Chukou1, also known as 出口易, is a cross-border e-commerce logistics brand established in 2009 under Guangzhou BFE Information Technology Co., Ltd. The company specializes in helping online sellers move and fulfill goods internationally through overseas warehousing, international first-mile transport, dedicated shipping lines and related logistics services. Its verified own operations include processing facilities in China and overseas warehouse operations in the United States, United Kingdom, Germany, France, Poland, Australia, Canada, Peru and Argentina.
Overseas warehousing is a major part of Chukou1's service model. Sellers can ship inventory to warehouses closer to their customers and then use services such as storage, inventory management, order processing, picking and packing, local fulfillment and returns. This model supports local sales without requiring every customer order to begin its journey from the seller's origin country.
Chukou1 also operates international dedicated lines and first-mile services for cross-border sellers. Its current service portfolio includes direct shipping lines for destinations in North America, Europe and Latin America, as well as air freight, sea freight, Amazon FBA first-mile transportation and customized logistics solutions. Some services combine international transport, customs handling and final-mile delivery within one logistics workflow.
Shipment visibility is integrated into these services. Chukou1 provides online logistics Tracking for packages and freight, and some shipments can receive both a Chukou1 processing number and a separate tracking number from the local delivery provider. Recipients can also Track Chukou1 packages through 4Tracking, a universal package tracking website that helps follow shipments even when several logistics companies participate in the journey.
How Chukou1 shipment tracking works
Chukou1 uses a processing number, referred to in its Chinese documentation as a 处理号, to identify shipments within its logistics system. Customers can enter this number into Chukou1's tracking platform to follow available events generated during processing and transportation.
Official Chukou1 guidance shows that Tracking can cover several stages of an international shipment, including processing at the domestic warehouse, handover to a service provider, departure, customs clearance and local delivery. The exact amount of information depends on the shipping product and the partner responsible for the destination stage.
A package can also receive a separate final-mile tracking number. Chukou1's official guidance for marketplace sellers specifically distinguishes its own processing number from the last-mile carrier's tracking number. This means two identifiers associated with the same package can both be legitimate and may provide information about different parts of the journey.
How to Track Chukou1 packages with 4Tracking
To Track a Chukou1 package on 4Tracking, paste the shipment or processing number into the tracking field. 4Tracking can automatically identify Chukou1 when the number is recognized, or you can select Chukou1 manually. Press the Track button to open the results page and review the latest available package tracking events.
You can also use Chukou1's official EC-FirstClass tracking platform. Its current global shipment tracker supports multiple tracking numbers and can display logistics information from Chukou1 and cooperating postal or courier networks.
Chukou1 tracking number formats
Chukou1's official documentation consistently refers to its internal shipment identifier as a processing number, but the company does not publish one current universal specification defining a fixed prefix, length or combination of letters and digits for every Chukou1 logistics product.
Formats can also differ because a shipment may receive a number from the destination delivery partner. Chukou1 has explicitly instructed Amazon marketplace sellers using supported services to submit the Chukou1 processing number rather than the final-mile tracking number, confirming that these identifiers can be different.
Enter the complete number exactly as supplied by Chukou1 or the seller. Do not remove letters, leading zeros or other characters to make the number resemble an unofficial example. If you have both a Chukou1 processing number and a local carrier number, keep both because each may be useful for Tracking a different stage of the shipment.
Chukou1 delivery times and examples
Chukou1 does not have one delivery time that applies to every shipment. The company offers international direct lines, air and sea first-mile transportation, overseas warehouse fulfillment and local delivery services, and each product has its own route-specific timing.
For current overseas-warehouse first-mile air services, Chukou1 lists approximately 3 to 5 days for its Super Air service to the United States and approximately 6 to 8 days for Germany and France. Its Economy Air service to the United States and Canada is listed at approximately 8 to 10 days. These are service-specific warehouse-arrival timeframes rather than universal consumer parcel delivery promises.
Sea freight takes longer. Chukou1's current overseas-warehouse first-mile information lists examples such as approximately 15 to 18 days to the western United States and 25 to 28 days to the eastern United States using one Matson ocean service. Other sea products publish different schedules, including approximately 25 to 38 days for standard ocean freight to the United States, 35 to 40 days to Canada and 22 to 32 days to Australia.
Local fulfillment from Chukou1's South American warehouses has its own timing. The company's Peru warehouse lists approximately 3 to 5 days for local delivery in Lima and 8 to 12 days outside Lima. Its Argentina operation lists approximately 3 to 5 days within the Buenos Aires metropolitan area and 7 to 9 days for interior destinations. These examples apply to the specified local services and should not be used as estimates for unrelated Chukou1 routes.
How to contact Chukou1 about shipment issues
Chukou1's official nationwide customer-service hotline is 4006 908 223. The company also publishes a Guangzhou headquarters number of 020-23380666, a Shenzhen office number of 0755-28263408 and a Shanghai office number of 021-59793099.
For complaints, Chukou1 lists 13360562736, with the complaint line available Monday through Friday. Its official claims email is gzck1care@chukou1.com. Chukou1 also identifies mkt@chukou1.com as an official company email address for general official communications.
If the problem concerns an online purchase, contacting the seller can also be useful. The sender has access to the original Chukou1 order, processing number, selected logistics product and any final-mile tracking number, making it easier to verify whether the shipment has been dispatched correctly or to open an investigation.
Frequently asked questions about Chukou1 package tracking issues
Why is my Chukou1 tracking number not working?
Check that you entered the complete Chukou1 processing or tracking number rather than a marketplace order number. A recently created shipment may also require time before its first logistics event appears. If the problem continues, ask the sender to confirm the correct processing number.
What format does a Chukou1 tracking number use?
Chukou1 does not publish one universal current format covering every service. Its system uses processing numbers, while some shipments also receive a separate last-mile tracking number. Use the complete identifier supplied for your individual shipment rather than assuming a particular prefix or length.
What is a Chukou1 processing number?
The processing number is the identifier Chukou1 uses for a shipment inside its logistics system. It can be used to follow available events through Chukou1's Tracking services and may differ from the tracking number assigned by the final delivery carrier.
How do I Track a Chukou1 package on 4Tracking?
Enter the Chukou1 shipment or processing number into 4Tracking, allow the system to detect the carrier automatically when possible or select Chukou1 manually, and press Track. The results page will show the latest available package tracking information.
Why do I have two tracking numbers for the same Chukou1 package?
One identifier may be Chukou1's processing number while another belongs to the destination or final-mile carrier. Chukou1's own marketplace guidance distinguishes between these two identifiers, so both numbers can legitimately refer to the same shipment.
Why has my Chukou1 Tracking stopped updating?
An international package can spend time in transportation, customs processing or a carrier handover without generating a new public event immediately. If another local tracking number has been issued, check that number as well. Contact the seller or Chukou1 if the shipment remains unchanged significantly beyond its expected service timeframe.
How long does Chukou1 delivery take?
Delivery time depends on the product and route. Current official examples range from approximately 3 to 5 days for certain air first-mile and local warehouse services to several weeks for ocean freight. Use the timing published for the specific Chukou1 service selected by the sender rather than applying one timeframe to every package.
Where does Chukou1 have its own operations?
Chukou1 operates processing facilities in China and reports self-operated overseas warehouse centers in the United States, United Kingdom, Germany, France, Poland, Australia, Canada, Peru and Argentina.
Does Chukou1 provide overseas warehouse fulfillment?
Yes. Overseas warehousing is one of Chukou1's main services. Its warehouses support inventory storage, order processing, local fulfillment, returns and other services that allow sellers to keep goods close to customers in major e-commerce markets.
Does Chukou1 provide air and sea freight?
Yes. Chukou1 provides air and sea first-mile transportation for overseas warehouses, Amazon FBA warehouses and other destinations. Available routes and transit times depend on the selected transport product.
What should I do if my Chukou1 package appears lost?
Review both the Chukou1 processing number and any final-mile tracking number for the latest event. If the shipment is significantly overdue, contact the seller or Chukou1 customer service with both identifiers and the shipment details so the appropriate logistics stage can be investigated.
How can I make a complaint or claim about a Chukou1 shipment?
Chukou1 publishes 13360562736 as its complaint telephone number for Monday through Friday and gzck1care@chukou1.com as its claims email address. Include the processing number, shipment information and relevant evidence when requesting assistance.
