How to Track Shipments from China (All Methods)

Every shipment leaving China carries a tracking identity, and that identity decides where you look it up. Most tracking confusion comes from putting the right number into the wrong system: a sea container number into a parcel tracker, a forwarder's internal reference into a carrier site. Get the number into the right tool and the mystery usually disappears.

The rule for the rest of this guide is simple. Identify which number you have, match it to its system, and read the statuses for what they are. CN Ally coordinates logistics and consolidation for China imports, and tracking is where most buyers first discover how a shipment was actually structured.

Your Tracking Number Already Tells You What to Do

Before you open any tracking site, read the number. Its shape reveals the shipping mode, the carrier, and the only lookup tool that will recognize it.

How to decode a tracking number from China:

What the number looks like · What you have · Where to track it

• 13 characters, ends in CN, starts with R, E, C, L, or U (e.g. `RR123456785CN`): China Post / postal item under the UPU S10 standard · China Post site, 17Track, ParcelsApp
• 10 digits (e.g. `1234567890`), sometimes with a JD prefix in China: DHL Express waybill · DHL tracking
• `1Z` followed by 16 characters (e.g. `1Z999A99W999999999`): UPS waybill · UPS tracking
• 12 digits (e.g. `123456789012`): FedEx waybill · FedEx tracking
• 11 digits, usually shown with a dash after the first 3 (e.g. `784-12345675`): Air waybill (AWB), air cargo · Track-Trace air cargo, the airline's cargo site
• 4 letters + 7 digits (e.g. `MSCU1234567`): Sea container number under ISO 6346 · Track-Trace container, the shipping line's site
• A booking or reference code from your forwarder, often with letters and slashes: Bill of lading (B/L) number, or a forwarder internal reference · The shipping line or your forwarder's portal
• A number the forwarder calls a "tracking ID" that no public tool recognizes: DDP special-line or consolidation reference · Your forwarder's tracking page, not a carrier site

The postal format follows the UPU S10 standard): two letters for the service, an eight-digit serial, one check digit, and the country code. The first two letters identify the product: R is registered mail, E is EMS express, C a parcel, L a tracked letter, U an unregistered or economy item. That last group matters. Economy items typically scan only while still in China and go dark after export, because nothing scans them at transit points. A "CN" number starting with U that stops updating after leaving China is usually the product behaving as designed, not a lost package.

The sea container number follows ISO 6346: three letters for the owner, one for the equipment category, a six-digit serial, and one check digit. Mistype a single character and the tracker returns nothing instead of correcting you. That is the most common cause of "invalid tracking number" panic in sea freight, and it is fixed by reading the number off the bill of lading rather than from memory.

Postal Shipments: China Post and EMS

Postal items are the cheapest to ship from China and the slowest to update. Registered airmail typically takes two to four weeks to reach Europe or North America, EMS roughly half of that. During the first leg, updates come from China Post's own scans. Once the item reaches your country, your national post takes over, and your home postal site often shows more detail than the Chinese one did.

Keep expectations honest about the middle of the trip. A scan that says the item left China can sit unchanged for ten days or more while the parcel rides in a mail bag on a commercial flight. Silence during that window is normal. When tracking genuinely stalls, work through the causes in order. The number may be unregistered, in which case updates stop at export. The seller may have created the number but never posted the item. Or the item may be sitting in customs, which shows as a long pause at an arrival scan. If nothing moves for more than two weeks past the seller's promised window, ask for proof of posting rather than refreshing the tracker.

Express Shipments: DHL, FedEx, UPS, and SF Express

Express tracking is the most detailed you will get, because the courier scans at every handoff and publishes it all. Paste the waybill into the carrier's own site; the format check in the table above tells you which carrier owns the number.

Three quirks cause most confusion. First, a sender can create a waybill and print a label before collection, so the page shows "shipment information received" for a day or two. That means the courier knows the parcel exists, not that it is moving. Second, express from China sometimes travels under the sender's carrier account rather than a public waybill, especially forwarded express. Ask for the waybill number specifically, not "the DHL number." Third, SF Express is a major Chinese carrier many Western buyers overlook. Its international shipments track on its own site and on aggregators, but its numbers return nothing on DHL or FedEx.

Express statuses are the easiest to read. They say exactly where the parcel is, and when one says the parcel cleared customs in your country, delivery is usually a day or two away.

