The D-U-N-S Number. Issued by Dun & Bradstreet, the Data Universal Numbering System (D-U-N-S) assigns a unique nine-digit identifier to your registered business. If you’re setting up a developer account as a company or organization, it’s mandatory  that you have a D-U-N-S number. While it’s optional for individual developers, many enterprise-level submissions on both platforms require it. Knowing when and how to get your D-U-N-S number not only speeds up your app store approvals but also ensures your app release doesn’t get delayed by incomplete credentials. In this guide, we’ll walk you through exactly how to apply for a D-U-N-S number, how long it takes, and what you need to prepare, so you can move forward without the bureaucratic roadblocks.

  • Check your DUNS number using the tool at D&B DUNS Lookup Tool.
  • Check the D&B DUNS Lookup Tool with your official business name and country and city information

Common Issues and How to Resolve Them?

“My business is not listed”

The DUNS lookup will not display your company so you must complete the application process through the D&B website. Your business details must be correct and consistent with official records. A business email provides faster verification during the process.

“I have a DUNS number but Apple says it’s invalid”

Apple identifies this problem when your DUNS number for App Store does not match what they have in their system. Verify that your company name and address along with legal format match exactly. Small discrepancies such as “Inc.” versus “Incorporated” will create problems during the process.

“My address doesn’t match”

Update your business address through the D&B portal before Apple or Google identify it as incorrect. The systems need several business days to complete their synchronization process. All your business records must display the new address information.

“It’s taking too long—can I expedite it?”

Dun & Bradstreet allows you to request faster review through their direct contact channels. The review process takes less time in the U.S. yet international users sometimes experience longer delays. You should have backup documentation ready to present upon request from D&B.
