UPIK® ("Unique Partner Identification Key") is an online platform that supports the search of the D&B D-U-N-S Number for your own company, as well as the application process for the allocation of a D&B D-U-N-S Number. The D&B D-U-N-S Number is a unique identifier. It is based on an identification number system developed by Dun &Bradstreet Inc., with numbers assigned to companies and similar economic factors (companies within the meaning of §14 of the German Civil Code (BGB)). D&B D-U-N-S Numbers serve the purpose of simplifying the dialogue and traceability of business partners in national and international financial transactions, particularly in the context of preparing for and implementing business relationships. The UPIK platform can be used to apply for D&B D-U-N-S Numbers, manage the corresponding user data and determine the names or D&B D-U-N-S Numbers of other economic actors via a search function. The provider of the UPIK website and the user’s contract partner for services relating to the UPIK online platform is Dun & Bradstreet Deutschland GmbH,Brüsseler Straße 1-3, 60327 Frankfurt am Main (“D&B”).

Obtaining and using your own D&B D-U-N-S Number for your business comes at no cost. However, if you require expedited processing or if your request concerns a business outside of Germany, there may be an associated cost. You will be notified of any charges in advance.
