Domestic standard parcels
STO's core product: an ordinary parcel moving between Chinese provinces on the line-haul network. This is what most online shopping orders travel on, and it is the service the scan history in the timeline describes.

Chinese domestic parcel network
STO Express Tracking
STO Express, known in Chinese as 申通快递, is one of the large private parcel networks in mainland China. Founded in Shanghai in 1993, it moves mostly e-commerce parcels through a tiered network: a local branch collects, a bagging factory consolidates the parcel for a lane, provincial transfer centres sort it between regions, and a branch at the far end takes it the last few kilometres.
Track91 reads the scan history STO publishes for your waybill and lays it out newest first. STO writes its scans only in Chinese, so each line is kept exactly as sent with an English reading beside it rather than translated away. STO Express official website.
STO Express Services
What STO's timeline shows depends on which part of its network handled the parcel. Service availability, coverage and transit commitments should be confirmed with the shipper or with STO directly.
Parcel stations and lockers
Many Chinese deliveries end at a neighbourhood parcel station (驿站) or a self-service locker (柜机) rather than at the door. STO files a separate scan when one takes the parcel in, and another when you collect it with your pickup code.
Transfer centres and bagging factories
Provincial transfer centres (转运中心) sort parcels between regions, while bagging factories (集包工厂) consolidate them for a single lane. Both appear by name in the history, which is how the route panel knows which hop a scan belongs to.
Returns to the sender
When a parcel cannot be delivered, STO files a return scan and the parcel travels back on the same network. Everything after that scan belongs to the journey home, so a final signature is the shipper's rather than the recipient's.
STO Express tracking number format
A digits-only waybill number
Current STO waybills are 15 digits, most of them opening with 77,
for example 771234567890123.
Labels printed in earlier years carry 12 or 13 digits, such as
123456789012, and are still accepted.
There are no letters and no prefix, which means an STO number looks much like one from several other Chinese networks. ZTO Express issues 14 digits and YTO Express numbers begin with letters, so a number tracked against the wrong company simply returns nothing rather than someone else's parcel. Copy the digits exactly as printed under the barcode.
Expected delivery times
Between major cities
Usually one to three days. The parcel typically passes through two transfer centres, one near the shipper and one near the recipient, with an overnight line haul in between.
To counties and towns
Usually three to five days. An extra provincial hop and a smaller branch at the far end add time, and the final leg may run only once a day.
Shopping festivals
Singles' Day and the June shopping period put the whole network under load, and parcels can sit at a transfer centre for an extra day or two with no scan filed.
Spring Festival
Service is reduced for roughly two weeks around Chinese New Year. Parcels dispatched just before the holiday commonly stop moving until the network restarts.
STO Express tracking status glossary
STO labels each scan with a short Chinese term. These are the ones its trace publishes.
收件 — Picked up
The local branch has collected the parcel from the shipper. This is the first scan of the journey and often carries the parcel's weight.
发件 — Departed
The parcel has left a facility. STO names the facility it is heading to, which is what the route panel uses to draw the next hop.
到件 — Arrived
The parcel has reached a facility. Whether that is a transfer centre, a bagging factory or a local branch is read from the facility's own name.
派件 — Out for delivery
A courier has taken the parcel out of the delivering branch. In most Chinese cities this scan is filed in the morning for the same day's round.
驿站代收 — Held at a parcel station
A neighbourhood parcel station has accepted the parcel on your behalf and is holding it. Collect it with the pickup code the station sends you.
柜机代收 — Held in a parcel locker
A self-service locker is holding the parcel. Lockers usually charge or return the parcel to the branch if it is left uncollected for several days.
客户签收 / 签收 — Signed for
The parcel has been signed for and the journey is finished. Following a station or locker scan it records your collection rather than a delivery to the door.
退回 / 退件 — Return to the sender
The parcel is going back to the shipper. Everything scanned after this belongs to the return journey, including the signature that closes it.

Frequently Asked Questions
Help with STO Express tracking, delays and deliveries. Select a question to read the answer.
How do I track an STO Express parcel?
Enter the STO Express waybill number from your order page, dispatch message or the parcel label in the tracking field on Track91. The newest scan appears first with the dated history below it. The waybill is the only reference STO answers on, so an order number will not return a parcel.
What is the STO Express tracking number format?
STO issues 15-digit waybills, most of them opening with 77, for example 771234567890123. Older labels carry 12 or 13 digits and are still accepted. The number is digits only, with no letters and no prefix, so copy it exactly as printed under the barcode.
What is STO Express and where does it deliver?
STO Express, known in Chinese as 申通快递, is one of the large private parcel networks in mainland China. It was founded in Shanghai in 1993 and runs transfer centres, bagging factories and thousands of local branches covering every province, delivering mostly e-commerce parcels within the country.
How long does STO Express take to deliver in China?
Parcels between major cities usually move in one to three days. Routes into remote counties and towns typically take three to five days because the parcel passes through an extra provincial transfer centre. Shopping festivals and the Spring Festival holiday add noticeable delays to both.
Why is my STO Express tracking in Chinese?
STO publishes its scan history only in Chinese, using short labels such as 收件 for a pickup, 发件 for a departure and 到件 for an arrival. Track91 keeps that text exactly as STO sends it and adds an English reading beside each line, rather than translating the original away.
What does 驿站代收 mean on STO Express tracking?
It means a neighbourhood parcel station has taken the parcel in on your behalf and is holding it for collection. The related 柜机代收 means a self-service parcel locker is holding it instead. Both are followed by a signature scan once you collect, not by a delivery to your door.
Why is my STO Express tracking not updating?
The long quiet gaps are the line hauls between provincial transfer centres, where no scan is filed for many hours. A parcel collected late in the day may also not appear until the branch closes its manifest that night. Compare the last scan with the usual route time first.
Can I track STO Express without the waybill number?
Not on Track91. The lookup needs the waybill, because that is the only identifier the STO trace resolves. Check your order history, the seller dispatch message or the printed label. A recipient name, phone number, address or shop order reference cannot be used instead.
What should I do about a delayed or missing STO Express parcel?
Contact the seller or shipper first with the waybill number and the last scan, because they hold the contract with STO. The branch that last scanned the parcel is named in the history and can be asked directly. Numbers more than a few months old stop returning any history.
Is STO Express the same as ZTO or YTO Express?
No. STO, ZTO and YTO are three separate Chinese parcel companies with similar names and overlapping coverage. Their waybill formats differ, so a number tracked on the wrong one simply returns nothing. STO is 申通快递, ZTO is 中通快递 and YTO is 圆通速递.
Is Track91 affiliated with STO Express?
No. Track91 is an independent tracking service and is not affiliated with STO Express or 申通快递. It shows the shipment information STO publishes for a waybill, for convenience. Redirections, delivery instructions, refunds and claims must be handled by the shipper or by STO directly.
