# 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.

A tracking number that fails may belong to another carrier, such as FedEx, or may need up to 24 hours after shipping for the first scan to register.
