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.

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.
