How Does PostNL / Cainiao Work with AliExpress Deliveries in the UK?

AliExpress Shipping Methods: Understanding Cainiao and PostNL
AliExpress offers a variety of shipping methods for UK buyers, and two of the most common logistics providers you’ll encounter are Cainiao and PostNL. Many shoppers ask, Does AliExpress use Cainiao? Yes, Cainiao is the official logistics arm of the Alibaba Group, which owns AliExpress. It manages international shipping for millions of parcels, often in collaboration with local and international postal partners like PostNL.
When you order on AliExpress, you might notice shipping options such as AliExpress Standard Shipping, Cainiao Standard for Special Goods, or AliExpress Saver Shipping. These often rely on Cainiao’s logistics network to move parcels from China to the UK, sometimes using PostNL as a carrier for part of the journey.
What Delivery Company Does AliExpress Use?
What delivery company does AliExpress use? AliExpress partners with a range of global and local delivery companies to get your order to your door in the UK. The main companies involved in handling AliExpress parcels for UK buyers include:
- Cainiao (for international logistics and tracking)
- PostNL (Dutch postal service, often handles parcels in Europe)
- Royal Mail (handles last-mile delivery for many AliExpress orders in the UK)
- Other couriers, depending on the chosen shipping method and parcel size
If you select a shipping method like AliExpress Standard Shipping or Cainiao Standard, your parcel will likely be routed through Cainiao’s network, possibly handled by PostNL in the Netherlands, and then delivered by Royal Mail or another UK courier.
Cainiao: The Backbone of AliExpress Shipping
What Delivery Service Does Cainiao Use?
What delivery service does Cainiao use? Cainiao is not a courier in itself, but rather a logistics platform that partners with airlines, customs, and local postal services worldwide. For UK deliveries, Cainiao typically works with:
- PostNL for European transit and customs clearance
- Royal Mail for final delivery to your UK address
- Other local couriers, depending on the parcel type (e.g., Yodel, Hermes/Evri)
Cainiao selects the most efficient route and local partners based on your address, the seller’s location, and the shipping method you choose at checkout.
Cainiao Heavy Parcel Tracking and Local Delivery Companies
For larger or heavier items, you might see references to Cainiao Heavy Parcel tracking or Cainiao local delivery company in your tracking information. These terms indicate that Cainiao has partnered with a specific courier experienced in handling bulkier shipments. In the UK, these are usually delivered by Royal Mail Parcelforce or other specialist couriers.
You can track these parcels using the Cainiao website or third-party services like 17TRACK for detailed status updates.
PostNL: The Dutch Postal Service in AliExpress Shipping
Who Delivers for PostNL?
Who delivers for PostNL? PostNL is the national postal service of the Netherlands. In the context of AliExpress, PostNL acts as a key transit partner for parcels coming from China to Europe. Once your parcel arrives in the Netherlands, PostNL handles customs clearance and forwards the package to the UK.
But PostNL itself does not deliver directly to your UK address. Instead, after processing, PostNL hands over the parcel to Royal Mail or another local courier for final delivery.
Who Delivers Cainiao in the UK?
Who delivers Cainiao in the UK? In almost all cases, Royal Mail is responsible for delivering Cainiao parcels once they reach the UK. For larger or tracked items, Parcelforce (a Royal Mail company) or other couriers such as Hermes/Evri or Yodel may be used, depending on the parcel’s size and the delivery service selected.
- Standard letters and small parcels: Delivered by Royal Mail
- Bulky or heavy parcels: Delivered by Parcelforce or other specialist couriers
PostNL AliExpress and Reddit Discussions
Many UK buyers search for PostNL AliExpress reddit to read about others’ experiences. Common themes include tracking updates, customs delays, and delivery times. Most users report that PostNL is reliable for forwarding parcels to the UK, but tracking can sometimes be confusing due to multiple handovers between carriers.
If you’re concerned about your parcel, it’s a good idea to check tracking updates on both the AliExpress order page and third-party tracking sites.
Tracking Your AliExpress Order: Cainiao, PostNL, Royal Mail, and More
What Tracking Does AliExpress Use?
What tracking does AliExpress use? AliExpress provides tracking numbers for most shipments, especially those sent by AliExpress Standard Shipping or Cainiao Standard. The tracking number format may change as the parcel moves between carriers.
You can use several platforms to track your order:
- AliExpress Order Page: Basic tracking updates and estimated delivery window
- Cainiao Tracking: (global.cainiao.com) for detailed journey information
- PostNL Tracking: (postnl.nl/en/track-trace) for updates once the parcel is handled by PostNL
- Royal Mail Tracking: (royalmail.com/track-your-item) for final delivery status in the UK
- 17TRACK: (17track.net) to track parcels across multiple carriers with a single tracking number
If you see Aliexpress NL tracking number in your order details, this means your parcel is being routed through the Netherlands (NL) and handled by PostNL before coming to the UK.
How to Use 17TRACK for AliExpress Orders
17TRACK is a popular global parcel tracking platform that allows you to enter your AliExpress tracking number and see updates from Cainiao, PostNL, Royal Mail, and other couriers all in one place. This is especially helpful if your parcel is moving between multiple countries and carriers.
To track your AliExpress order on 17TRACK:
- Copy the tracking number from your AliExpress order page
- Go to 17track.net
- Paste your tracking number and click “Track”
- View the parcel’s journey, including updates from Cainiao, PostNL, and Royal Mail
PostNL Tracking for AliExpress Parcels
If your parcel is being handled by PostNL, you can use the PostNL tracking tool to get more detailed updates while your parcel is in the Netherlands or in transit to the UK. Simply enter your tracking number on the PostNL tracking page.
Keep in mind that once the parcel leaves the Netherlands and is handed over to Royal Mail, the tracking number may change or require you to use Royal Mail’s system for further updates.

