A D-U-N-S Number can help businesses establish their identity when dealing with platforms, suppliers, lenders, partners and other organizations.

📈 D-U-N-S Number Use Cases

🔢 How Does a D-U-N-S Number Work?

A D-U-N-S Number identifies a business entity on a location-specific basis. Apple specifically describes it as a unique nine-digit number used to verify an organization's identity and legal-entity status.

Example

Business Name: ABC Technologies Private Limited
D-U-N-S Number: 12-345-6789 (illustrative example only)

The actual number is assigned by D&B.

🧾 Documents & Information Generally Required

When requesting or verifying a D-U-N-S Number, you may need accurate business information such as:

Apple states that organizations may be asked for the legal entity name, headquarters address, mailing address and work contact information when looking up or requesting a D-U-N-S Number.

🛠️ How to Get a D-U-N-S Number

Step 1️⃣ — Check Whether Your Business Already Has One

Before requesting a new number, search for your organization in the D&B database.

Make sure your:

• Legal name

• Address

• Contact information

• Business registration details

match your official business documents.

Step 3️⃣ — Submit the Request

If your business is not already listed, submit the required information to D&B.

Step 4️⃣ — Business Verification

D&B may contact the business representative to verify information.

Keep your incorporation and business documents available.

Step 5️⃣ — Receive Your D-U-N-S Number

Once assigned, you'll receive the unique nine-digit identifier.

For Apple enrollment, Apple currently advises allowing up to five business days for D&B to provide the number, followed by up to two business days for Apple to receive updated information from D&B.
