Why is my tracking number not working on the carrier's website?

A tracking number that returns nothing on one carrier's site often means the order shipped with a different carrier than first indicated.

• Check your shipment confirmation for the actual carrier, since shippers sometimes switch to FedEx or another carrier to deliver faster.
• Try the number on the correct carrier's website.
• Both shipments can share one order reference while using different carriers.
• If it still fails, the shipper can confirm the carrier and number.

Timing is the other common cause. A brand new number can show as invalid or return "Unable to Track Shipment" until the carrier physically scans the package:

• Allow up to 24 hours after the order ships for the number to go live in the carrier's system.
• Tracking only activates after the first physical scan at a facility, so a freshly printed label shows no history at first.
• Status updates post in batches through the day rather than in real time, so check back in a few hours instead of refreshing constantly.
• Re-check the number for a missing digit, an extra space, or a stray character if you pasted it in.
• If it still shows nothing after a full business day, contact the shipper with your order number so the shipment details can be verified.
