My Tracking Number Isn't Working

Troubeshooting steps for tracking numbers that aren't working.

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:

After manually selecting the correct carrier

How do I manually select the correct carrier on 17track.net?

Same tracking code, very different result. Here's how to do it:

1. Navigate to www.17track.net

2. Enter your tracking code into the orange tracking box

3. Instead of just clicking "Track", instead, click where it says "Carrier (Auto-Select)"

4. When you click "Carrier (Auto-Select)", you'll see a list of options to select. Identify which carrier corresponds with the tracking code you are looking up by looking at the list below, then manually search for that carrier, and select it.

5. Once you've manually selected the correct carrier, then hit "TRACK", and you should see the detailed tracking information appear.

If tracking remains unavailable for more than three business days after the first scan, use Order Issues in your Zendrop dashboard to flag the order, the fulfillment team will follow up directly in the issue thread.

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, head to the Order Issues tab in your Zendrop dashboard, find the order, and submit a flag. The fulfillment team reviews it there and replies directly in the issue thread, don't use the chat messenger for this.

  • 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.
