Request Data

Each year, hundreds of organizations request or engage their suppliers, portfolios, and other stakeholders to report key environmental data, by disclosing through CDP.

These requesters can include: 

  • CDP Supply Chain members, typically large purchasing organizations looking to future-proof their supply chains;  

  • Membership/initiatives such as RE100; 

  • Private Markets requesters (ie asset owners and fund managers with private market portfolios); and 

  • Banks providing supply chain financing solutions to their corporate customers.

   

Requesters use this data to inform decisions and drive environmental action.

Improving the request process with Dun & Bradstreet: Using unique identifiers

To ensure these requests reach the right organization and that we build the most accurate and comprehensive database of environmental information, CDP is working with the Dun & Bradstreet database of over 500 million companies and using DUNS numbers as a unique identifier.

Every company in the CDP database is identified with a unique Data Universal Numbering System (DUNS) number, provided by Dun & Bradstreet. Please note that cities, states and regions, and some other organizations are not assigned DUNS numbers.

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.

Cities, states and regions do not need DUNS numbers.

Learn more about resolving issues with 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 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.

If the extended search comes back blank, please check our Knowledge Article on resolving issues with DUNS numbers. If you need to raise a ticket with My Support on our Help Center, please raise one case listing all the organizations you cannot find and any that you have queried with Dun & Bradstreet to help us respond to you efficiently.

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. For further information please visit the DUNS website.
