How to Verify a Company's DUNS Number Online
Whether you want to find your own DUNS number or verify that of a potential business partner, several methods are available. This guide explains how to perform this verification effectively and what you can learn from it.
Why Verify a Company's DUNS Number?
Verifying a company's DUNS number serves several distinct purposes depending on the situation:
Due diligence before partnership
Before signing a contract or entering a significant business relationship, verifying a partner's DUNS confirms their legal existence and provides access to basic financial information.
Supplier verification
As part of a supplier approval policy, many large companies require their suppliers to have a valid, up-to-date DUNS number.
Know your own DUNS
If you're unsure whether your company already has a DUNS number (automatically assigned by D&B), the first step is to verify this before requesting a new one.
Form validation
Some tenders or registration forms require DUNS verification to ensure the number provided is indeed associated with the applicant entity.
Method 1: DUNS Verify (Fast and Simple)
The simplest way to verify a DUNS number is to use the DUNS Verify service. By entering the company name and city, our system automatically searches the D&B database and returns the associated DUNS number by email in under 2 minutes.
This service is particularly useful if you want to:
- Find out your own DUNS number before starting a process
- Quickly verify that a company has a DUNS number
- Obtain a DUNS number if the company doesn't have one yet

Dun & Bradstreet offers several online tools for researching company information. The main portal allows you to search by company name, city, and country to find entities registered in the D&B database.
Accessing detailed information about a company (financial data, credit scores, history) generally requires subscribing to one of D&B's paid plans. Simply verifying the existence of a DUNS number is often available for free.
Method 3: Local D&B Partners
In many countries, D&B works with official local partners who can help search for and verify DUNS numbers. These partners often have comprehensive knowledge of local business data, making them particularly valuable for verifying companies in specific markets.
These local portals are often a good source of information for domestic companies, as they combine local registry data with D&B's international database.
What the DUNS Number Reveals About a Company
The DUNS number itself is an identifier — it's what it gives access to that's truly valuable. Here's what you can obtain through a company's D&B profile:
Basic information
- Official company name
- Registered address
- Legal structure
- Date of incorporation
- Industry / activity code
Structural information
- Approximate headcount
- Group structure (parent company, subsidiaries)
- Declared turnover (if public)
- Key executives
Financial information (subscription required)
- Paydex score (payment behavior)
- D&B credit score
- Recommended credit limit
- Payment incident history
How to Interpret a DUNS Number
The DUNS number itself (9 digits) contains no encoded information about the company — unlike some national identifiers. The DUNS is purely sequential: numbers are assigned in order of registration, with no information embedded in the digits themselves.
What matters is verifying that the DUNS number you're given actually corresponds to the right company. Fraud cases do exist where companies use another entity's DUNS number. Verification therefore means ensuring the DUNS number is correctly associated with the company name, address, and information in question.
Concrete Use Cases
Verification Before Signing a Contract
A distribution company receives an offer from a new foreign supplier. Before signing, they verify the supplier's DUNS to confirm legal existence and consult their credit score. The result: the supplier has a Paydex score of 80/100, indicating generally on-time payments.
International Tender
A public procurement officer verifies the DUNS of several tender applicants to ensure the numbers provided correspond to the actual candidate companies. Two applicants submit invalid DUNS numbers and are immediately disqualified.
