People frequently come to Google Search looking to find information on the status of their packages. To make it easier to find, we have created a new package tracking feature that enables shipping companies to show people the status of their packages right on Search. Here’s an example of how this information may appear: 
Through the package tracking Early Adopters Program, which is available in all countries, shipping companies can sign-up to participate in this feature and give feedback on how to improve it. To take part in the program, a carrier will need to provide a RESTful JSON or XML API that returns the package tracking information. We can work with you to reuse an existing API or setup a new one.
