# Managing Duplicates
### Video Guide
## What are duplicates
Duplicates are two or more customer profiles that the portal flags as belonging to the same individual. The portal automatically looks for matching data points, such as:
* Document ID and date of birth
* Date of birth and family (last) name
Resolving duplicates prevents:
* Inaccurate reporting and analytics
* Double-handling of onboarding reviews
* Compliance risks linked to multiple identities for one person
If duplicates are not yet enabled in your workspace, contact FrankieOne Support to switch the feature on.
## Where to find Duplicates
1. Sign in to FrankieOne Portal v2.
2. Open **Profiles › Entities**.
3. Look for the **Duplicate** badge in the **Onboarding Summary** column.
4. Select the customer row to open the profile.
5. In the profile header, choose the **Duplicates** tab to view side-by-side comparisons of the potential match.
You need the “Show duplicate page” and “Fetch duplicate entities” permissions to view this tab. Team admins can assign these in **Settings › Users › Roles**.
## How to resolve duplicates
| Action | Result |
| :---------------------- | :------------------------------------------------------------------------------------------------ |
| Mark **True Positive** | Confirms the profiles belong to the same person. The duplicate record is blocked from onboarding. |
| Mark **False Positive** | Confirms the profiles are different people. Both records remain active. |
Follow these steps:
1. In the **Duplicates** tab, review the side-by-side data (name, document IDs, addresses, dates of birth).
2. Select **Change match status**.
3. Choose **True Positive** or **False Positive**.
4. Add a short explanatory comment—this is stored in the audit log.
5. Confirm.
After a **True Positive** decision, only the primary profile stays active. After a **False Positive** decision, the duplicate flag is cleared and no further action is required.
## FAQ
**Why did the portal miss a duplicate?** The match engine relies on the data you collect. Typos or missing fields can stop automatic detection. Edit the profile and re-run checks if needed.
**Can I customise the matching rules?** Yes. Contact Support to request additional or different matching criteria (for example, email + phone).
**Who can resolve duplicates?** Any user role that includes the “Set entity as duplicated” permission.
