A courier gave me only a tracking number. How do I find which order it belongs to?

The search box in Orders → Manage Orders doesn't look at tracking numbers. Use the shipping report instead:

1. Go to Analytics → Reports and open Shipping labels by order. You can type it into Search reports….
2. Set the date range to cover when the order was placed. The report filters by order date, not ship date.
3. The table lists Order ID, Shipping carrier and Tracking number for every order with a saved tracking number. Look for the AWB there, or click Export CSV and search the file.
4. Copy the order ID into the search on Orders → Manage Orders to open the order.

Only orders whose carrier and tracking number were saved in the order's Fulfilment & Tracking box appear in this report.
