What is D-U-N-S?

D-U-N-S (Data Universal Numbering System) is a unique nine-digit identifier issued by Dun & Bradstreet (D&B) for every business entity or facility worldwide. It is a “key” that enables companies to build a business credit profile, verify legitimacy with partners, and participate in global supply chains.

Key Benefits of Having a D-U-N-S Number

• Business identity verification: Allows partners, banks, and customers to confirm your company’s legitimacy.
• Builds business credit: Helps when applying for credit, negotiating payment terms, or attracting investment.
• Mandatory on some global platforms: For example, Apple Developer Program and large procurement networks often require D-U-N-S.
• Facilitates exports and imports: Recognized worldwide, boosting trust with international organizations.
• FDA Facility Registration: Currently, when registering a facility with the U.S. Food & Drug Administration (FDA) for exporting food, pharmaceuticals, or cosmetics to the U.S., you must have a D-U-N-S number to verify your facility address. Without it, FDA will not validate your registration.

Non-U.S. Companies Can Also Apply

• D&B maintains a global database in over 200 countries, including Vietnam. Any company outside the U.S. can obtain a D-U-N-S number by submitting the proper legal information. Many Vietnamese companies (especially exporters, software developers, Apple Developers) have successfully registered.
• You only need your Vietnamese Tax ID plus legal name, address, phone, email — and optionally a U.S. representative such as UIMEX Vietnam to assist with the process.

Required Information

• Official legal name (Vietnamese and English, if available).
• Business address.
• Vietnamese Tax ID (instead of U.S. EIN).
• Company phone and email.
• Year established and type of business.
• Legal representative’s name.

How to Apply

• Directly via D&B’s official site or via https://www.uimex.vn/duns-number
• Or contact D&B’s local office/representative in Vietnam.
• Basic registration is free (about 30 days); expedited service (paid) can take just a few days.
• Bottom line: D-U-N-S is a global business identifier that enhances your company’s credibility and opens doors to international partnerships. It is now mandatory for FDA facility registration if you plan to export food, pharmaceutical, or cosmetic products to the U.S.
