# We found existing accounts based on the information you entered. Please review.

## Symptom

When trying to create a new account through an invitation email sent by the buyer or self-registration from the Supplier Registration Portal, the below warning message appears:

We found existing accounts based on the information you entered. Please review.

## Cause

When registering a new account on SAP Business Network, the system automatically checks for:

- Company name
- Company email domain
- DUNS number
- Other identifiers linked to your company

If matches are found, you’ll get a warning message like:

We found existing accounts matching your company details. Please review them before proceeding.

## Resolution

To check for accounts you or someone in your company may have already registered, follow these steps:

1. Click **Review accounts** in the pop-up warning message.
2. Review the matched account. You can view the details of each account from **Top recommendations** and **Other existing accounts** list.

- If you find an existing account that you want to use, click **Contact administrator** to send a message to the account administrator requesting access. Then click **Send email**.  
  Once the administrator of the existing account adds you as a user, you will be able to log in through the invitation using that account.
- If none of the displayed accounts are relevant, click **Back** > **Continue account creation** to create a new account. Once the account is created and you have signed in, you will be linked to the buyer and any documents / events they have sent you.

## See Also

- The email to the account administrator will be sent from ordersender-prod@ansmtp.ariba.com
- SAP cannot provide specific account information, such as email address or administrator details. The best way to find out who registered other existing accounts is to send an email to the administrator directly via **Contact administrator** button.
