STO Express Tracking

STO Express tracking follows a parcel from pickup in China through sorting and final delivery, whether it moves across a single Chinese city or crosses a border to one of more than 200 countries served by STO Global. STO Express (officially Shanghai STO Express Co., Ltd., known in Chinese as Shentong Express, 申通快递) delivered about 22.7 billion parcels in 2024, placing it among the top five express carriers in China by volume (Statista, 2024). Paste an STO Express tracking number into the tracker on this page to see the latest scan, including the destination-carrier events after a cross-border handoff.

STO Express Tracking Number Format

An STO Express domestic tracking number, called the waybill number, is an all-numeric code of 10, 12, or 14 digits printed on the shipping label. STO uses plain numeric references for its Chinese network rather than the letter-based UPU S10 format (the AA000000000CN style used for registered China Post items), so an STO number carries no country letters. For cross-border shipments, STO Global issues its own reference that some aggregators display with an "STO" prefix followed by digits, and that reference is often paired with a separate tracking number from the postal or courier partner that completes delivery abroad.

The waybill number is the primary identifier for every STO shipment and is different from the shop order number. An online order confirmation shows an order or reference ID used by the retailer, while the trackable STO code is the numeric waybill generated when the parcel enters STO's network. Because STO numbers are plain digits, they can resemble those of other Chinese carriers such as YTO Express and ZTO Express, so a universal tracker that detects the carrier automatically avoids checking the wrong network.

Where to Find STO Express Tracking Number

The STO Express tracking number is assigned when the parcel is booked and appears in several places depending on how it was sent:

• On the paper waybill or shipping label attached to the parcel.
• In the shipping confirmation email or SMS from the online store.
• In the order or logistics section of the marketplace where the item was bought.
• On the drop-off or pickup receipt when a parcel is handed in at an STO service outlet.

The waybill number is not the same as the retailer's order number. The order confirmation carries an order or reference ID used by the shop, whereas the trackable STO code is the numeric waybill created once the parcel is collected into STO's network, and it is that number the tracker on this page needs. On a cross-border order the shop may show the STO Global reference first and only reveal the destination-carrier number after the parcel arrives in the destination country.

STO Express Tracking Number Example

The table below lists the number formats seen on STO Express shipments and what each one indicates. STO does not publish a documented prefix-to-service scheme for its domestic waybills, so the digit-count patterns below are the commonly seen formats rather than a guaranteed service indicator.

A domestic STO waybill is numeric with no country letters. A code that starts with two letters and ends in "CN" is most likely a registered China Post item rather than an STO number, in which case it should be tracked as China Post.

STO Express Tracking Status Guide

STO Express tracking moves through a defined sequence of scans from collection to delivery. The table below explains the statuses seen most often on STO Express shipments.

Why STO Express Tracking Is Not Updating or Not Working

Most cases where STO Express tracking is not updating or not working are normal gaps between scans rather than a lost parcel. The stages below explain the common reasons and what each one means.

Awaiting the first scan. A newly created waybill can show "shipping information received" or return no result for 24 to 48 hours before the parcel is physically collected. Until STO takes possession there are no transit scans, so a brand-new number that shows nothing usually just needs time.

In transit between hubs. On long domestic routes across China the parcel can travel for a day or more between recorded scans, and a quiet spell mid-journey does not mean the item is stuck. Peak periods such as the November 11 shopping festival add backlog at sorting hubs, where STO's network has handled tens of millions of parcels in a single day.

Cross-border handoff gap. This is the most common reason an international STO parcel looks quiet: STO Global has exported it from China but the destination carrier has not yet recorded its first scan. Updates resume once the local postal operator or courier scans the parcel in.

Customs clearance. International parcels can rest on "export" or "customs clearance" while the shipment is checked and any duties are assessed. Clearance can take several days, and tracking resumes once the item is released to the local carrier.

Wrong number or a second leg. A single mistyped digit returns an empty result, and an order number entered instead of the waybill will not resolve. For cross-border parcels the last-mile carrier may track under a different number, so check whether a destination-carrier number has been issued.

Genuinely delayed. If the number is correct and nothing has moved for many days beyond the expected window, the seller holds the shipping contract as STO's direct customer and should open an enquiry with STO, quoting the waybill number and dispatch date.

