# 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.

|| Once no call flows are assigned to the tracking number, you can proceed with deletion.

### 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.
