Hello @Nemores 

Try this 

1. Go to your Shopify admin and click on Orders.
2. In the Orders page, click on the Filter button.
3. In the Filter dialog, select the Customer filter and enter the phone number of the customer that you want to find.
4. Click on the Apply button.
5. This will filter the orders to only show orders that were placed by the customer with the phone number that you entered.
6. You can then count the number of orders that are displayed.
