Tracking your 4PX package through Post Tracking is simple and fast. Just follow these steps:
Find the tracking box on the page.
Enter your 4PX tracking number, taken from the seller’s email, receipt, or packing slip.
Click the Track button to start the search.
Review the results, including the package’s current stop, previous movements, and estimated delivery time.
For direct details, head to the official 4PX tracking page. Once there:
Choose your preferred language if needed.
Paste your tracking number into the search field.
Hit the trace button to load the full journey.
You’ll get accurate updates straight from 4PX’s own system, including international transfers, warehouse scans, and customs movement.
Sometimes, 4PX hands packages over to partner couriers. You can use alternative routes to track:
Email or SMS alerts through the 4PX website.
Partner carrier websites like FedEx, UPS, or local postal services are used when the parcel switches hands.
New tracking numbers issued by the partner (your original number often reveals these).
Using these backup methods helps you stay updated even when the parcel changes carriers.
4PX offers several shipping services suited for e-commerce, global sellers, and everyday buyers:
Fast delivery worldwide through partners like FedEx and UPS.
Great for urgent items, usually arriving within 3–7 days.
A hybrid service combining air transit with local postal networks.
Available as ordinary mail, registered mail, or parcel-level shipments.
A partnership with Singapore Post, offering EMS, registered airmail, and standard packet services, is ideal for Asia-Pacific destinations.
Inventory storage and handling from warehouses in China, the US, UK, Germany, and Australia.
Perfect for sellers wanting quicker dispatch and global reach.
Special routes for Amazon, eBay, AliExpress, Temu, and dropshippers.
Includes China pickup, centralized sorting, and delivery via partner couriers.
Most services support parcels up to practical weight limits, but always confirm measurements to avoid delays. 4PX ships to over 200 destinations, specializing in cross-border logistics from China.
As your parcel travels, you’ll see status updates like:
Picked Up – Collected from the seller.
In Processing – Being sorted at a 4PX facility.
Departed Facility – Left a hub and moving onward.
In Transit – Traveling between countries or cities.
Customs Clearance – Under inspection at the border.
Out for Delivery – Local carrier has it on the truck.
Delivered – Completed with time and sometimes a signature.
Exception – Something disrupted the route (address issue, weather, etc.).
These give a clear timeline of each major step.
4PX uses several formats depending on the route:
Pure numbers, such as 1234567890123
Letter + number formats like LX123456789CN, RX123456789HK, RX123456789SG
Codes between 10–20 characters long
You’ll usually find the code in your order confirmation email, seller message, or packaging label.
Sample code: RX987654321SG
Most tracking hiccups are minor. Here’s what they often mean:
Frozen updates – Handoffs to partner couriers or customs inspection can pause scans. Wait 24–48 hours.
Number not found – Try again on both Post Tracking and 4PX. If still blank, contact the seller for confirmation.
Delays – Can occur from holidays, weather, restricted goods, or missing documents.
Delivered but missing – Check neighbors, mailrooms, lockers, or safe-drop spots. Then contact the final-mile carrier.
Knowing these helps avoid unnecessary worry during long international routes.
