When the USPS tracking order or package is not being updated, it could be because the package has been registered for a tracking number but USPS has not received the package yet. Another case would be that USPS has received the package but has not scanned the package. Wait a few hours before tracking the package again.

Also, double-check the tracking number that you have entered. In some cases, a missing or mistyped letter or number could affect the results of the package you're tracking.
