## **What does this error mean?**

This error appears during WhatsApp onboarding when the phone number you are trying to register is already linked to an existing WhatsApp account. WhatsApp allows a phone number to be active on only one WhatsApp account at a time.

To proceed with onboarding, the number must be fully disconnected from any existing WhatsApp (consumer or business) account.

- What this covers: To proceed with onboarding, the number must be fully disconnected from any existing WhatsApp (consumer or business) account.

## **How to resolve the issue**

#### **Step 1: Remove the number from the existing WhatsApp account**

On the device where the number is currently active:

1.  Open **WhatsApp** or **WhatsApp Business**.
    
2.  Go to **Settings** → **Account**.
    
3.  Select **Delete my account**.
    
4.  Confirm the phone number and complete the deletion.
    

> Important: Simply uninstalling the app is **not sufficient**. The account must be deleted from WhatsApp settings.

#### **Step 2: Wait for WhatsApp to release the number**

After deleting the account:

-   Wait **up to 3 minutes** for WhatsApp to fully release the number.
    
-   In some cases, it may take slightly longer depending on WhatsApp’s systems.

## **If the error still persists**

-   Ensure the number is not active on **any other device**.
    
-   Confirm the number is not tied to another **Meta Business Manager or WhatsApp Business Account**.
    
-   Wait 10–15 minutes and retry if the number was recently deleted.
    
-   If the issue continues, contact support with:
    
    -   Phone number (with country code)
        
    -   Screenshot of the error
        
    -   Business Manager ID (if applicable)

## **Best practices to avoid this error**

-   Always use a **new or unused phone number** for WhatsApp onboarding.
    
-   Avoid reusing numbers that were recently connected to WhatsApp.
    
-   Do not attempt onboarding while the number is still active on any WhatsApp app.
