What Is a D-U-N-S Number? Uses for Your Business

A D-U-N-S Number is a nine-digit identifier assigned by Dun & Bradstreet to a business record. It helps organizations identify the business they are dealing with.

Published by MASTERSTAP · Updated 12 September 2026

What can the number help with?

A customer or platform may use the identifier to locate business information during verification. Ask the organization requesting it what information must match and what additional evidence it needs.

What does the number not prove?

It is not a credit score, a government incorporation certificate or a guarantee of platform approval. Having an identifier does not promise funding, customers or an international contract.

How should you prepare?

Make a short record of your legal company name, country, business address and intended use. If you have an existing number, include it when requesting assistance. Compare details before beginning another request.

Use the application readiness checklist.

Frequently asked questions

What is a D-U-N-S Number?

A D-U-N-S Number is a nine-digit business identifier assigned by Dun & Bradstreet. It identifies a business record; it is not an app-publishing approval or a credit score.

Does a D-U-N-S Number guarantee Google or Apple approval?

No. Google and Apple independently verify eligibility and other account requirements. A D-U-N-S Number is one part of organization verification.

Does a D-U-N-S Number guarantee international customers?

No. Business identification can support a buyer’s checks, but contracts depend on the buyer’s requirements and assessment. A number is not a promise of sales or finance.
