Track and get real-time status updates for UniUni shipments.
UniUni is a last-mile delivery carrier operated by Uni Express Inc., a Canadian logistics company founded in 2019 in Vancouver, British Columbia. Rather than running long-haul transport, UniUni handles the final stage of a parcel's journey — from one of its 100+ warehouses and sorting centres in North America to the recipient's door — using a network of more than 100,000 registered gig drivers. The company says its delivery coverage reaches about 80% of Canada's population and 65% of the US.
UniUni built its volume as the primary last-mile partner for Shein in North America and now also delivers for Temu, AliExpress, YesStyle, and other marketplace sellers, processing more than one million parcels per day. It has raised more than US$200 million in venture funding, including a US$50 million Series C led by DCM in April 2024, and in May 2026 announced a merger to go public at a valuation of about US$1 billion. If your tracking number starts with UUS, the final delivery is being handled by UniUni.
Ships for: Shein, Temu, AliExpress, YesStyle, TikTok Shop sellers, Direct-to-consumer merchants via Shopify, WooCommerce, and ShipStation integrations
Tracking number format: UUS prefix followed by about 16 digits (roughly 19 characters total); some variants mix letters and digits after the prefix (e.g. UUS6181780830420033)
Typical delivery time: UniUni's last-mile leg typically takes next-day to seven days across the US and Canada, per the company's own published figures. Total delivery time for a Shein, Temu, or AliExpress order is longer, because the parcel completes an international leg before UniUni's first scan.

The most common cause is the handover gap: the retailer creates a label and tracking number days before the parcel physically reaches a UniUni sorting facility, so the number shows no movement at first. Cross-border Shein and Temu parcels also travel an international leg before UniUni's first scan. If nothing appears after several business days, confirm the number with the retailer, or run it through a multi-carrier tracker like 24hTrack to see updates from every leg of the journey in one place.
Yes. UniUni is a real Canadian logistics company, founded in 2019 in Vancouver, that delivers last-mile parcels for Shein, Temu, AliExpress, and other marketplaces using a network of more than 100,000 gig drivers. It has raised more than US$200 million from investors including DCM and Bessemer Venture Partners, and in 2026 announced a deal to go public at a valuation of about US$1 billion. Some shoppers report problems with proof-of-delivery photos or stalled tracking, but the carrier itself is legitimate.
UniUni only handles the final leg, from a local sorting centre to your door. The company quotes next-day to seven days across the US and Canada for that stage, and most parcels arrive within a few days of the first UniUni scan. Total delivery time for a Shein or Temu order is longer because the parcel crosses an international leg first — TechCrunch reported UniUni helped cut Shein's delivery times from 10–14 days to around 4–5 days.
First check the proof-of-delivery photo in the tracking details — some shoppers report photos showing the wrong door or building, which usually means the parcel went to a nearby address. Look around your property, mail room, or with neighbours, and wait 24 hours, since parcels are occasionally scanned as delivered slightly early. If it still hasn't appeared, file a claim with UniUni support and contact the retailer — Shein and Temu generally refund or reship items confirmed as not received.
Most UniUni tracking numbers start with the prefix UUS and run about 19 characters in total, for example UUS6181780830420033. After the prefix, the number is usually all digits, though some variants mix letters and numbers. If your marketplace order shows a number in this format, the final delivery is being handled by UniUni, even when earlier legs of the journey were carried by a different company.
UniUni is best known as a last-mile partner for Shein and Temu in the US and Canada — Shein was its anchor client as the company scaled. Orders from AliExpress, YesStyle, and some TikTok Shop and other marketplace sellers are also delivered by UniUni in covered areas. It additionally serves direct-to-consumer merchants through integrations with Shopify, WooCommerce, ShipStation, and similar platforms, so a UUS tracking number can appear on orders from smaller stores too.
UniUni uses independent gig drivers, so a parcel marked out for delivery has been assigned to a driver's route — but routes are sometimes cut short or reassigned, and the parcel returns to the warehouse overnight without a new scan. Deliveries are usually re-attempted within a day or two. If the status sits unchanged for several days, contact UniUni customer support with your UUS number, or ask the retailer to open an inquiry on your behalf.
