Step 3: Get Your DUNS Number

Data Universal Numbering System (DUNS)

Assignment of a D-U-N-S® number is free for all entities required to register with the federal government by a regulatory agency.  This includes federal contractors, prospective government vendors and applicants and recipients of federal grants.  The D-U-N-S® number is a unique nine-digit identification code and is issued by Dun & Bradstreet (D&B).  It remains with the company location to which it has been assigned even if it closes or goes out of business.


Click here to request your D-U-N-S Number via the Web. If one does not exist for your business location, it can be created within 1 business day.

Online, go to iUpdate and start by making sure you do not already have a DUNS number, and then provide the requested information about your business or organization. Within 24-48 hours, you will receive your D-U-N-S® Number via email.

You will need to provide the following data elements to obtain a D-U-N-S® Number:

  • Legal Name
  • Doing Business As (DBA), or other name by which your organization is commonly
  • Physical Address, City, State and Zip Code
  • Mailing Address (if separate)
  • Telephone Number
  • Contact Name
  • NAICS Code (Line of Business)
  • Number of Employees at your location
  • Headquarters name and address (if there is a reporting relationship to a parent
    corporate entity)
  • Annual Revenue
  • Number of Employees