Services and Delivery Times Compared

STO Express built its business on high-volume domestic e-commerce delivery, then expanded into warehousing, cold chain, and cross-border logistics through STO Global. The table below compares the main services and their typical delivery windows.

STO calculates charges on the higher of a parcel's actual weight or its volumetric (dimensional) weight, measured in kilograms to at least one decimal place, and it announced standardized volumetric-weight rules across the network in July 2025 (STO Express, 2025). Because STO runs a franchise network, retail pricing at individual outlets can vary within central guidelines, while high-volume merchants negotiate rates directly or through the Cainiao platform. For e-commerce merchants the B2C one-stop service also covers cash-on-delivery and collection-on-delivery, payment options that remain common in the Chinese domestic market and are coordinated through the Cainiao platform on Taobao and Tmall orders.

Delivery and Transit Times by Destination

Domestic parcels within mainland China typically arrive in 1 to 3 business days, with same-day or next-day service common within the same city or between closely connected cities, especially across the Yangtze River Delta (Shanghai, Suzhou, Hangzhou, Nanjing) and the Pearl River Delta (Guangzhou, Shenzhen, Dongguan). Deliveries to remote or rural areas served through the franchise partner network, including lower-tier cities and townships in the west and northeast, can use the full 3-day window or slightly longer.

Cross-border parcels handled by STO Global generally take 5 to 10 business days from the export date, with East Asia, Western Europe, and North America toward the faster end and more distant or customs-heavy destinations toward the slower end. Ordertracker lists an average end-to-end window of 7 to 90 days for international STO parcels once slow customs and remote last-mile legs are included (ordertracker.com, 2024). All timeframes are estimates rather than guarantees, and customs handling in the destination country can extend delivery. STO's growing overseas-warehouse network shortens cross-border transit in key markets by positioning inventory locally before orders are placed, so an item shipped from a local warehouse skips the individual customs clearance that a direct-from-China parcel must pass.

Delivery Options, Returns, and Claims

Standard STO delivery is made to the recipient's registered address with signature confirmation, and where the recipient is unavailable the courier may use a Cainiao smart locker, a Cainiao Post pickup station, a neighbour or concierge, or a follow-up attempt. This locker and pickup-station network expanded across China's urban and suburban areas as part of a national shift toward unmanned delivery. Recipients who expect to be out can, in many areas, redirect a parcel to a nearby locker or Cainiao Post station before the final out-for-delivery scan, after which rerouting options become limited.

For a lost, badly delayed, or damaged parcel, STO customer service should be contacted promptly on +86 400 810 1111, with English-language support via 95543-4 at extension 5 (STO Express, 2024). Damaged items should be photographed before and after unpacking, and the original packaging and waybill retained, because most carriers apply internal deadlines for claims. High-value shipments sent through the Valuables Channel carry a declared-value and insurance framework with defined compensation; standard uninsured parcels follow STO's general terms, which typically apply lower limits, so declaring value and buying coverage at the time of sending is advisable for costly goods.

Which Countries Does STO Express Deliver To?

STO Express international tracking follows parcels through STO Global to more than 200 countries and territories, while its domestic network of 30,000 to 40,000 service outlets covers all of mainland China. Domestic infrastructure is concentrated in the Yangtze River Delta (Shanghai, Jiangsu, Zhejiang), the Pearl River Delta (Guangdong), and the Beijing-Tianjin-Hebei corridor, with warehouse and distribution capacity exceeding 2 million square metres across more than 300 facilities in 56 cities (ordertracker.com, 2024).

Internationally, STO Global focuses on markets relevant to Chinese export e-commerce and hands parcels to a local postal operator or courier for final delivery in the destination country. In the United Kingdom and Canada, for example, last-mile delivery is often completed by partners such as Royal Mail and Canada Post, so late tracking events appear under the local carrier.

