Enter your UniUni tracking number on Ship24 to check the latest package status, recent scans, and delivery progress in one place. Ship24 is useful when your order may involve UniUni for last-mile delivery and another courier, marketplace, or cross-border shipping partner earlier in the route. You can also track directly on the official UniUni tracking page or check the order page from the seller that shipped your parcel.
What is UniUni?
UniUni is a last-mile delivery company serving eCommerce shipments in Canada and the United States. It is often used after a seller, marketplace, warehouse, or cross-border shipping partner prepares the parcel and passes it into a local delivery network.
For shoppers, this means UniUni tracking usually becomes most useful once the parcel has been received and scanned by UniUni. If your tracking number exists but has no ETA yet, the seller may still be processing the order or waiting to hand the package to UniUni.
How do I track a UniUni package?
You can track a UniUni package through Ship24, the official UniUni tracking page, your seller or marketplace account, or UniUni support if you need help with a delivery issue.
Track your UniUni package on Ship24
- Enter your UniUni tracking number in the search field at the top of this page.
- Click the search button to start tracking.
Ship24 can help when your UniUni package is part of a wider shipping route. For example, your parcel may move through another postal or logistics provider before UniUni handles final delivery. You can also track other couriers on Ship24, such as Canada Post, USPS, and China Post.
Track on the UniUni website
- Go to UniUni's tracking page.
- Enter your UniUni tracking number.
- If requested, enter the destination postal code used on the order.
- Click the "Track" button to view the latest update.
Tip: UniUni’s tracking page allows up to 25 tracking numbers at once, separated by commas. If a result does not appear, check the number for missing characters or extra spaces. You can also read Ship24’s guide on what to do when a parcel cannot be found.
Track through the seller or marketplace
If your UniUni tracking number came from an online store or marketplace, check your order details page as well. Sellers may show order processing, dispatch, and handover updates before UniUni receives the parcel. If you only have an order number, contact the seller and ask for the carrier tracking number.
UniUni tracking number format
A UniUni tracking number identifies your parcel in UniUni’s tracking system. Based on common UniUni examples, the number often starts with UUS followed by letters and numbers.
- Usually starts with UUS
- Often contains 19 characters in total
- Can use numbers only after the prefix, or a mix of letters and numbers
Examples include UUS6181780830420033, UUS6160850813853827, UUS6151780805221048, and UUS5CS1789743195995.
Where can I find my UniUni tracking number?
- Shipping confirmation email: Look for the tracking link or carrier tracking number sent after dispatch.
- Marketplace order page: Open your order details and check the delivery or logistics section.
- SMS or app notification: Some stores send the tracking number by message after the parcel is shipped.
- Seller support: Ask the seller for the UniUni tracking number if you only have an order ID.

Understanding UniUni tracking statuses
UniUni tracking statuses show where your parcel is in the delivery process. Some shipments may show fewer scans than others, especially during facility transfers, cross-border handovers, or busy delivery periods.
| Status | Meaning |
|---|---|
| Order received | The shipment information has been created or received. The parcel may still be with the seller and may not have been handed to UniUni yet. |
| Gateway transit in | The package has arrived at a gateway, facility, or sorting point for processing. |
| Gateway transit out | The package has left a gateway or facility and is moving to the next stage of the route. |
| In Transit to Next Facility | The parcel is moving between UniUni facilities, sorting centres, or delivery areas. |
| Arrival scan | The package has arrived at a facility, warehouse, or local delivery station and has been scanned there. |
| Out for delivery | The parcel has been assigned to a driver and is expected to arrive soon. |
| Delivered | The package has been marked as delivered to the recipient, address, mailbox, parcel room, reception area, or another delivery location. |
Typical UniUni status progression
- Order received
- Gateway transit in
- Gateway transit out
- In Transit to Next Facility
- Arrival scan
- Out for delivery
- Delivered
Not every package follows this exact order. Some scans may be skipped or delayed depending on the route, local facility, seller handover, delivery volume, weather, or access issues.
