Sometimes when you look up a tracking code on a tracking site (like 17track.net or parcelsapp.com), the correct carrier is not automatically detected by the tracking site. This can lead to the tracking code you're looking at not showing any updates.
Manually selecting the correct carrier fixes this in most cases. Here are the most common Zendrop carriers and how to select them on 17track.net:

If tracking remains unavailable for more than three business days after shipment confirmation, you can contact Zendrop’s support by providing your order reference for faster assistance.
Resolving tracking information gaps
Gaps in tracking updates are usually caused by one of these:
Freight forwarder updates. Some couriers only scan at major transit points, so gaps between scans are normal.
Recently shipped. Wait up to three business days for the first scan to appear.
Prolonged gaps. If nothing updates after three business days, submit a request through the in-app messenger.
Customs clearance. Packages aren't scanned until they clear customs and reach the next facility.
Carrier suspension. Some destinations experience delays when a carrier temporarily suspends service.
