A UPS tracking number is usually 18 characters long. It starts with “1Z,” followed by the shipper's ID, a service code, and a unique package number. Here’s how it breaks down:

• 1Z: Prefix for UPS shipments
• Shipper number: 6 alphanumeric characters
• Service indicator: 2 digits showing the delivery type
• Package ID: 8 digits that identify the parcel

Example: 1Z12345E6205277936

Before contacting UPS, check the tracking page for the latest shipment progress. Have your tracking number, delivery address, sender name, and InfoNotice number ready if you have one.

UPS tracking numbers can also appear in other formats depending on the shipment type. Standard package numbers may start with "1Z", start with "T", or appear as 9-digit or 12-digit numbers. Freight, air cargo, ocean freight, UPS Delivery Notice, UPS Service Notice, and UPS Mail Innovations shipments can use different references.

Where can I find my UPS tracking number?

You can usually find the tracking number in the order confirmation email, shipping confirmation email, UPS receipt, package label, return label, UPS notification, or UPS My Choice dashboard. If you cannot find it, ask the sender or online store to confirm the shipment details.
