tracking status not available usps can occur when a package’s tracking number is not recognized in the USPS system or when the package has not yet been scanned into the system. This situation may happen if there’s a delay in processing the shipment or if the tracking information hasn’t been updated yet. Customers should wait for a day or two for the tracking status to update. If the issue persists, contacting USPS customer service for assistance may help resolve the problem.
