Hello, So my husband sent me a package on december 7th by UPS. I looked today on the UPS site with the tracking number if my package moved or any updates. This is what I got : The tracking number has 18 characters and does begin with 1Z. I am so confused. Any help please ?
What does a UPS tracking number look like?
When you ship a package with UPS, you’ll receive a tracking number that helps you follow its progress. This number is provided by UPS or the sender and is required to check the delivery status.
Common UPS tracking number formats:
- 1Z999AA10193716784 — The most common format, starting with "1Z" followed by 16 characters.
- T9999999999 — Used for specific package types.
- 999999999999 — A 12-digit number often used for domestic shipments.
- 999999999 — A shorter 9-digit format used in select cases.
Other specialized formats include:
- PRO numbers for freight shipments
- House Air Waybill for air cargo
- House Bill of Lading for ocean freight
- Delivery Order/Sub-PRO numbers for LTL and TL child shipments
You may also encounter reference numbers like the UPS Delivery Notice (12-digit barcode on a missed delivery slip) or a Service Notice, both used to track or reschedule delivery.
Where to find your UPS tracking number
You can locate your tracking number in these places:
- Shipping receipt from a UPS location or drop-off point
- Confirmation email after ordering or shipping online
- Shipping label on the outside of the package
- UPS My Choice dashboard, if you’re signed up
- Text or email alert from UPS or the sender
If you can’t find it, contact the sender or try tracking by reference number on the UPS website.
How do I track my UPS packages?
You can track a UPS shipment by entering the tracking number on the UPS website, mobile app, or Ship24. These tools show real-time updates, scan history, and estimated delivery times.
Track on the UPS Website
- Visit the UPS Tracking Page.
- Enter your tracking number(s) in the search box.
- Click "Track" to view your shipment’s status and delivery details.
Track with Ship24
If you prefer another way of tracking your UPS parcels, you can use Ship24. To track with Ship24:
- Go to the Ship24 homepage or use the tracking field above.
- Type your UPS tracking number into the box.
- Click the search icon to see the latest updates.
Ship24 works across hundreds of couriers, so even if your package switches carriers during transit, you can still follow its progress from one place.
Track using the UPS mobile app
Here's how to track using the mobile app.
- Download the UPS app on iOS or Android.
- Log in to your UPS account.
- Tap "Track," then enter your tracking number or scan the barcode on your parcel.
When does UPS deliver packages?
UPS delivers Monday through Friday for most services, with Saturday delivery available in many areas. Sunday delivery is also offered in some locations for residential packages.
Typical delivery windows are:
- Residential addresses: Between 9:00 a.m. and 7:00 p.m. (sometimes later)
- Business addresses: By the close of business
Weekend availability depends on your location and the shipping service selected. You can check eligibility during checkout or by tracking your shipment.
I ordered some items from two totally different suppliers, and I noticed that the entire tracking number was exactly the same, except for the last 3 digits.
Does that mean they were shipped using the same account number, and potentially shipped from the same organization?
I found this information in another post. Is it still relevant? https://www.reddit.com/r/AmazonSeller/comments/rw6ea3/i_need_my_ups_account_number_associated_with_a/
The account number is the 6 numbers/letters after 1Z.
