Get your D-U-N-S number

A D-U-N-S number is a free, nine-digit ID that Dun & Bradstreet assigns to a business. Apple and Google both require it to confirm your company is a real organization before they'll let you publish an app. You use the same number for both stores. (Free. Through Apple’s lookup tool a new number takes about 5 business days; requesting directly from Dun & Bradstreet can take up to 30 days — so start here first.)

Check whether you already have one

Many companies were assigned a D-U-N-S years ago without realizing it, so look yours up before requesting a new one:

1. Open Apple's D-U-N-S lookup tool (sign in with your Apple Account). It's free and the fastest route for app publishing.
2. Enter your legal entity name and address.
3. If a match appears, that's your number — you're done. If nothing matches, request a new one in the same flow.

Request a new one (free)

If the lookup doesn’t find your company, request a new number for free right there in the same flow. We highly recommend requesting your D-U-N-S number through Apple’s lookup tool — not directly from Dun & Bradstreet’s website, which is slower and easier to get wrong. You’ll provide:

• Your legal entity name (exactly as registered)
• Your headquarters and mailing address
• A work contact (name, phone, email)

Dun & Bradstreet may call or email to confirm details about your company, so have your registration documents handy. Through Apple’s tool, processing typically takes up to 5 business days, plus up to 2 more for the number to sync to Apple. Requesting directly from Dun & Bradstreet can take up to 30 days.

Once you have it

Keep your number handy — you'll enter the same one when you set up both your Apple Developer and Google Play accounts. Share it with us too, so we can track your setup.

Troubleshooting

• The lookup can't find my company. You probably entered a trading name. Use your exact registered legal name and address. If it still isn't found, request a new number in the same flow.
• It says we're a sole proprietor or not a company. Your business may be registered as a sole proprietorship rather than a company. Contact Dun & Bradstreet to confirm or update your legal status — or reach out to us and we'll help you figure out the right path.
• I just received my number but Apple or Google can’t find it. Newly issued numbers take a day or two to propagate to the lookup systems — wait 48 hours and try again.
• It's taking a long time. Through Apple's tool, your number should arrive within about 5 business days — if it's been more than two weeks, email Dun & Bradstreet. They also sell a paid expedited option, though most companies don't need it. Requests made directly at dnb.com can take up to 30 days; D&B sells a paid expedited option (about USD 229) for that route, but it won't speed up requests made through Apple's tool, and most companies never need it.
