Where does my customer see the courier and tracking number for their order?

Customers see it in their account on your store. Once they're signed in, they open My Orders from the account menu and pick the order. The Fulfilment & Tracking section shows:

• Carrier, the courier you chose
• Tracking number, the AWB you entered
• Tracking status, if the courier has reported one

The order list in My Orders also shows a short "Shipped via" line with the courier and tracking number.

Before the order ships, that section says tracking details will appear once it's on the way. Guest shoppers can use the Track your order page on your store (your store address followed by /track). They enter their order number and the email they used at checkout to see the courier and tracking number.
