Amazon Logistics Explained: How TBA Tracking Numbers Work

A TBA tracking number means Amazon is delivering your package themselves — not UPS, FedEx, or USPS. Amazon Logistics now handles 75% of Amazon's own deliveries, and their tracking is excellent once you know how to read it.

See a tracking number starting with 'TBA'? That's Tracked By Amazon — Amazon Logistics (AMZL) is handling the delivery, not a third-party carrier. Amazon now handles roughly 75% of its own packages this way, and their delivery network has become fast and reliable.

Quick Tip

You can track any TBA package on ParcelsZen. Just enter the full TBA number for real-time Amazon delivery updates.

What Is Amazon Logistics?

Amazon Logistics (AMZL) is Amazon's own delivery service, built since 2014. Today it handles roughly 75% of Amazon Prime deliveries in the US. Amazon does this using a combination of their own delivery vans (the blue Amazon-branded vehicles), Amazon Flex drivers (independent contractors who deliver using their personal vehicles and the Amazon Flex app), and in some markets, Amazon's own aircraft. Amazon's Delivery Service Partners (DSPs) are small businesses contracted to manage fleets of Amazon vans.

Amazon Logistics is now one of the top-5 largest parcel carriers in the United States.

What Does TBA Mean in a Tracking Number?

TBA stands for "Tracking By Amazon." Example: TBA123456789000

TBA confirms Amazon Logistics is delivering — not UPS, FedEx, or USPS. TBA numbers cannot be tracked on UPS.com or FedEx.com. Use Amazon's website, the Amazon app, or ParcelsZen.

TBA Tracking Status Meanings

'Package received by carrier'

Amazon has the package and it's sorted for your delivery route.

'Out for delivery'

An Amazon driver or Flex contractor has the package on their route today.

'Arriving today by [time]'

Amazon's algorithm estimates delivery before a specific time. Generally reliable but an estimate, not a guarantee.

'Delivered – Left at front door'

Package left at your door. Amazon often takes a delivery photo — check your order page.

'Delivered – Handed to resident'

A person at your address received the package from the driver.

'Attempted delivery – No secure location available'

Driver couldn't find a safe spot to leave the package. Reattempt expected next day.

What to Do When an Amazon TBA Delivery Is Missing

  1. Check all spots: front door, back door, mailroom, package locker, with a neighbour. Look for a delivery photo in your Amazon order.
  2. Wait 24 hours: Amazon sometimes marks packages delivered slightly before arrival. Usually self-corrects.
  3. Contact Amazon: through your order page. Amazon typically reshipssor refunds for missing packages promptly.
  4. Check Nextdoor or Ring: to see if a neighbour accidentally received your package.
Amazon's Delivery Guarantee

For Prime orders, Amazon will typically offer an immediate reship or full refund for packages reported missing through your order page.
