DUNS Number in Singapore: Lookup, Registration, and Guide
Singapore's position as a global business hub means its companies routinely engage in international trade, cross-border partnerships, and global procurement. A DUNS number is one of the most important business identifiers for Singaporean companies operating beyond domestic borders. This guide explains what a DUNS number is, how to look one up for free, how Singapore's business registration system compares to DUNS, and how to obtain one.
What Is a DUNS Number?
The DUNS (Data Universal Numbering System) number is a unique nine-digit identifier assigned by Dun & Bradstreet (D&B) to individual business entities worldwide. D&B maintains a global database of over 500 million business records across more than 200 countries, and the DUNS number serves as the primary key for accessing information on any given business.
For Singapore businesses, the DUNS number functions as a globally recognized credential that complements your domestic UEN. It is used for credit reporting, supplier verification, government procurement eligibility, and international trade facilitation.
Why Singapore Businesses Need a DUNS Number
Singapore's open, trade-dependent economy creates multiple scenarios where a DUNS number becomes necessary:
International Supply Chains
Singapore is a major trading hub and logistics center. Companies in manufacturing, shipping, electronics, petrochemicals, and professional services frequently work with multinational partners who require DUNS numbers for supplier qualification. Global corporations use D&B data to assess creditworthiness and verify the legitimacy of their supply chain partners.
U.S. Federal Contracts and Grants
Singapore companies bidding on U.S. government contracts or receiving U.S. federal grants must register on SAM.gov, which requires a DUNS number. This is relevant for Singapore's defence industry, technology sector, and research institutions that collaborate with U.S. agencies.
Financial Sector Requirements
Singapore's financial sector, regulated by the Monetary Authority of Singapore (MAS), involves extensive cross-border transactions. Banks, fintech companies, and financial services firms often need DUNS numbers for correspondent banking relationships, regulatory filings, and compliance with international anti-money laundering (AML) frameworks that reference D&B data.
App Store and Platform Registration
Singapore-based app developers registering for Apple Developer accounts or publishing on major platforms need a DUNS number for organizational verification. Given Singapore's thriving tech startup ecosystem, this is a common requirement.
Building International Business Credit
A DUNS number links your Singapore business to a D&B credit profile visible to international partners, lenders, and customers. This is valuable because Singapore domestic credit data (from sources like the Credit Bureau Singapore) is not accessible to overseas parties. Your D&B profile provides a standardized, internationally recognized credit assessment. Learn more about DUNS and business credit.

UEN vs DUNS Number
Singapore businesses are assigned a Unique Entity Number (UEN) upon registration with ACRA or other government agencies. Here is how it compares to a DUNS number.
| Feature | UEN (Unique Entity Number) | DUNS Number |
|---|---|---|
| Issued By | ACRA / Government agencies | Dun & Bradstreet (private) |
| Legal Basis | ACRA Act, various Singapore laws | Voluntary commercial standard |
| Format | 9-10 character alphanumeric | 9-digit numeric |
| Mandatory | Yes, for all registered entities | No, but often required in practice |
| Primary Purpose | Government dealings, tax, regulatory | Credit reporting, international trade, procurement |
| Geographic Scope | Singapore only | Global (200+ countries) |
| Cost | Included with business registration | Free (basic DUNS number) |
| Information Held | Entity name, type, status, registered address | Credit score, payment history, financials, corporate structure |
| Public Access | Via BizFile+ (some data free) | Basic info free; detailed reports paid |
| Credit Profile | No | Yes |
Key distinctions:
- Your UEN is mandatory for all Singapore-registered entities, including companies, sole proprietorships, partnerships, LLPs, and societies.
- A DUNS number is not legally required but is practically essential for international business, U.S. government contracts, and global credit visibility.
- D&B uses ACRA data to build Singapore business records, so your UEN is typically linked to your DUNS profile.
