Yes, but only through a paid service called Multi-Channel Fulfillment, and only for orders that never touch another carrier's label. Amazon's own delivery network can pick, pack and ship orders placed on a seller's own website or another sales channel under that program. It does not pick up a box that already carries a FedEx, UPS or USPS label and finish the delivery itself — a tracking number issued by FedEx stays inside FedEx's own network from pickup to the door.
Whether Amazon fills someone else's order is a different question from whether Amazon carries someone else's already-labeled box.
"Does Amazon deliver for other companies" gets asked about three different situations, and only one of them is a yes. Sorting out which one applies is most of the answer.
Amazon's fulfillment centers can pick, pack and ship orders that were placed away from Amazon.com — a brand's own storefront, another marketplace — using the same inventory and delivery network a seller already pays Amazon to hold for its own listings.
Once a carrier issues a tracking number, that carrier's own network moves the box to the door. Amazon's delivery drivers carry Amazon-issued labels; they do not pick up parcels another carrier already accepted.
A person cannot hand Amazon a random box the way they would drop one at a FedEx counter. Access runs through Multi-Channel Fulfillment, which requires a seller account and inventory already stored with Amazon.
Amazon's own fulfillment page describes it plainly: "Pick, pack, and ship support for non-Amazon sales channels." That is the service, sitting inside what Amazon now calls Supply Chain by Amazon alongside freight, warehousing and its Amazon.com fulfillment business.
The channels it names are a brand's own direct-to-consumer website, wholesale orders and social-commerce storefronts such as TikTok Shop, with Shopify called out as a supported platform. A seller enrolls the same inventory already sitting in an Amazon fulfillment center, and Amazon fills orders from it no matter where the order was placed. Amazon's published delivery tiers for this service are standard, arriving in 3 business days, and expedited, arriving in 2.
That is different from a package a customer sees marked FedEx, UPS or USPS on an Amazon order's own tracking page. When that happens, the leg of the trip in question was handed to that carrier's network, and from that point its tracking number belongs to that carrier the same way a TBA number belongs to Amazon — a lookup on the wrong carrier's site returns not found, but the box is still moving.
Yes, through Multi-Channel Fulfillment, a paid part of Supply Chain by Amazon. It picks, packs and ships orders placed on a seller's own website or another sales channel out of Amazon's fulfillment centers, using the same delivery network Amazon uses for Amazon.com orders.
No. A package that already carries a FedEx label and tracking number stays inside FedEx's own network from pickup to the door. Amazon's delivery network only carries packages that were shipped through Amazon in the first place, either an Amazon.com order or an order placed through Multi-Channel Fulfillment.
Not the way FedEx or UPS is. Multi-Channel Fulfillment only covers orders for sellers who already store inventory in Amazon's fulfillment centers, so it is a fulfillment program tied to that inventory, not a walk-up shipping counter for an arbitrary box.
The service inside Supply Chain by Amazon that fills orders placed away from Amazon.com, a brand's own website, a marketplace such as Shopify or TikTok Shop, from the same inventory a seller keeps for Fulfillment by Amazon, on Amazon's published standard and expedited delivery tiers.
Because that leg of the delivery was handed to that carrier's own network, and its tracking number belongs to that network from that point on, the same way an Amazon Logistics TBA number only tracks inside Amazon's own systems.