• Domestic: all 23 provinces, 5 autonomous regions, 4 municipalities, and 2 special administrative regions of China.
• East Asia: Japan, South Korea, Taiwan, Hong Kong, and Macau.
• Southeast Asia: Indonesia, Malaysia, Thailand, Vietnam, the Philippines, and Singapore.
• Europe: the United Kingdom, France, Germany, Italy, Spain, and the Netherlands.
• North America: the United States and Canada.
• Other regions: Russia and Central Asia, plus destinations across the Middle East, Latin America, Africa, and Oceania.

Cross-Border Customs and International Handoff

For cross-border shipments, STO Global manages the outbound export, freight, and customs documentation from the Chinese side, then hands the parcel to a partner in the destination country for last-mile delivery. After this handoff, scans switch from STO's network to the receiving carrier, so the place where updates appear changes and a separate destination-carrier number may be issued.

Whether duties and taxes fall on the sender or the recipient depends on the service: high-volume merchants can arrange Delivered Duty Paid (DDP) terms, under which the logistics operator manages and pays import taxes before delivery, while general international parcels usually ship Delivered Duty Unpaid (DDU), with the recipient paying applicable import duties before release. Prohibited items include hazardous materials, firearms, explosives, counterfeit goods, and anything restricted under Chinese export or destination-country import law. A universal tracker stitches the STO scans and the local-carrier scans together under one lookup, so there is no need to guess which website to check.

Marketplace Collaborations

STO Express is one of the primary carriers fulfilling orders from Alibaba's marketplaces, a relationship reinforced when Cainiao Smart Logistics Network, Alibaba's logistics affiliate, acquired roughly 25% of STO in 2019 (ordertracker.com, 2024). Parcels bought on Taobao and Tmall are routinely routed to STO through the Cainiao network, which coordinates warehousing, last-mile logistics, and locker or pickup-station delivery on the merchant's behalf.

For cross-border shoppers, STO Global carries goods sold on China-based platforms such as AliExpress, Temu, and Shein out of China, handing them to a local operator abroad for final delivery. In every case the seller supplies the STO waybill number, and the same lookup on this page follows the parcel from China through to the destination carrier.

Domestic Network and Sorting Infrastructure

STO Express runs roughly 77 transshipment centres and a fleet of about 4,000 line-haul vehicles that move parcels between hubs across mainland China (ordertracker.com, 2024). This trunk network connects the 30,000 to 40,000 franchise service outlets that handle first-mile pickup and last-mile delivery, so a typical parcel is scanned at an origin outlet, consolidated at a regional transshipment centre, line-hauled to a centre near the destination, then broken down for local delivery.

The company's parcel volume has grown quickly: it reached about 22.7 billion parcels in 2024 and a reported 26.1 billion in the following period, lifting its market share to around 13% of the Chinese express market (STO Express financial results, 2026). Automated cross-belt sorters at the major hubs let STO process very high daily volumes, which is what allows next-day delivery across the dense eastern corridors even as national volumes climb each year. Because the outlets are independently operated franchises, service quality and pickup speed can vary between regions, though the sorting and line-haul backbone is centrally managed by the listed parent.

What Is STO Express (Shentong)?

STO Express, officially Shanghai STO Express Co., Ltd. and known in Chinese as Shentong Express (申通快递), is one of China's largest private express delivery companies, founded in February 1993 in Shanghai as the Shentong Integrated Service Department. It was among the very first private couriers in China at a time when domestic express delivery was dominated by state-owned postal services, and it is widely credited with pioneering the express franchise model, under which STO runs the core sorting hubs and long-haul transport while independent franchise partners handle local pickup and delivery.

STO expanded methodically from its Yangtze River Delta base: it reached Nanjing and Suzhou by 1996, Beijing and Guangzhou by 1997, and held roughly 30% of the Yangtze River Delta express market by 2004. The corporate entity Shentong Express Co., Ltd. was formally established in 2007, and on 30 December 2016 the company listed on the Shenzhen Stock Exchange under ticker 002468. In 2018 a high-speed train was named the "Shentong Express" service, the first Chinese high-speed rail line to carry a private courier's name.

In 2024 STO reported operating revenue of about 47.2 billion yuan and roughly 22.7 billion parcels delivered, one of the top-five volumes in China (Statista, 2024). Its 2019 tie-up with Alibaba and Cainiao makes it a core carrier for Chinese e-commerce, alongside Tongda-group peers such as Yunda Express.
