Good tracking starts with keeping all parcel information in one place. Record the order date, tracking number, carrier, destination country, and the last visible update.
Common tracking stages include label created, carrier received package, departed origin facility, customs processing, arrived in destination country, out for delivery, and delivered. Different carriers use different wording, but the flow is usually similar.
If the tracking page is quiet, check whether the carrier is known for delayed scans. Some international lines provide limited updates until the parcel reaches the destination country.
If nothing changes for a long period, use your order record to contact support with specific details. A clear tracking log is much more useful than a vague message saying the parcel has not arrived.
