# Replacing an order's old tracking number with a new tracking number
If you receive a new tracking number from your supplier or fulfillment service, you can follow these steps so that Tracktor can display new tracking information based on the new tracking number.
1\. Starting from your Shopify admin dashboard, navigate to the **Orders** page.
2\. Navigate to an order that needs to be updated with the new tracking number.

{% endhint %}
3\. Click on the three-dot icon and then **Edit tracking**.
4\. Paste the new tracking number into the **Tracking number** field and click **Save**. You can unselect the checkbox if you do not want to notify your customer that their order has been updated.
