# Why Were Two Customers Merged

When Maestra merges two customer profiles into one, it's usually because the system has enough evidence that they belong to the same person. Here are the possible reasons.

## Possible reasons

<Steps>
  <Step title="The customer data matched completely">
    The two profiles shared the same email, phone number, and device.
  </Step>

  <Step title="Consistent data came from the same device">
    Non-conflicting data was entered from one device. For example, a customer first subscribed to web push notifications, then later subscribed to an email campaign from the same browser. Maestra treats this as the same person and merges the profiles.
  </Step>

  <Step title="A merge operation was called">
    The customer merging operation was triggered, and the profiles were force-merged. The higher-priority profile is specified explicitly in the operation call.
  </Step>

  <Step title="Manual merge through the admin panel">
    An operator merged the profiles manually through the web interface of the admin panel.
  </Step>

  <Step title="Customers confirmed the same point of contact">
    Both customers confirmed the same email address or phone number.
  </Step>
</Steps>

<Tip>
  You can find the reason for a merge on the **Change history** tab of the customer profile.
