You click "buy." Then you wait. It's the same cycle every time you order something from halfway across the planet, whether it’s a niche mechanical keyboard from Shenzhen or a vintage leather jacket from a shop in Florence. Tracking says "shipped," and then... nothing. For six days. Honestly, the anxiety of a package sitting in a mysterious warehouse in Liege or Dubai is a universal modern headache.
If you want to know how to track overseas packages effectively, you have to stop relying solely on the link the retailer sent you. Those links are often just "milestone" trackers. They only update when a major event happens, leaving you in the dark for the 4,000 miles in between.
The reality of global logistics is a messy, fragmented web of handoffs. Your package isn't staying with one company. It’s a relay race.
The handoff problem: Why your tracking stops moving
Most people think FedEx or UPS handles everything from door to door. Sometimes they do. But more often, especially with cheaper shipping, your package moves through a "postal injector."
Here is how it actually works. A company like Yanwen or 4PX picks up the parcel in China. They fly it to a hub. Then, they hand it off to a local courier like Pitney Bowes or directly to the USPS once it clears customs. This is where the tracking usually "breaks." The original tracking number might not even work on the new carrier's website. You’re looking at a screen that says "LHR - Arrived at Hub" for a week, wondering if a seagull stole your boots.

The trick is finding the Universal Tracking Number.
Most international shipments have an S10 standard identifier—that’s the two letters, nine digits, and two letters at the end (like RS123456789CN). If you have that, you can usually plug it into the Universal Postal Union (UPU) network. But if you have a "last-mile" tracking number, you need a multi-carrier aggregator. Sites like 17Track, ParcelsApp, or Ship24 are better than the carrier's own site because they "scrape" data from both the origin and destination couriers simultaneously. They see the handoff that the shop’s website ignores.
Customs is the "black hole" of international shipping
Don't panic when a package stays in "Customs Clearance" for four days. That is normal.
Actually, it's more than normal; it's expected. Every single item entering a country must be documented. In the US, Customs and Border Protection (CBP) handles this. They aren't looking for your socks; they are looking for misdeclared values or restricted items. If your package is stuck, it’s rarely because of a problem. It’s usually just volume. During peak seasons like Singles' Day (November 11) or the lead-up to Christmas, the backlog at major ports like JFK or LAX is staggering.

Pro tip: If you see a status like "Held in Customs" for more than 10 days, check your email—including spam. You might owe Import Duties or VAT. In the UK, Royal Mail won't deliver until you pay the "Fee to Pay" card online. In the US, most consumer goods under $800 (the de minimis threshold) pass through duty-free under Section 321, but if you're over that, the package sits until the bill is settled.
How to track overseas packages using secondary data
Sometimes the tracking number just flat-out fails. It happens.
When that occurs, you can often track the container or the flight if you have the right info. This is for the true logistics nerds, but it works. Look at your tracking history. Does it give you a flight number? If it says "Flight CX880," you can hop on FlightAware and see exactly where that plane is. It’s strangely comforting to see your package flying over the Pacific in real-time.

Third-party apps vs. Carrier sites
- Carrier Sites (DHL, FedEx, UPS): Use these for express shipping. They own the planes, so their data is 100% accurate.
- Aggregators (17Track): Best for "budget" shipping (e-packet, AliExpress Standard). They pull data from over 900 carriers.
- Shop App: Good for a clean interface, but it often lags by 12–24 hours because it relies on API refreshes.
The "Last Mile" mystery
The most frustrating part of knowing how to track overseas packages is the final 20 miles. This is the "last mile" delivery.
Your package might be "In Country," but that doesn't mean it’s on a truck. It has to go through a regional distribution center (RDC). If you’re using a service like DHL eCommerce (which is different from DHL Express), they will often bring the package to your local city and then hand it to the U.S. Postal Service for the actual delivery.
At this stage, you often get a new tracking number. Look for a section on the tracking page that says "Delivery by local courier" or "Partner tracking number." That’s the one you need to put into the USPS or Canada Post website to see exactly which day it’s hitting your porch.
Stop refreshing and take these steps
If you’ve been staring at a "Label Created" status for a week, the seller probably hasn't actually handed the box to the carrier yet. They’ve just printed the sticker.
Here is exactly what to do right now:
- Grab your tracking number and paste it into ParcelsApp. This site is particularly good because it estimates delivery dates based on other users' recent shipments from the same region.
- Identify the "Last Mile" carrier. If the tracking says "tendered to local postal provider," stop checking the international site. Switch to your local national post office website.
- Check the "De Minimis" value. If your order was expensive (over $800 in the US, or much lower in Europe/UK), search your email for "duty" or "customs" to make sure you don't have an unpaid tax bill holding things up.
- Wait for the "Out for Delivery" scan. In international shipping, "Arrival at Destination" usually means the country, not your house. "Arrival at Unit" is the magic phrase that means it's at your local post office.
- Set up alerts. Don't manually refresh. Most aggregators let you plug in an email to get notified only when the status actually changes. It saves your sanity.
International shipping is fundamentally a game of patience. It’s a miracle of the modern world that a $15 gadget can travel 8,000 miles for a few bucks in shipping fees. Give the system time to work, use an aggregator to bridge the data gaps, and always keep an eye out for that secondary local tracking number.
Once the package hits your local sorting facility, you're usually less than 48 hours away from unboxing. Keep the local carrier's app handy for that final stretch, as they will have the most granular data on the driver's route.
