What Is a DUNS Number and Why Does It Matter for Companies Going Global

A DUNS Number (Data Universal Numbering System) is a nine-digit, globally unique identifier assigned to businesses by Dun & Bradstreet, a US-based company. In use since 1963, the system is widely used for verifying commercial information and identifying businesses worldwide, and is recognized as a standard business identifier by numerous international institutions and platforms. For companies going global, a DUNS number matters in several ways. First, it helps establish a business credit history. Dun & Bradstreet compiles a credit report by aggregating information such as a company's financial standing, years in operation, and payment history — a report frequently used by overseas partners, suppliers, and financial institutions as a reference point when assessing a company's credibility. Without a DUNS number, a company is effectively invisible within the international business credit system, which can slow down potential partners' efforts to verify its background. Second, some platforms and institutions require a DUNS number as a prerequisite for access or partnership. For example, registering certain app store developer accounts, bidding on government procurement projects, and onboarding to international supply chain platforms may explicitly require a valid DUNS number as part of identity verification. Third, a DUNS number can help build credibility in international business dealings. For companies that have just entered an overseas market and haven't yet established brand recognition, having a searchable D&B profile can lower the trust barrier for potential partners to some degree. The general process for obtaining a DUNS number involves submitting basic company information — such as company name, registered address, date of establishment, and contact details — through Dun & Bradstreet's official website or an authorized channel. After review, Dun & Bradstreet assigns a number and creates a business profile. Standard applications are typically free, though processing can take several weeks; expedited processing may be available for a fee through official or authorized channels.
