what does in dispatch mean usps refers to a status update from the United States Postal Service (USPS) indicating that a package has been processed and is ready to be shipped from the USPS facility. “In dispatch” means that the package is in the final stages of preparation for departure, and it is typically waiting for the next step in the shipping process, such as being handed off to the delivery carrier or moving on to the next sorting facility. Customers can expect their package to be en route soon, and they will receive further updates as it progresses through the USPS system.
