Before You Delete a WhatsApp Phone Number
Deleting a phone number can remove access to information associated with that number. Meta's deletion confirmation indicates that you can lose access to:
The display name and profile.
Official business status, when applicable.
Messaging limit tier and quality rating.
Chat history and insights data.
Meta also indicates that migrating the number to another WhatsApp Business account may preserve some account information, but chat history and insights data are not preserved through that migration. Only continue with deletion when you are certain the number should be removed.
How to Delete a WhatsApp Phone Number
Step 1: Start the deletion from Kyrios
In Kyrios, go to Settings.
Select WhatsApp.
Open the Numbers tab.
Find the phone number you want to remove.
Select the three-dot menu in the Actions column.
Select Delete number.
This starts the deletion process for the selected WhatsApp phone number.
Step 2: Select the phone number in Meta WhatsApp Manager
The deletion process continues in Meta WhatsApp Manager.
Open Phone numbers if it is not already displayed.
Locate the phone number you want to delete.
Select the trash icon beside the phone number.
Make sure you select the correct phone number before continuing.
Step 3: Review the deletion warning
Meta displays a Delete phone number confirmation window describing what will be lost when the number is deleted. Review the warning carefully. If you want to continue, select Next.
Selecting Next does not complete the deletion. An additional security confirmation is required.
Step 4: Enter your password and delete the number
Meta requires the password used to access the connected WhatsApp Business account before the deletion can be completed.
Enter your password.
Optionally select a Reason for deletion.
Select Delete.
The deletion cannot be undone through this confirmation process.
What Happens After the Phone Number Is Deleted
After the deletion is completed, the phone number is removed from its existing WhatsApp connection. The deleted number can no longer be used through that connection to send or receive WhatsApp messages. Information associated with the number may also become unavailable, including its display name and profile, business status, messaging limit and quality information, and chat history or insights data.

Password confirmation is part of Meta's security process for deleting a WhatsApp phone number. Enter the password used to access the connected WhatsApp Business account before continuing.
The Delete button is not available yet
Complete the required password field before attempting to select Delete.
If Meta presents additional required information or validation, complete those requirements before continuing.
