UniUni is a technology-enabled last-mile delivery company focused on e-commerce shipments in Canada and the United States. Founded in Vancouver in 2019, the company works with e-commerce platforms, online retailers, brands, third-party logistics providers and other businesses that need parcel delivery to consumers across North America.
UniUni's core service is final-mile parcel delivery, supported by a flexible driver network, sorting facilities, technology-based route optimization and real-time shipment visibility. Its current network covers about 80% of Canada and 65% of the United States, with delivery operations reaching more than 500 cities across North America.
In addition to domestic delivery, UniUni operates a cross-border service from the United States to Canada. This service can manage the journey from first-mile pickup in the United States through customs clearance and final delivery to the Canadian recipient. UniUni also provides proof-of-delivery features and digital shipment information intended to give merchants and recipients greater visibility throughout the delivery process.
Recipients can Track a shipment directly through UniUni's online package tracker or use 4Tracking for convenient package tracking alongside shipments from other carriers. UniUni Tracking can provide delivery status, estimated delivery information once the carrier has physically received the parcel, and proof-of-delivery information for completed shipments when available.
How to Track UniUni packages
To Track a UniUni package on 4Tracking, enter the complete tracking number supplied by the merchant, seller or UniUni into the tracking field and start the search. When shipment information is available, 4Tracking displays the available Tracking events so you can follow the package as it moves through the UniUni delivery network.
UniUni also operates an official online package tracker. Its public tracking page allows customers to enter up to 25 tracking numbers at once, separated by commas. The carrier uses the tracking page to provide the latest package status and, after UniUni physically receives the shipment, an estimated delivery date.
If a tracking number exists but has no new information, UniUni explains that the merchant or seller may still be processing the order and may not yet have handed it to UniUni. In this situation, the carrier recommends contacting the merchant or seller for the latest order status. The estimated delivery date normally appears after the parcel has physically entered UniUni's network.
For delivered shipments, UniUni's tracking service can also provide proof-of-delivery photos when they are available. Customers can enter the tracking number, select the delivery-confirmation option and provide the postal or ZIP code associated with the shipment to view the available delivery evidence.
UniUni tracking number formats
UniUni's current shipping-platform documentation defines shipment tracking IDs generated through its platform as 19-character identifiers. One documented format begins with UR followed by 17 digits. For example, UniUni's official developer documentation uses UR06250000000000351 as a sample tracking ID.
The same official documentation also defines a batch tracking identifier beginning with URB followed by 16 digits, also producing a 19-character identifier. UniUni's Partner API therefore accepts the patterns UR plus 17 digits or URB plus 16 digits for shipments created through the documented platform.
These documented formats should not automatically be treated as the only identifiers that may ever appear on shipments created through merchants, logistics integrations or older UniUni systems. For reliable package tracking, use the complete number supplied with your shipment rather than changing it to match a particular example.
Merchant order numbers are different from tracking numbers. UniUni's current platform documentation, for example, separately identifies merchant-facing order numbers and shipment tracking IDs. If the number you received does not work in Tracking, confirm with the seller that you were given the actual UniUni tracking number rather than an order reference.
UniUni delivery times
UniUni states that its last-mile delivery network offers delivery speeds ranging from next-day delivery to as long as seven days, depending on the service, route and destination. This range describes the company's available delivery capabilities rather than a guarantee that every UniUni package will arrive within the same number of days.
For a supported service example, UniUni's Canadian shipping platform provides a Next Day service level described as priority delivery using the fastest available transit time. Canadian customers can also select Standard delivery, while publication-type shipments can qualify for a separate Publication service.
For shipments created through UniUni's United States platform, the documented service option includes Standard delivery. The actual transit time depends on the origin, destination and service available for that shipment, so recipients should use the estimated delivery date shown in Tracking once UniUni has received the parcel.
UniUni's U.S.-to-Canada cross-border service follows a different process from a purely domestic last-mile shipment. UniUni can manage first-mile pickup in the United States, customs clearance and final delivery in Canada, so border processing and shipment circumstances can affect the overall transit time. The carrier does not publish one fixed delivery-time promise that applies to every U.S.-to-Canada shipment.
What UniUni Tracking statuses can tell you
UniUni's tracking systems record shipment events as parcels progress through its network. Its current technical documentation includes stages associated with shipment creation, receipt by UniUni, transportation and final delivery, including an Out for Delivery status when a parcel has been assigned for its final delivery stage.
If Tracking has not updated shortly after an online order was placed, this can mean that the seller has generated shipment information but has not yet transferred the physical parcel to UniUni. Once UniUni receives the package, additional scans and an estimated delivery date can become available.
A Delivered status can be accompanied by proof-of-delivery information. UniUni promotes proof of delivery as part of its service and states that three photographs can be captured at drop-off. The public tracking service also allows recipients to access available delivery-confirmation photos after verifying the destination postal or ZIP code.
What happens if a UniUni delivery attempt fails?
UniUni states that when the first delivery attempt fails, another attempt will occur within 48 hours in most circumstances. The recipient normally does not need to take action unless the delivery address, access information, unit number, gate or buzzer code, phone number or other delivery instructions need to be corrected.
If the second attempt also fails, the parcel can be returned to a UniUni warehouse. Once Tracking shows the package in storage, the recipient can contact customer support to arrange re-delivery. UniUni states that parcels in this situation are stored in its warehouse for 30 days.
UniUni does not deliver to USPS PO Boxes or local post offices. A delivery attempt can therefore be rejected when a USPS PO Box was supplied as the address or when the delivery address is incorrect. Customers who need to correct an address or delivery instruction should submit the update through UniUni's support chatbot, although changes submitted after the parcel is already out for delivery may not reach the driver in time.
UniUni package pickup and delivery confirmation
Customer pickup is not available everywhere. UniUni currently states that package pickup services are offered only in Canada and only in selected cities, including Montreal, Toronto and North York. In other Canadian locations and throughout the United States, customers may need to arrange re-delivery instead of collecting a parcel directly.
If Tracking says a shipment was delivered but you cannot find it, UniUni advises first confirming the Tracking status and reviewing the available proof-of-delivery photographs. You should also check with household members, neighbors, building management and mailroom or lobby staff who may have accepted or seen the package.
How to contact UniUni about shipment issues
UniUni provides different customer-service telephone numbers according to the customer's country and time zone. In Canada, customers in Pacific and Mountain time zones can call 1-604-229-2007, while customers in Central, Eastern and Atlantic time zones can call 1-647-360-4178.
In the United States, UniUni lists 1-424-284-2432 for customers in Pacific and Mountain time zones and 1-315-533-4690 for customers in Central and Eastern time zones. UniUni states that its customer-support call center is open Monday through Saturday from 10:00 am to 9:00 pm Eastern Time.
Customers can also use the UniUni chatbot on the official support page. If the chatbot cannot resolve the issue, it can connect the customer with a UniUni support agent. The support page also provides a help form for shipment-related enquiries.
For a damaged package, UniUni recommends taking clear photographs of both the damaged parcel and its contents and providing the photographs, contact information and tracking number through the support chatbot. UniUni customer support can then review the issue and determine the next steps. The recipient can also contact the merchant or seller for additional assistance.
If items are missing from inside a parcel or the merchant sent the wrong product, UniUni directs customers to the merchant, seller or vendor because UniUni is responsible for delivering the parcel rather than determining its retail contents. Returns are also handled according to the merchant's or seller's return process rather than directly through UniUni's last-mile delivery service.
