ACS Worldwide Express is one of China's leading international parcel delivery providers, headquartered in Beijing. Since its founding, the company has grown to serve millions of shipments annually across more than 220 countries and territories. ACS specializes in cross-border logistics, handling everything from small parcels to heavier packages that need reliable international transport. The carrier operates its own network of sorting facilities, distribution centers, and partner relationships worldwide, making it a go-to choice for Chinese e-commerce sellers and individual shippers.
China's logistics sector has exploded over the past two decades, driven by booming e-commerce platforms and global trade. ACS Worldwide Express emerged to fill a critical gap, offering affordable international shipping when major carriers were expensive or unavailable to certain regions. The company holds key licenses for international express services and maintains partnerships with local and global carriers. This strategic positioning makes ACS essential infrastructure for small businesses, online sellers, and individual customers who need to send packages globally without breaking their budgets. Today, ACS handles roughly 500 million parcels per year, serving as a backbone for cross-border commerce in Asia.
Paxlo connects directly to ACS Worldwide Express's tracking system, giving you live visibility the moment your package is scanned at their facility. Once you add your tracking number to Paxlo, the app pulls real-time updates showing every movement through ACS's network, from the China origin to your destination country. You'll see timestamp details, facility locations, and status changes without hunting through different websites or translation pages.
The app handles the complexity of international tracking automatically. ACS hands off shipments to partner carriers at various international hubs. Paxlo tracks these handoffs and shows you which carrier currently holds your package. This matters because ACS often partners with local postal services in destination countries, and understanding that transition helps you predict delivery timing.
Delivery speed depends on your destination and the service tier chosen at shipment time. Standard International Express typically takes 15-30 days to developed countries (USA, Canada, Australia, Western Europe) and 20-45 days to developing regions. Special line services to major markets can be faster, sometimes reaching 10-15 days door-to-door. Paxlo's tracking shows you exactly where your package sits in this timeline, so you're never guessing whether it's stuck or right on schedule.
Customs clearance is the biggest variable. Packages bound for the US, UK, or EU may spend 3-7 days in customs inspection. Paxlo alerts you when this stage begins, so you know not to expect delivery until it clears. This transparency prevents the frustration of wondering if your package is lost when it's actually just sitting in a customs facility.
ACS shipments can experience delays for several reasons. Weather disruptions, particularly monsoon season affecting Southeast Asia, occasionally slow flights. Customs holds happen frequently when declaration values seem inconsistent with package contents. Paxlo's tracking updates tell you exactly which stage the delay occurred at, so you know whether to contact ACS about a logistics issue or wait out customs clearance.
If a package shows no movement for 10+ days at a single facility, that's a red flag worth investigating. Paxlo lets you flag stuck shipments and access your tracking history to share with ACS customer support. The app also stores all your past ACS tracking numbers, so you can look up patterns if you ship regularly.
ACS delivers to over 220 territories, including remote islands and developing nations where major carriers charge premium rates. This global footprint makes ACS popular for online sellers serving diverse customer bases. The carrier operates with reasonable reliability, though performance varies by destination. Packages heading to established markets like the USA or UK typically arrive on schedule. Shipments to less-developed regions may take longer, partly due to local postal infrastructure limitations.
Paxlo's tracking data aggregates thousands of ACS shipments, giving you realistic expectations for your specific route. If your package is heading to a destination with historically slower delivery, Paxlo sets your expectations accordingly rather than promising arrival dates that rarely materialize.
When you track an ACS shipment with Paxlo, you unlock the full app ecosystem. Set delivery date alerts so you're not home when the package arrives. Share tracking links with friends or family members so they can check status without needing the tracking number. Create wishlists from items you've tracked before, streamlining reorders. Use Paxlo's package value logging to track spending across international purchases.
Paxlo also learns from your tracking history. If you notice that ACS packages from a particular seller always ship via a slower route, Paxlo flags that pattern. Over time, the app becomes smarter about predicting your delivery windows and highlighting when something seems off.
Open the Paxlo app and tap the plus icon to add a new shipment. Paste your ACS tracking number (usually a 13-digit number starting with an 'S') into the search field. Paxlo automatically identifies it as an ACS shipment and connects to their live tracking system. You'll see a timeline of all scans from pickup through delivery, along with the facility locations and estimated delivery date. Enable push notifications so Paxlo alerts you whenever your package status changes.
ACS tracking numbers can take 24-48 hours to appear in their system after you hand off the package. If your tracking number still shows no data after two days, double-check that you entered it correctly. ACS uses strict formatting, so even one digit off will return no results. If the number is correct and you still see no data, contact your ACS shipper or the seller who sent you the package. Sometimes the number gets printed on the label but isn't activated in their system immediately.
When Paxlo shows this status, your package has arrived at the destination country's customs facility and is waiting for inspection. This typically takes 3-7 days in most countries. Customs may request additional documentation if the declared value seems incorrect or the contents are uncertain. If you're the recipient and customs requests information, you should receive a notification from the customs authority directly, not from ACS or Paxlo. Don't panic if this stage takes longer than expected, especially during peak holiday shipping periods.
Paxlo's interface lets you view all tracking data and set up alerts, but direct messaging with ACS isn't available through the app. However, Paxlo stores your complete tracking history, which you can screenshot or export to share with ACS customer support if you need to report a problem. Having this detailed tracking timeline helps ACS investigate lost or delayed packages faster. For urgent issues, contact ACS directly through their website with your tracking number and detailed explanation of the problem.

Standard ACS Worldwide Express shipments take 15-30 days to most developed countries (USA, Canada, Australia, Western Europe) and 20-45 days to other regions. The timeline depends on your destination country, the service tier you paid for, and current customs processing times. Paxlo shows your package's specific estimated delivery date based on its current location and the route it's taking. Keep in mind that customs delays can add several days, and these aren't always predictable. Tracking with Paxlo gives you live visibility rather than relying on generic timeframes.
First, check Paxlo to see exactly which facility your package is at. If it's stuck at a customs facility, delays are normal and can stretch to 7-10 days depending on the country. If it's stuck at an ACS sorting facility with no forward movement after 7+ days, contact ACS support with your tracking number and ask for an investigation. Provide Paxlo's tracking screenshot showing when the package last moved. ACS typically responds within 3-5 business days. If you don't get a response or the package isn't located, escalate to your seller or use buyer protection through the platform where you purchased the item.
