LTIAN EXP is the tracking name associated with Letian International Express (乐天国际速递), a China-based cross-border logistics provider established in 1997. The company focuses on e-commerce parcels, commercial express shipments and international logistics solutions for Chinese merchants sending goods to overseas customers.
The company operates processing centers in Shanghai, Qingdao and Shenzhen and has developed overseas warehousing and logistics resources in the United States and Canada. Its service portfolio includes dedicated North American routes, South American routes, international postal products, commercial express services, consolidation and forwarding, overseas warehousing and return handling.
LTIAN EXP works with destination postal and courier networks to complete international deliveries. Official service information identifies partners such as USPS, FedEx and DHL in the United States, Canada Post in Canada and Correios in Brazil. Some products use direct or commercial flights from China or Hong Kong before transferring the package to a destination carrier.
The company also provides online ordering and API integration for merchants. When an order is created, its system can generate a logistics number for the selected shipping channel, and supported services provide end-to-end shipment visibility. This makes package tracking useful for following a parcel from processing in China through international transportation and onward delivery.
How LTIAN EXP shipment tracking works
LTIAN EXP provides an official Tracking page where customers can enter shipment numbers and retrieve available logistics events. The tracking interface supports up to 30 tracking numbers at one time, with multiple numbers entered on separate lines.
The company's official API also supports retrieving tracking numbers and detailed shipment records. Tracking information can include the destination country, shipment status, event date, location and event description. Published API examples include events such as item information received, item accepted and item outbound from a sorting center.
How to Track LTIAN EXP packages with 4Tracking
To Track a LTIAN EXP package with 4Tracking, enter the tracking number in the tracking field. Select LTIAN EXP from the carrier list if necessary, or allow 4Tracking to identify the carrier automatically, then press the Track button. You will be redirected to the results page, where available package tracking events can be followed in chronological order.
If no Tracking information appears immediately, verify that you entered the logistics tracking number rather than the merchant's internal order reference. A newly created shipment can also have an electronic record before the physical parcel receives its first operational scan.
LTIAN EXP tracking number formats
LTIAN EXP does not publish one universal tracking-number format for every shipping channel. Its system can maintain a customer reference number, a service-provider tracking number and a channel transfer number, so the identifier used for package tracking can depend on the selected logistics product.
Official tracking-number examples
The official LTIAN EXP API documentation contains service-provider tracking-number examples such as RZ000013260TW and RZ000013256TW. These examples begin with RZ, contain digits and end with TW, but they are examples from the documented API and should not be treated as the required format for every LTIAN EXP shipment.
Because different services can use destination postal or courier partners, another tracking number may also be assigned during the shipment journey. Keep both the original LTIAN EXP number and any partner-carrier number that appears because the latter can become useful during final delivery.
LTIAN EXP delivery times and supported examples
LTIAN EXP does not have one delivery-time promise covering every shipment. Transit depends on the selected product, destination, flight or transport schedule, customs processing and final-mile carrier. Its official service pages publish separate reference times for individual routes.
United States USPS Express example
The official US USPS Express service lists a reference transit time of approximately 5-8 working days. The service uses priority warehouse processing and flight arrangements, enters the United States through ports including New York, Chicago, Los Angeles, Miami and Houston, and can be tracked through delivery.
United States Economy Line example
LTIAN EXP's US Economy Line, which uses DHL and FedEx services, publishes a reference time of approximately 8-12 working days. The official product page describes it as an economical US route with Tracking available through final delivery.
Global ePack example
The ePack Global service publishes a reference transit time of approximately 7-15 working days. Parcels depart from Hong Kong or Shanghai on commercial flights, pass through a USPS international transfer process in New York and are then delivered by the postal operator in the destination country. The service is described as fully Trackable.
Brazil service examples
For Brazil, LTIAN EXP lists approximately 5-8 working days for its Correios Express product and approximately 8-12 working days for its Correios Standard product. These estimates belong to those specific services and should not be applied to every LTIAN EXP shipment.
How to contact LTIAN EXP about shipment issues
LTIAN EXP lists the customer-service phone number 800-820-3585. Its official contact page also lists 13501680044 as a customer-service and WeChat number.
For complaints and suggestions, the official email address is gongxie@ltexp.com.cn. The company's published address is Room 1002, Building B, Xinghui Center, No. 88 Sichuan North Road, Shanghai, China. The official contact page lists working hours of 10:00 AM to 5:00 PM.
If your LTIAN EXP package was purchased from an online marketplace or independent seller, contacting the sender is also recommended. The merchant created the shipment and may have access to the selected route, customer reference number and account information needed to request a logistics investigation.
Frequently asked questions about LTIAN EXP package tracking issues
Why is my LTIAN EXP tracking number not working?
Check that you entered the actual logistics tracking number rather than the merchant's internal order number. A recently created shipment may initially have only electronic shipment information and may not display additional Tracking events until the parcel is physically accepted.
What format does a LTIAN EXP tracking number use?
There is no single published format covering every LTIAN EXP shipping channel. The official API contains examples such as RZ000013260TW, but different products and partner carriers can use other tracking-number structures.
Can I Track several LTIAN EXP packages at once?
Yes. The official LTIAN EXP Tracking page states that up to 30 shipment numbers can be queried at one time by entering multiple numbers on separate lines.
Why has my LTIAN EXP package tracking stopped updating?
International parcels can move between major logistics checkpoints without receiving a new public scan. Flight transportation, customs processing and handover to a destination postal or courier network can all produce temporary gaps between Tracking events.
How long does LTIAN EXP take to deliver to the United States?
Delivery depends on the selected service. The official USPS Express route lists approximately 5-8 working days, while the US Economy Line lists approximately 8-12 working days. These are route-specific reference times rather than universal guarantees.
Does LTIAN EXP provide worldwide parcel services?
Yes. The company describes its services as reaching destinations worldwide and offers products including global ePack, international postal services, commercial express delivery, dedicated regional routes and consolidation services.
Why does another carrier appear during LTIAN EXP Tracking?
This is normal for many LTIAN EXP services. The company works with destination carriers such as USPS, FedEx, DHL, Canada Post and Correios. A partner carrier may therefore handle the package after international transportation and provide additional Tracking events.
What should I do if my LTIAN EXP package is delayed?
Check the latest package tracking event and compare it with the reference time for the specific shipping service. If the shipment has exceeded the expected period without meaningful progress, contact the seller or call LTIAN EXP at 800-820-3585 or 13501680044, or email gongxie@ltexp.com.cn.
What should I do if LTIAN EXP Tracking says delivered but I did not receive the package?
Check the delivery location, household members, reception staff and any final-mile carrier shown in the Tracking history. If USPS, FedEx, DHL or another destination carrier completed delivery, review its delivery information as well. If the parcel still cannot be located, contact the seller and LTIAN EXP with the tracking number and final delivery status so the shipment can be investigated.
