Request Data

A DUNS number, or Data Universal Numbering System number, is a unique nine-digit identifier assigned to businesses by Dun & Bradstreet, a global data provider. It serves as a universal method of identifying businesses and is widely used in the business world for various purposes, including credit reporting, tracking financial transactions, and facilitating business-to-business transactions.

DUNS numbers are often required for companies seeking to do business with government agencies, applying for grants or contracts, or participating in certain industry-specific programs. They provide a standardized way to uniquely identify and track entities across different systems and databases.

As of the 2024 disclosure cycle, CDP has adopted DUNS numbers as a unique identifier for companies in our database. Having a unique identifier, such as a DUNS number, ensures data integrity, reduces the risk of duplicate entries or discrepancies, and allows for more efficient processes for companies requesting disclosure or responding through CDP. 

Dun & Bradstreet's DUNS number system offers a widely recognized method for identifying entities globally with a database of over 500 million companies, including private companies. We have chosen to use DUNS numbers following a comprehensive review.  

Companies of all sizes can register for a DUNS number from anywhere in the world, making DUNS best suited to meet the needs of the exponential increase in companies using the CDP Portal.

All companies in the CDP database will be identified by a DUNS number. Introducing a unique identifier to our CDP database facilitates efficient, scalable data management. The Dun & Bradstreet database contains over 500 million companies. Most of the organizations disclosing through CDP already have a DUNS number. For organizations where a DUNS number cannot be found, the requester will be able to raise a case through the CDP Portal to have one assigned. 

If you cannot find the correct organization's details or are unable to register for a DUNS number with the Dun & Bradstreet database, please raise a single ticket on CDP's Help Center listing all organizations you cannot find. 

Cities, states and regions don't need DUNS numbers.

You can access your DUNS number through the organization details page of the CDP website if Dun & Bradstreet has registered a DUNS for your organization.

If you do not know your DUNS number, you can get one by registering with Dun & Bradstreet, the organization responsible for issuing DUNS numbers.

The organizations you are requesting to disclose all need to be registered with Dun & Bradstreet. You can find their DUNS number in the CDP Portal. 

Simply use the search and find tool on the CDP Portal to look up organizations you would like to request. You can search using a company's name, country, DUNS number and registered office address. Make sure your spelling is correct and start with the company’s registered office address before trying different names or aliases which the company might be known by. 

If you cannot find the correct company details on the Portal, you can carry out an extended search. If the extended search comes back blank, please raise a ticket on CDP's Help Center listing all the organizations you cannot find. 

If the search provides incorrect details, you must contact Dun & Bradstreet, as only they can correct the source of this information. Please only add information you know is correct for the organization being searched. 

Please raise one case with CDP listing all organizations that are missing DUNS numbers and any that you have queried with Dun & Bradstreet; this will help improve efficiency in responding.

There is no cost to request and receive a DUNS number. However, you can pay a small fee to speed up the process and receive your number more quickly. If you have purchased an expedited DUNS service, you can get your number within eight business days.

The time it takes to receive a DUNS number from Dun & Bradstreet can vary.
