package in transit usps is a status update indicating your shipment has left the origin facility and is currently en route to its destination. This stage can last several days depending on distance, service level, and carrier load. While “in transit” means the package is moving, it doesn’t always include regular scans. Customers tracking a USPS package in transit should allow for a buffer before assuming delays. It’s a common part of the shipping lifecycle and typically precedes “out for delivery” or “delivered” statuses in USPS tracking.
