Why did I receive tracking, but it says the label has only been generated and there has not been any movement?

The labels are sometimes generated ahead of time to make the shipping process flow faster. When tracking is uploaded, it is in mass. We also have the packages picked up by the truckload, so the packages are not scanned individually when it is picked up by USPS or FedEx. An individual package is not scanned until it reaches its hub and is unloaded.
