official government documents. After you submit the form, D‑B usually verifies the information by phone or email and then issues the number within 5‑10 business days—sometimes faster if you have a “D‑U‑N‑S Number for Apple” shortcut, which Apple’s support can trigger for you. Once you receive the 9‑digit D‑U‑N‑S, add it to your Apple Developer enrollment and give Apple a few more days for their internal check. The most common hiccup is a mismatch between the address on your D‑B record and the one Apple has on file (e.g., a PO‑box versus a street address, or a different spelling of the city); to avoid this, make sure the address you enter in the D‑B request matches exactly what appears on your business registration, tax filings, or utility bills. If Apple flags a discrepancy, you can contact D‑B to update the record and then ask Apple to re‑run the verification, which usually resolves the issue.
