To determine whether your facility has a D-U-N-S® Number already or you need to obtain one, please use the D&B iUpdate service. iUpdate is Dun & Bradstreet's Internet-based service that allows business principals to view, print, and request updates for their company information. iUpdate also has a search function that allows you to search for and obtain the D-U-N-S® Numbers of your business location(s).
If your location is already in Dun & Bradstreet’s database, it will appear here. Select your establishment from the list and follow the on-screen instructions to register in iUpdate. You will be asked a series of questions to confirm your own identity and your connection to the company whose records you are accessing. Please note that Dun & Bradstreet does not own, collect, or store your personal data; Dun & Bradstreet uses commercially available individual identity matching technology to ensure that your identity is not being used fraudulently. Once you are registered in iUpdate, you will be allowed to view your location’s D-U-N-S® Number and access and update your business’s information.
If your business did not appear in the list of search results, first check the information you entered into the search. If this information is correct and your business still does not appear in the results field, your establishment is missing from Dun & Bradstreet’s database. Click on the “Get a D-U-N-S® Number” arrow in the bottom left-hand corner of the page and follow the on-screen instructions. You will need the following information to obtain a D-U-N-S® Number:
