AAF, also known as Meitong Supply Chain, is a China-based cross-border logistics company whose operations began in 2008. Headquartered in Shenzhen, the company focuses on international logistics for cross-border e-commerce sellers, providing transportation, customs-related services, destination delivery and warehousing through a network of domestic and overseas branches.
AAF's main transportation products include air freight and air-delivery services, ocean freight, international trucking and multimodal logistics. Its network is particularly oriented toward e-commerce and Amazon FBA first-mile transportation, with dedicated services for destinations such as the United States, the European Union, the United Kingdom, Canada and Japan. The company also handles customs clearance and coordinates final delivery after international transportation.
AAF operates an extensive company network in China and officially lists overseas branches in the United States, United Kingdom, Belgium, France, Germany, Canada, Japan, Mexico, Kazakhstan, Vietnam, Peru, Australia, Belarus, Ecuador and Guatemala. Its global network includes locations such as Los Angeles, New York, London, Liège, Paris, Frankfurt, Vancouver, Tokyo, Mexico City, Almaty, Hanoi, Sydney and other logistics centers. The company also operates or manages overseas warehousing resources in several major e-commerce markets.
Warehousing services include temporary storage and transfer, fulfillment, returns, relabeling, inspection and after-sales handling. AAF says its warehouse systems can connect with more than 40 e-commerce platforms, helping sellers manage orders from warehouse entry through final delivery while maintaining digital shipment visibility.
How AAF shipment tracking works
To Track an AAF package with 4Tracking, enter the shipment tracking number in the tracking field. Select AAF if a carrier button is displayed, or allow 4Tracking's automatic carrier detection to identify the logistics provider. Press the Track button and you will be redirected to the results page, where the available package tracking events and latest shipment status are shown.
AAF also provides a shipment-trajectory search field on its official website. Cross-border shipments may pass through several stages, including receipt at an AAF warehouse, export processing, international air, sea or road transportation, destination customs clearance and final delivery. Tracking visibility can therefore come from both AAF and a last-mile carrier.
This is particularly important for shipments transferred to companies such as FedEx or UPS. AAF states that for its United States air service, a FedEx tracking number can be generated after the cargo is handed to AAF, but the FedEx movement becomes available online after the shipment clears customs in the United States. A package can therefore have an AAF-related shipment reference as well as a separate last-mile tracking number.
AAF tracking number formats
AAF does not publish a universal public specification defining one mandatory length, prefix or combination of letters and digits for all of its shipment numbers. Its official website provides a trajectory-search function but does not state that every shipment identifier follows one fixed format.
Because AAF handles air freight, ocean freight, trucking, FBA shipments and deliveries completed by other carriers, the identifiers associated with a shipment can differ by product and delivery stage. Use the complete number supplied by AAF, your freight forwarder, seller or shipping confirmation rather than changing it to fit an assumed pattern.
A final-mile number may also be issued separately. For example, AAF officially confirms that FedEx tracking numbers are generated for relevant United States air shipments. Since AAF does not publish a sample AAF number or a fixed syntax for its own general tracking references, it would be unreliable to present an invented number pattern as a standard format.
AAF delivery times and supported examples
AAF does not publish one universal delivery-time promise covering every country and service. Transit time depends on whether the shipment travels by air, sea, road or a combination of methods, as well as the selected route, departure schedule, customs processing and final-mile delivery arrangements.
For one supported example, AAF states that its United States air operation has scheduled flights on Wednesday and Saturday. According to the company's official FAQ, these flights arrive at the destination port on the day after departure. This describes the air-transport stage only and should not be interpreted as next-day delivery to the final recipient, because customs clearance and domestic delivery still follow.
For ocean freight, AAF states that it uses direct sailings on routes serving countries including the United States, Canada, Japan, United Kingdom, Germany and France and selects among shipping schedules according to customer requirements. The company does not publish one fixed number of days for all of these sea routes, so delivery estimates should be obtained for the specific shipment.
