To update the address on your D-U-N-S Number, sign in to Dun & Bradstreet’s Digital Service Center at service.dnb.com, open your company record, edit the address field, and upload two documents that show your legal business name at the new location. D&B typically processes the change within five business days, after which the new address propagates through its global database and shows up on any credit report a lender or supplier pulls on your business.1Dun & Bradstreet. Digital Service Center
Gather Two Supporting Documents First
The most common reason an address update stalls is paperwork. D&B requires two documents, and each one has to display your legal business name exactly as it appears in your D&B profile, along with the new physical address. Personal documents such as driver’s licenses, passports, and bank statements are not accepted.2U.S. Department of Agriculture. D&B D-U-N-S Support for USDA PRS Grant Program – Required Documents
Any two of the following will work:
- A utility bill for electric, water, phone, or internet service showing the business name and new address
- A signed lease for the new location
- The IRS confirmation letter for your Taxpayer Identification Number or Employer Identification Number
- A third-party vendor invoice addressed to your business at the new location
- Homeowners, renters, or commercial insurance documentation reflecting the new address
- A city or state tax permit listing the current address
Sole proprietors need to pay attention to the name-match rule. The documents must show your full legal name unless the DBA is what’s on file with D&B. Save each document as a digital file before you begin, because the portal only accepts electronic uploads.2U.S. Department of Agriculture.

Submit the Change in the Digital Service Center
D&B’s self-service portal for company data changes is the Digital Service Center at service.dnb.com. Older references to “DUNS Manager” and “MyD&B” point to the same function, but the Digital Service Center is the current tool.1Dun & Bradstreet. Digital Service Center
On the portal, choose the option to update an existing D-U-N-S Number. Enter your nine-digit number to pull up your record, or search by legal business name if you don’t have the number handy. After you verify your identity, your current profile fields will appear.
Check the box next to the address field to unlock it for editing, then enter the full new street address, including any suite or floor number. Precision matters, because D&B may cross-reference your entry against postal databases to confirm the location exists. Update the city, state, and ZIP code as well. While you’re in the portal, confirm that the phone number and email on file are current, since D&B uses them to reach you during the review. Upload your two supporting documents and submit.3U.S. Department of Agriculture. D&B D-U-N-S Support for USDA PRS Grant Program – Modification Request
Processing Time and How to Confirm the Change
D&B allows up to five business days to process an address change. If reviewers need clarification or additional documentation, they’ll reach out through the email address or phone number in your request.3U.S. Department of Agriculture. D&B D-U-N-S Support for USDA PRS Grant Program – Modification Request
Log back into the Digital Service Center after five business days and check that your public-facing profile reflects the new address. If it still shows the old location, call D&B customer service at 800-234-3867 to sort out what’s holding up the change.
If You’re Updating Because of a Federal Contract
The federal government stopped using D-U-N-S Numbers on April 4, 2022 and moved entirely to the Unique Entity Identifier assigned through SAM.gov. The two systems are independent, so updating your D&B profile does not update SAM.gov, and updating SAM.gov does not update D&B.4SAM.gov. Entity Registration
If a federal award is the reason you’re changing your address, log in to SAM.gov and edit your registration through the Entity Workspace. You can make address changes at any time. Because SAM.gov registrations must be renewed every 365 days to stay active, it’s worth checking your renewal date and handling both at once if the renewal is close. Entities with only a Unique Entity ID rather than a full registration have less on file — just legal business name and physical address — so the update is shorter.4SAM.gov. Entity Registration
Other Records to Update at the Same Time
Changing your D&B address handles the commercial credit side. A few other records will get out of sync if you don’t touch them.
IRS Form 8822-B
File Form 8822-B to report a business address change to the IRS. It applies to any entity with an Employer Identification Number, active or not.5Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party There’s no statutory deadline for a straightforward address change, but filing quickly keeps IRS correspondence from routing to your old location and causing missed-notice problems. If the move also involves a change in the responsible party — the person who controls the entity’s funds — the IRS requires that specific change to be reported within 60 days. The form’s instructions tell you which IRS service center to mail it to based on your old address.6Internal Revenue Service. Form 8822-B, Change of Address or Responsible Party
Your State Secretary of State
Most states require an amendment or statement of change when a company’s principal address or registered office moves. The form, fee, and timing vary by state and entity type; fees for address amendments generally run from nothing up to around $60. Check your state’s Secretary of State website for the correct form.
A recently filed Secretary of State amendment is also one of the stronger documents to use for the D&B upload, since it carries government authentication that a utility bill doesn’t.