Royal Mail Tracking for AliExpress Deliveries
Once your parcel arrives in the UK, Royal Mail tracking becomes the best resource for delivery updates. Use your tracking number (sometimes the same as your PostNL or Cainiao number) on the Royal Mail tracking page to check delivery status, expected arrival, or if a delivery attempt has been made.
For parcels sent via Parcelforce, use their dedicated tracking system for more detailed information on heavy or bulky items.
AliExpress NL Tracking Number: What Does It Mean?
You may notice your AliExpress order is assigned an AliExpress NL tracking number. This indicates your parcel is being shipped via the Netherlands (NL) as a transit country. The parcel is first sent from China to the Netherlands, processed by PostNL, and then forwarded to the UK for final delivery.
This route is commonly used for AliExpress Standard Shipping and Cainiao Standard parcels, as it allows for efficient customs clearance and reliable onward shipping to the UK.
Tip: If your tracking number starts with “NL” or contains “NL” in the middle, you can use both PostNL tracking and 17TRACK to monitor your parcel’s progress.
How the AliExpress, Cainiao, and PostNL Delivery Chain Works
Step-by-Step: From Seller to Your Door
- Seller Dispatches Parcel: The AliExpress seller hands your order to a local courier or directly to Cainiao’s logistics hub in China.
- Cainiao Handles Export: Cainiao coordinates export, often aggregating parcels for bulk shipment to Europe.
- Arrival in the Netherlands: Parcels arrive in the Netherlands, where PostNL manages customs clearance and re-labels the parcel for onward travel.
- Parcel Sent to the UK: PostNL forwards the parcel to the UK, handing it over to Royal Mail or another local delivery company.
- Final Delivery: Royal Mail delivers the parcel to your address, or leaves a collection card if you’re not home.
Tracking Your Parcel at Every Stage
At each stage, your tracking number will provide updates. Use Cainiao tracking for the early stages, PostNL tracking for the European leg, and Royal Mail tracking for final delivery in the UK. 17TRACK is especially useful for seeing all updates in one place.
Common Questions from UK Buyers About AliExpress, Cainiao, and PostNL
Why Does My AliExpress Tracking Seem Stuck?
It’s common for tracking to pause for several days while your parcel is in transit between countries or waiting for customs clearance. If your PostNL AliExpress tracking hasn’t updated, it may be awaiting a flight or processing at a sorting centre. Use 17TRACK to check if another carrier has new updates.
How Long Does AliExpress Delivery Take to the UK?
Delivery times vary, but most AliExpress Standard Shipping parcels arrive in the UK within 10-25 business days. Delays can occur due to customs, busy seasons, or disruptions in international shipping. Cainiao and PostNL work together to keep parcels moving, but final delivery depends on Royal Mail or your local courier.
If your parcel hasn’t arrived after 30 days, check tracking and contact the seller via AliExpress.
What Should I Do If My Parcel Is Lost or Delayed?
If your parcel tracking shows no updates for more than two weeks, or if it’s marked as delivered but you haven’t received it, you should:
- Contact the seller through AliExpress messages
- Open a dispute on AliExpress if the estimated delivery date has passed
- Check with Royal Mail using your tracking number
- Ask your local sorting office if they are holding the parcel
AliExpress buyer protection covers you for non-delivery or lost items, so you can request a refund if your order doesn’t arrive.
Is There a Way to Speed Up AliExpress Delivery?
Faster shipping options such as AliExpress Premium Shipping or DHL/FedEx are available at a higher cost. These services bypass Cainiao and PostNL, going directly to premium couriers. For standard orders, choosing AliExpress Standard Shipping (Cainiao/PostNL) offers a good balance of cost and reliability for UK buyers.

Tips for UK Buyers Using AliExpress, Cainiao, and PostNL
- Always check the estimated delivery date on your AliExpress order page
- Use 17TRACK or Cainiao tracking for real-time updates across carriers
- Monitor PostNL and Royal Mail tracking when your parcel is in Europe or the UK
