Amazon Logistics is its own carrier
It is Amazon's in-house last-mile network, built to move a large share of Amazon's own orders alongside the national carriers it also uses for other orders.
Tracking prefixes
What shipping company uses TBA tracking numbers?
Amazon Logistics. A tracking number that starts with the letters TBA, usually followed by twelve digits, was never issued by USPS, UPS or FedEx — it belongs to Amazon's own delivery network, which is why it comes back not found on every carrier's own site.

Three letters, one network
TBA does not stand for a phrase Amazon publishes. It is simply the prefix that network's tracking numbers carry.
Why the carrier's own site says not found
USPS, UPS and FedEx each run their own numbering systems, and every tracking number entered on their sites is checked against records those companies generated. A TBA number was generated by Amazon Logistics instead, so none of the three national carriers has any record of it — the package is real and moving, but the lookup form is asking the wrong company.
The prefix marks the network, not the item
Seeing TBA on a tracking number says which network is carrying that specific package. It says nothing about what is inside the box or how the order was placed.
Sparse scans are normal
A TBA number often shows little movement until the delivery day itself, which reads as stuck to anyone used to the more frequent scan history a USPS or UPS number produces.
Where a TBA number actually tracks
The Amazon account that placed the order is the only place the full picture lives: sign in, open the order, and choose Track Package. That page carries the current status, the delivery window, and, on delivery day, a live driver map that no third-party lookup can reproduce, because the underlying data never left Amazon's own network.
If the package in question is something you are sending yourself rather than one arriving from Amazon, it never touches Amazon Logistics at all. A label bought through USPS, UPS or FedEx carries that carrier's own tracking number from the moment it prints, and it tracks on that carrier's site the normal way.
Where this comes from
- TrackingMore, Amazon Tracking — the TBA prefix identified as Amazon Logistics, twelve digits following the letters. Read 2026-08-19.
- Tracking-Status.com, TBA Shipping Carrier Tracking — TBA named as the carrier code for Amazon Logistics. Read 2026-08-19.
Neither of these is Amazon's own page; Amazon does not publish a single reference definition of the prefix. Both third-party tracking sites agree on the same identification, and the daily experience of anyone who has ordered on Amazon confirms it.
Common questions
What shipping company uses TBA tracking numbers?
Amazon Logistics, the in-house delivery network Amazon runs alongside USPS, UPS and FedEx for its own orders. A tracking number starting with the letters TBA was handed to that network, not to a national carrier.
What does shipping starting with TBA mean?
It means Amazon Logistics is carrying the package rather than USPS, UPS or FedEx. TBA is Amazon's own prefix, not an abbreviation any carrier publishes a definition for.
Why won't USPS, UPS or FedEx track a TBA number?
Because it was never issued by them. A TBA number is not registered in any national carrier's system, so pasting it into usps.com, ups.com or fedex.com returns not found even though the package is real and moving.
Where can a TBA number actually be tracked?
Inside the Amazon account that placed the order, on the order's Track Package page. That is the only place the live status, the delivery window and the driver map are exposed.
Does a TBA prefix mean the seller is doing something wrong?
No. Amazon Logistics is Amazon's standard fulfillment network for a large share of its own orders, and a TBA number is the normal, expected result of that routing rather than a sign of a mistake.