Air Cargo: Reading an Air Waybill

General air cargo moves under an air waybill, an eleven-digit number where the first three digits identify the airline. Unlike express, this is freight tracking rather than parcel tracking. You will see scans at departure, at the destination airport, and at customs clearance, with long quiet stretches between them while the cargo is in the air or sitting in the origin terminal.

Track through Track-Trace's air cargo section or directly on the airline's cargo website. You need the airline name, because each carrier's site only knows its own waybills. Your forwarder should have told you which airline was booked. If you do not know, the three-digit prefix identifies it.

One gap to understand: if your goods flew consolidated with other shippers, you are holding a house air waybill issued by the forwarder, not the airline's master waybill. The airline's site will not know your number. Only the forwarder's portal shows the house waybill. When you buy air freight, ask upfront whether the booking is direct or consolidated, so you know which number to watch.

Sea Freight: Containers, Bills of Lading, and the Master-House Problem

Sea freight tracking starts with knowing whether you shipped FCL or LCL, because the two track differently. A full container load is straightforward. You get a container number in the ISO 6346 format, and you can follow it on the shipping line's website, on Track-Trace, or even on a public AIS vessel tracker like MarineTraffic once you know the vessel name. The carrier sites for the big lines, Maersk and COSCO among them, accept the container number directly.

LCL is where importers lose their way. In a less-than-container-load shipment your cartons share a container with other buyers' goods, and the container number belongs to the consolidator's contract, not to you. Tracking that number on a carrier site will show a container that apparently contains nothing of yours. From the carrier's perspective, that is correct. What you track is the house bill of lading your forwarder issued, and that only works in the forwarder's system.

Even in FCL, the bill of lading number matters as much as the container number. The carrier's site usually accepts both, but a B/L from a forwarder acting as an NVOCC is a house bill, and the same master-versus-house split applies. Whenever a sea tracking number returns nothing on a public tool, the first question is not "where is my cargo" but "who issued this number."

Expect scans at loading, departure, transshipment ports, and arrival, with long quiet stretches between them. Check at the waypoints: departed, transshipped, arrived.

Rail Freight: Tracking the China-Europe Trains

China-Europe rail freight sits between sea and air on both speed and tracking transparency. A train from a hub like Xi'an to Duisburg can arrive in roughly two weeks, and the tracking reflects that compact journey: fewer waypoints, more border crossings, each a potential pause.

The practical difference is that rail has no universal public tracker. Your forwarder or rail operator tracks through the carrier's own system and reports to you. The pauses are real, too. Every gauge change involves a crane transfer and a queue, and the queue is where the schedule variance lives. A tracking page showing your train at a border for two days is showing normal operations.

If you are new to this mode, the China-Europe rail freight guide covers the routes and corridors. For tracking, the rule holds: rail numbers belong to the operator that sold the space, and only their system reads them.

DDP, Special Lines, and 1688 Agent Shipments

The shipments that generate the most tracking questions are the ones where the number changes hands. In DDP and special-line services, and in agent-consolidated shipments from platforms like 1688, your goods pass through several operators between the Chinese warehouse and your door. Each operator issues its own reference, and only some of them appear on public trackers.

The pattern is almost always the same. You get a forwarder-issued reference that works in the forwarder's own system. During the long leg and customs clearance, updates are sparse, because nothing in that chain publishes public scans under your reference. Once the goods clear customs in your country, a last-mile carrier takes over and generates a new tracking number. Your original number may show "delivered" at the handoff, or simply go quiet. That is the handoff, not a failure.

The critical habit for these shipments: ask your forwarder for both numbers, the internal reference for the first legs and the last-mile carrier's number for the final one. The DDP shipping explainer covers how these door-to-door services are structured, which tells you whose scans to expect and when.

The critical habit for these shipments: ask your forwarder for both numbers. The internal reference for the first two legs, the last-mile carrier's number for the final one. If you only have the first, you will stare at a quiet page while your goods are actually moving through customs. And if a forwarder cannot give you either, that is a service-quality signal worth noting when you choose a freight forwarder. The DDP shipping explainer covers how these door-to-door services are structured, which helps you understand whose scans you should expect and when.

The Tools, Ranked by When to Use Them

You do not need ten trackers. You need the right one for the number in your hand.