Why is my UniUni tracking not updating?
If your UniUni tracking number has no update yet, the seller may still be preparing the parcel. UniUni says it can only provide an accurate ETA once it has received the parcel from the vendor. In this case, check your seller or marketplace account for the latest order processing status.
If UniUni has already received the parcel but the status has not changed for several days, the package may be moving between facilities, waiting for its next scan, or affected by local delivery conditions. Re-enter the tracking number, check whether a postal code is required, and contact the seller or UniUni support if the delay continues.
UniUni tracking issues and what to do
| Issue | What it may mean | Next step |
|---|---|---|
| Tracking number not found | The number may be incorrect, inactive, or not yet scanned by UniUni. | Check the code, remove extra spaces, and confirm the tracking number with the seller. |
| No ETA shown | UniUni may not have received the parcel yet. | Check the seller’s order page or contact the seller for handover status. |
| Postal code not accepted | The postal code may not match the destination address on the shipment. | Use the postal code from your order confirmation and check for typing errors. |
| Delivered but not received | The parcel may have been left at a mailbox, parcel room, front desk, neighbour, or another approved location. | Check nearby delivery spots, then contact UniUni support if the package is still missing. You can also read Ship24’s guide on what to do when a package is delivered but not received. |
| Failed delivery attempt | The driver may not have been able to access the address or complete delivery. | Check your address, unit number, phone number, gate code, and delivery instructions. |
What happens if UniUni delivery fails?
If the first delivery attempt fails, UniUni says its driver will automatically reattempt delivery within 24 to 48 hours. A failed attempt can happen when the address, phone number, unit number, gate code, or delivery instructions are missing or incorrect.
If the second delivery attempt fails, the parcel may be taken back to the warehouse. Once the parcel shows Storage status, submit a support ticket through UniUni support to arrange another delivery. UniUni also says delivery attempts may be rejected for PO Box addresses or incorrect addresses.
Can I update my UniUni delivery information?
Yes. UniUni allows delivery information updates through its support ticket form. You can request changes or additions to your unit number, gate or buzz code, phone number, or delivery instructions.
- Go to UniUni's support page.
- Submit a support ticket.
- Add your tracking number and explain what information needs to be updated.
- Wait for UniUni support to confirm the change.
Send changes as early as possible. Once a parcel is already out for delivery, the driver may not receive the update in time.
How long does UniUni take to deliver?
UniUni delivery time depends on the seller’s processing time, shipping service, destination, local facility capacity, and whether the parcel is domestic or cross-border. UniUni states that delivery services across the U.S. and Canada can range from next-day delivery to up to 7 days.
Tracking is the best way to check your parcel-specific timeframe. If the shipment has no ETA, UniUni may not have received it yet. If the tracking shows movement but delivery is delayed, check for facility scans, weather alerts, or failed delivery messages.
Recent UniUni updates that may affect tracking
UniUni has continued to invest in its last-mile delivery network and technology. In 2026, the company announced an Enveyo integration covering label generation, order management, shipment tracking, and last-mile performance visibility. UniUni also announced new funding to support sorting machines, warehouse operations, parcel throughput, and expansion across the U.S. and Canada.
These updates may support wider coverage and parcel processing capacity, but they do not mean every tracking event will update faster. Tracking speed still depends on scans, handover timing, facility processing, route conditions, and local delivery access.
Contacting UniUni customer support
Contact UniUni support if your parcel is overdue, marked delivered but missing, stuck after UniUni received it, or showing a failed delivery or Storage status. The support form includes request categories such as address correction, delivery inquiry, lost parcel, second delivery, proof of delivery request, and delivery instruction updates.
Before contacting support, prepare your tracking number, destination postal code, full address, phone number, access instructions, and a short explanation of the issue.
If you are not sure whether the courier or seller should handle the issue, read Ship24’s guide on how to contact the courier for lost or damaged packages.