AAF also advertises international trucking with daily departures on supported routes, but again does not give one universal end-to-end transit time. Customs inspections, port congestion, flight or vessel schedules, destination warehouse processing and the selected last-mile carrier can all affect the final delivery date.
How to contact AAF about shipment issues
If your Tracking has stopped updating or you need help with an AAF shipment, the company's official Shenzhen headquarters contact page lists the hotline 19928715441. AAF states that the same number can also be used through WeChat. Its headquarters is located in Longgang District, Shenzhen, and the official website lists addresses for its domestic and international branches.
When requesting support, provide the complete shipment reference, destination, shipping method and latest package tracking event. If a second tracking number has been assigned by FedEx, UPS or another final-mile carrier, include that number as well because it can help identify which part of the journey is experiencing the delay.
For damaged shipments, AAF's official guidance says that an abnormality discovered after delivery should be reported to the local delivery service provider within 7 days. Customers should obtain the local case or acceptance number and retain evidence such as photographs of the inner and outer packaging, photographs showing the damage, affected quantity, weight and declared value for the investigation.
If you are the recipient of an online purchase rather than AAF's direct shipping customer, contacting the seller or sender is also useful. AAF primarily provides cross-border first-mile and business logistics services, so the seller may have the booking information, AAF reference and last-mile tracking number required to request an investigation.
Frequently asked questions about AAF package tracking issues
How can I Track an AAF package?
Enter the shipment number on 4Tracking, allow the carrier to be detected or select AAF, and press the Track button. The results page will display the available AAF package tracking events and current shipment status.
What does an AAF tracking number look like?
AAF does not publish one universal format for all tracking numbers. Its services cover different transportation modes and may use different shipment references, so enter the complete identifier provided with your shipment rather than assuming a particular number of digits or letters.
Why did I receive a second tracking number for my AAF shipment?
AAF can transfer cargo to a destination carrier for final delivery. For example, its official information confirms that FedEx tracking numbers can be generated for relevant United States air shipments. The second number can therefore represent the last-mile portion of the journey.
Why does my FedEx number from AAF show no Tracking yet?
AAF states that a FedEx tracking number can be generated after cargo is delivered to AAF, but movement on the FedEx system becomes searchable after United States customs clearance. An inactive FedEx number before that stage does not necessarily mean that the international shipment has stopped moving.
How long does AAF delivery take?
There is no single transit time for all AAF shipments. Air, sea and road products have different schedules, and customs clearance plus final delivery add additional time. For United States air freight, AAF provides one specific example: scheduled departures are on Wednesday and Saturday, with arrival at the destination port the following day after takeoff.
Does next-day arrival for AAF United States air freight mean next-day package delivery?
No. AAF's next-day statement refers to arrival at the destination port after the scheduled flight departs. Customs clearance, handover to the domestic carrier and final delivery occur afterward.
Where does AAF have its own branches?
AAF officially lists operations in China and overseas branches in the United States, United Kingdom, Belgium, France, Germany, Canada, Japan, Mexico, Kazakhstan, Vietnam, Peru, Australia, Belarus, Ecuador and Guatemala. It can serve additional destinations through its wider transportation and logistics network.
Why has my AAF package tracking stopped updating?
A gap can occur while cargo is in international transit, awaiting customs clearance or being transferred to a last-mile provider. Check whether another tracking number has been issued. If the shipment remains unchanged unexpectedly, contact AAF or the sender with all available shipment references.
What should I do if my AAF shipment arrives damaged?
AAF advises reporting delivery damage to the local service provider within 7 days and obtaining a local case number. Keep photographs of the external and internal packaging, detailed photographs of the damage, quantity, weight and declared value so the shipment can be investigated.
How do I contact AAF about a delayed shipment?
AAF's official headquarters hotline is 19928715441, and the same number is listed for WeChat. Provide your shipment reference, destination, transportation method and any final-mile tracking number when requesting assistance.
