How to delete a tracking number

Tracking numbers must be removed from any active call flow before they can be deleted. Follow both sections below in order.

Before you delete: understanding the tracking number lifecycle

When you delete a tracking number, the following happens:

• The number is released back to the carrier and becomes available to other users. It cannot be recovered or re-assigned to your account.
• All historical call data attributed to that number remains in your account. Deleting the number does not delete its call history.
• Any active call flow that included the number must be updated before deletion. Calls to a number with no assigned flow will not route.
• If the number was part of a DNI pool, the pool shrinks, which may affect attribution accuracy. Consider replacing the number rather than removing it.
• Workflows triggered by calls to that number will continue to exist but will no longer fire on it.

If you want to temporarily stop using a number without losing it, removing it from its call flow (without deleting the number itself) is a safer option.

Step 1. Remove the tracking number from its call flow

• Go to Tracking > Call Flows and open the call flow linked to the number you want to delete.

Remove the tracking number from the call flow by doing one of the following:

• Reassign the 'Dial' action to a different tracking number.
• Delete the call flow section associated with this number.
• Delete the entire call flow if it's no longer needed.

Step 2. Delete the tracking number

• Go to Tracking > Numbers and locate the tracking number.
• Click the 'x' icon next to the call flow name on the far right to release any remaining assignment.
• Select the number, click the bin icon, then click 'Remove' on the confirmation message.

🎉 That's it! You will receive a confirmation notification once the tracking number has been successfully deleted.
