# How do I update my company’s DUNS number?

## Symptom

How do I update my company’s DUNS (Data Universal Numbering System) number in SAP Business Network?

## Cause

The DUNS Number is an identification code that only applies to companies registered in the US. It is stored in your **Company Profile**.

If your company does not have any DUNS Number, you must not enter one as it is not mandatory.

## Resolution

SAP Business Network is integrated with Dun & Bradstreet and can automatically identify your company’s DUNS number.

If a match is found, you will receive a notification in your profile.  
Click the notification to access **Edit Company Information**.  
Review the details and select one of the following options:

- **Accept**
- **Reject**

Updating the DUNS number manually

If needed, you can update the number manually:

1. Click **\[your initials\] > Company Profile**
2. Click the edit icon next to the company name
3. Update the **DUNS Number** field
4. If you do not know the number, click **Don’t know your DUNS number?**
5. Click **Save**
