Costco doesn't operate its own parcel network for most online orders. When you order a small or medium item on Costco.com, it's handed to one of the national carriers — UPS, FedEx, or USPS — and Costco assigns the carrier automatically based on the item, its weight, and your address. There's usually no way to choose which one, so two items from the same order can arrive on different days with different couriers, each with its own tracking number.
Large and bulky items are handled differently. Furniture, mattresses, major appliances, TVs, and exercise equipment are typically delivered through Costco Logistics, Costco's own heavy-goods delivery arm. These orders are followed as a scheduled delivery — you're contacted to arrange a delivery date and window, and the status reflects that appointment rather than a stream of parcel scans. Depending on the service, Costco Logistics may bring the item to your room of choice or leave it at the threshold. Because the experience is appointment-based, a large-item order often shows scheduling status instead of a UPS/FedEx/USPS-style scan history.
Same-Day grocery orders are fulfilled through Instacart under the Costco Same-Day banner: a shopper picks your items at a local warehouse and drives them to you inside the window you chose, followed as live order status in the app rather than a carrier tracking number. Costco.com serves the United States; Costco's Canadian (costco.ca) and UK (costco.co.uk) stores are separate sites with their own local carriers. Items from Costco Next, Costco's curated third-party marketplace, ship directly from the brand using that brand's own carrier, so the tracking number belongs to whichever courier the seller uses. This page lists the carriers behind Costco orders in 2025–2026 and how to recognize each tracking number. If you'd rather not guess which carrier's site to open, 24hTrack auto-detects the carrier from the number and follows the parcel in a single timeline.
One of the national carriers Costco uses for parcel-shipped orders. When UPS is assigned, the item travels on the UPS network and every scan from pickup to delivery shows on UPS tracking. Costco assigns the carrier automatically — you generally can't request UPS specifically. Tracking numbers: 18 characters — 1Z followed by 16 letters and digits
A national carrier Costco assigns to many parcel-shipped orders. FedEx moves the item from the fulfillment center to your door with scans available on FedEx tracking. Economy services may hand the final mile to USPS in some areas. Tracking numbers: Usually a 12-digit number; FedEx Ground shipments use 15 digits
The postal carrier Costco uses for a share of parcel-shipped orders, especially lighter items. The parcel moves through the postal network with delivery scans on USPS tracking. Tracking numbers: A 22-digit number that usually begins with 9 (USPS IMpb tracking)
Costco's own heavy-goods delivery service for furniture, mattresses, major appliances, TVs, and exercise equipment. Rather than a stream of parcel scans, a Costco Logistics order is arranged as a scheduled delivery — you're contacted to set a date and window, and the status reflects that appointment. Depending on the service level it may be room-of-choice or threshold delivery, so there's usually no standard parcel tracking number to paste into a carrier's site.
Costco's same-day grocery service, fulfilled through Instacart. A shopper picks your items at a local warehouse and delivers them within the window you choose. It's followed as live order status and notifications in the app — the shopper starting your order, an updated window, and delivery — rather than a carrier tracking number, so there's no separate number to look up.
For parcel-shipped items, Costco uses UPS, FedEx, or USPS and assigns the carrier automatically based on the item, its weight, and your address. Large and bulky items — furniture, mattresses, appliances, TVs — are usually delivered by Costco Logistics as a scheduled delivery, and Same-Day grocery orders are delivered through Instacart. Whichever carrier is on a parcel order is the one that brings it to your door.
There's no separate 'Costco' number — the tracking number belongs to whichever carrier was assigned. A USPS shipment is a 22-digit number that usually starts with 9; a UPS shipment is 18 characters beginning with 1Z; a FedEx shipment is typically 12 digits (some services use 15). Paste whichever one you have and 24hTrack will detect the carrier for you. Large-item Costco Logistics deliveries and Same-Day orders are followed by scheduling or order status instead of a carrier number.
Big and bulky items usually go through Costco Logistics, Costco's own heavy-goods delivery service. Instead of ordinary parcel scans, you're contacted to schedule a delivery date and window, and the status reflects that appointment. Depending on the service it may be delivered to your room of choice or left at the threshold, so these orders typically show scheduling status rather than a UPS/FedEx/USPS scan history.
Costco Same-Day is fulfilled through Instacart and followed inside the app as live order status, not with a carrier tracking number. You'll get notifications when the shopper starts and can watch progress in real time, plus a message if the delivery window changes. Because there's no UPS/FedEx/USPS number, a same-day order can't be looked up on a carrier's tracking site — only parcel-shipped orders have a carrier number.
Costco.com serves customers in the United States. Costco operates separate country websites — for example costco.ca in Canada and costco.co.uk in the United Kingdom — each with its own local delivery carriers, so an order placed on one country's site is delivered by that country's couriers rather than shipped across borders.
Parcel tracking often stays quiet in the gap between a label being created and the carrier's first movement scan — an order can show 'label created' with no updates for a day or so, especially over weekends. If a parcel order stalls well past its estimated delivery date, the carrier on the label — UPS, FedEx, or USPS — can confirm where it is. For a large-item Costco Logistics delivery, check the scheduled delivery status; for a Same-Day order, check the Instacart order status and notifications instead.