Tool · Best for · Limitation

• Carrier's own site (DHL, FedEx, UPS, Maersk, COSCO): The number the carrier itself issued · Only knows its own numbers
• China Post official site: Postal items from China · Chinese-language heavy at times; home post shows more after arrival
• 17Track: Postal and express aggregator, one view for many carriers · Coverage of sea/air B/L numbers is thin
• ParcelsApp: Postal parcels, especially from Chinese marketplaces · Postal only
• Parcel Monitor: Multi-carrier parcels with multi-language display · Postal and express focus
• Track-Trace: Air waybills and sea containers across carriers · Sea and air only, interface shows its age
• MarineTraffic: Live vessel position on AIS once you know the vessel · Shows the ship, not your container
• Your forwarder's portal: House B/Ls, DDP numbers, consolidation references · Only works for that forwarder's shipments

When Tracking Stalls: Diagnose Before You Panic

Stalled tracking almost always falls into one of five patterns. Match the symptom to the pattern before escalating.

The number shows nothing at all. Check the format first: one wrong character in a container number returns zero results. Confirm you are using the issuer's own system, since a house B/L in a carrier's tracker always comes back empty. If both are right, the shipment may not have been tendered yet. A created label is not a collected parcel.

No updates for several days mid-journey. For sea freight, this is the ocean leg; for postal, the flight; for rail, possibly a border queue. All normal. For express, not normal past two or three days. Match your worry to the mode.

"Departed country of origin," then silence. The item left China but has not been scanned at the destination. Postal bags wait for flights; consolidated express waits for the forwarder to break bulk and hand to last-mile. A week for postal, a few days for express, then contact the sender.

Stuck at customs or "held for inspection." Export customs in China usually clears in a day or two. Import customs can hold a shipment for examination. Past a week with no movement, ask the broker or forwarder what documentation customs wants. The fix is almost always paperwork.

Delivered, but you never received it. Check the delivery proof: name or signature captured, address listed, any photo. Parcels land at neighbors, concierge desks, and wrong-but-close addresses more often than they get stolen. Confirm the address on file before assuming loss, and file promptly if the proof is wrong, since carriers have claim time limits.

Reading Tracking Statuses

Status · What it means · What to do

• Label created / picked up: The carrier knows the shipment exists; collection is pending · The clock starts at the first collection scan
• Departed origin / in transit: Moving between hubs · Nothing; check again at the expected waypoint
• Arrived at destination country: Landed, not yet cleared · Normal; customs is next
• Customs clearance: At customs (export or import); a "held" variant means the authorities want documentation · Normal for a few days; past a week, contact your broker or forwarder for what is needed
• Out for delivery: On the last-mile vehicle · Be available; check the delivery instructions
• Delivered: Handed over per the carrier's record · Verify the proof; dispute promptly if wrong
• Exception: Something needs a decision · Read the attached detail; exceptions usually name what is missing

Frequently Asked Questions

Why did my tracking stop updating after the package left China?

Usually the flight leg, where nothing scans the parcel for days. Your national post often picks up scanning once the item arrives and clears. For unregistered economy items, tracking may never resume after export, since no transit scans are taken. Give registered items a week of silence before worrying, and check your home post's site, not just the Chinese one.

My forwarder gave me a tracking number that no website recognizes. Is it fake?

Probably not. Forwarders running DDP, special lines, and consolidation issue their own references, which only work in the forwarder's tracking system. Ask for the forwarder's tracking page, and ask whether a last-mile carrier number will be issued after customs clearance. A reference that works nowhere, including the forwarder's own site, is a different story.

Can I track a container by its number?

Yes, for an FCL container, through Track-Trace or the shipping line's own site. The ISO 6346 number identifies the box itself. If your shipment is LCL, you share the container, and its number says nothing about your cartons. Track your house bill of lading in your forwarder's system instead.

What is the difference between a master and a house bill of lading?

A master bill of lading is issued by the actual carrier and covers the forwarder's booking. A house bill is issued by the forwarder to you, covering your part of a consolidated shipment. Public trackers only know master numbers. Your forwarder's portal is where house numbers live.

The One Rule That Settles Every Tracking Question

Match the number to its issuer, and use the issuer's system. Postal number to the post, express waybill to the courier, container to the shipping line, forwarder reference to the forwarder's portal. Nearly every tracking mystery is a number in the wrong tool.

Settle the tracking question at booking time, not at worry time: ask who issues the tracking number, where it will work, and whether a second number arrives after customs. If you would rather have one accountable party handling the shipment and the tracking, write to hi@cnally.com.