- They serve different audiences: the UEN identifies you to Singapore government agencies; the DUNS number identifies you to the global commercial ecosystem.
MAS and Financial Sector Requirements
The Monetary Authority of Singapore (MAS) oversees banks, insurers, capital markets, and financial advisors in Singapore. While MAS does not directly mandate DUNS numbers, they are relevant to the financial sector in several ways:
Correspondent Banking
Singapore banks maintaining correspondent banking relationships with international banks (especially U.S. banks) often need DUNS numbers. International correspondent banks use D&B data as part of their Know Your Customer (KYC) and due diligence processes.
Fintech and Payment Institutions
Singapore's growing fintech sector, operating under MAS licensing frameworks (such as the Payment Services Act), frequently needs DUNS numbers when establishing partnerships with international payment networks, card schemes, or banking partners that require D&B verification.
Regulatory Filings
Some international regulatory frameworks and cross-border reporting standards reference DUNS numbers as business identifiers. Singapore financial institutions participating in international regulatory cooperation may encounter DUNS requirements in foreign jurisdictions.
How to Get a DUNS Number in Singapore
If your lookup shows that your business does not yet have a DUNS number, follow these steps. For a general overview, see our complete guide to getting a DUNS number.
Step 1: Prepare Your Business Information
Gather the following before applying:
- Registered company name as filed with ACRA
- UEN (Unique Entity Number)
- Registered address and principal place of business
- Entity type (Private Limited, Sole Proprietorship, Partnership, LLP, etc.)
- SSIC code (Singapore Standard Industrial Classification) or business activity description
- Date of incorporation or registration
- Number of employees
- Annual revenue (approximate figures acceptable)
- Name and contact details of a director or authorized representative
- GST registration number if applicable
Step 2: Submit Your Application
Contact D&B Singapore or apply through the D&B website. Singapore falls under D&B's Asia-Pacific operations.
- Free application: Standard processing takes approximately 30 business days. D&B may contact you for verification.
- Expedited application: Paid options are available for faster processing, typically within 1-5 business days. Contact D&B for current pricing.
Step 3: Verification
D&B will verify your business information against ACRA records, public filings, and other data sources. They may contact you by phone or email to confirm details. Respond promptly to avoid delays.
Step 4: Receive and Review Your DUNS Number
Once assigned, your DUNS number is permanent. Review your D&B profile for accuracy, paying attention to:
- Legal entity name and type
- Registered and operating addresses
- Industry classification
- Corporate family tree (parent/subsidiary relationships, especially important for Singapore holding companies with regional subsidiaries)
- Financial information
Step 5: Maintain Your Record
Update D&B after significant business changes such as director appointments, address changes, corporate restructuring, or significant revenue changes.
Cross-Border Trade: ASEAN and Beyond
Singapore serves as a gateway to Southeast Asia, and a DUNS number supports cross-border trade across the ASEAN region and globally.
ASEAN Trade
Singapore companies operating across ASEAN member states (Malaysia, Indonesia, Thailand, Vietnam, Philippines, etc.) benefit from having a DUNS number because:
- Supplier qualification: Regional partners and multinationals operating in ASEAN use D&B data for supplier vetting.
- Standardized identification: Each ASEAN country has its own business registration system. The DUNS number provides a consistent identifier across all of them.
- Regional credit visibility: D&B maintains databases covering all ASEAN markets, and your Singapore DUNS number links to a credit profile visible across the region.
Regional Headquarters
Many multinational corporations use Singapore as their Asia-Pacific or ASEAN regional headquarters. These entities typically need DUNS numbers for their Singapore holding company, and separate DUNS numbers for subsidiaries in each country of operation. D&B links these in a global corporate family tree.
Free Trade Agreements
Singapore has one of the most extensive networks of Free Trade Agreements (FTAs) globally. While FTAs do not require DUNS numbers, the cross-border trade they facilitate often involves supplier verification processes where D&B data and DUNS numbers are referenced.
