Manage My D&B D-U-N-S® Profile

Are you sure that you are being evaluated based on the latest, most accurate information on your business?

A critical step in building and managing good credit is to proactively keep your D&B credit file up to date. An accurate credit file can help you promote your company in the best light possible.

D&B's iUpdate is an online tool which makes it fast and easy for you to review and update your credit file. Use iUpdate to notify D&B of important changes to your business and ensure that your D&B credit file is the most up-to-date it can be.

Authorized company representatives can update their company information using iUpdate or by contacting our Customer Service Center at (888) 814-1435, Monday through Friday, 8:00AM - 6:00PM local time or custserv@dnb.com.
