ZLS, also known as Zhongtong Logistics, is one of China's largest express delivery networks. Founded in 2002, the company operates as a backbone logistics provider for e-commerce sellers, small businesses, and individual shippers across mainland China. ZLS handles millions of parcels daily, moving packages through a nationwide network of distribution centers and last-mile delivery partners. The carrier is particularly popular for cost-effective domestic shipping and increasingly for cross-border parcels heading to Southeast Asia and beyond.
ZLS provides multiple shipping options tailored to different sender needs. Their standard express service covers urban and rural areas across China with typical delivery windows of 2-5 business days depending on distance. The company also offers specialized services including signature-required delivery, temperature-controlled logistics for sensitive goods, and bulk shipping discounts for high-volume merchants. ZLS has expanded into international logistics, with dedicated routes to major Southeast Asian countries and growing partnerships for US and European deliveries.
When you add a ZLS tracking number to Paxlo, the app connects directly to ZLS's tracking database. You'll see every scan and status update as your package moves through their system, from initial pickup at the sender's location through sorting hubs, regional distribution centers, and final delivery. Paxlo translates all Chinese status descriptions into your preferred language so you understand exactly where your parcel is and when to expect it.
The integration goes beyond basic tracking. Paxlo analyzes ZLS's handling patterns, typical transit times, and delivery day estimates based on your package's specific route and origin city. If a shipment shows delays or unusual activity, you'll get an alert before it becomes a real problem. For international ZLS shipments, Paxlo tracks handoffs to other carriers and explains what each status means as your parcel crosses borders.
ZLS's official tracking website operates primarily in Chinese, and the interface isn't designed for quick mobile lookups. You'd need to copy and paste tracking numbers, wait for page loads, and interpret Chinese status messages. Paxlo solves all of this. Add your ZLS tracking number once, and get automatic push notifications when your package status changes. No logging in repeatedly, no language barriers, no delays.
Most ZLS domestic shipments within China arrive within the quoted timeframe, especially for routes between major cities like Beijing, Shanghai, and Guangzhou. However, packages heading to rural areas or during peak seasons (Chinese New Year, Singles' Day) can experience delays. Paxlo flags these high-risk scenarios early so you're not surprised. If you've ordered from a Chinese online retailer and received a ZLS tracking number, Paxlo will update you the moment it ships until it reaches your door.
For international ZLS shipments, watch for a handoff point where ZLS passes your package to a local carrier in the destination country. Paxlo will highlight this transition so you know to expect a new tracking number or a pause in updates. This is normal and not a sign of trouble, though Paxlo will keep you informed throughout the handoff period.
ZLS has earned its position as a major carrier through consistent on-time delivery and a vast infrastructure. The company invests heavily in automation and sorting technology, which keeps costs down and speeds up processing. Because ZLS handles such high volumes, occasional hiccups do happen, packages can get stuck in high-traffic hubs, or last-mile delivery can slip a day. Paxlo's real-time monitoring catches these issues and alerts you immediately so you can follow up with the seller or carrier if needed.
By using Paxlo to track ZLS shipments, you gain visibility and peace of mind. You're not left wondering if your package is lost, delayed, or simply slow to update. The app delivers the information you need to make informed decisions about contacting customer service or filing a claim if something goes wrong.
Open Paxlo on your phone and tap the plus or add button. Paste or type your ZLS tracking number (usually a 13-digit code) and select ZLS from the carrier dropdown. If you're not sure whether it's a ZLS shipment, Paxlo can often auto-detect the carrier from the tracking number format. Tap confirm, and your package will start tracking immediately. Most updates appear within minutes of ZLS scanning your parcel at their facilities.
ZLS packages typically pause at regional sorting hubs for 6 to 24 hours while staff scan and redistribute parcels by next destination. This is completely normal. However, if your package has been sitting in the same location for more than 48 hours without movement, contact the seller or ZLS customer service. Paxlo will send you an alert if it detects an unusual delay, helping you catch problems early before they become lost packages.
Yes. Paxlo supports ZLS's international tracking and will follow your package from China to its destination country. You may see a gap in tracking information when ZLS hands off to a local carrier abroad, this is normal. Sometimes the receiving carrier will issue a new tracking number, other times ZLS's number stays active. Paxlo handles both scenarios and will clarify the handoff point so you know what to expect.
In transit means your parcel is moving between ZLS facilities, either on a truck, in a warehouse, or at a local delivery station. It could also mean it's been picked up and en route to the first sorting hub. The status will eventually become more specific, like 'out for delivery' when the package is on the delivery driver's route. Paxlo provides estimated delivery dates based on where the package is in the transit cycle, so you'll know roughly when to expect it even during the 'in transit' phase.
Download Paxlo and track all your packages in one place. Free, fast, and trusted by 50,000+ users worldwide.
First check Paxlo for the latest status update. If the package is still in transit and moving, wait another 2 to 3 days, especially if it's headed to a remote area. If tracking shows no movement for 2+ days or shows 'failed delivery' attempts, contact the seller or ZLS customer service right away. Provide them with your tracking number and let them know you're following it via Paxlo. In China, ZLS typically responds to inquiries within 24 hours. If the package is genuinely lost, the seller or shipper can file a claim with ZLS.
