Googling 'USPS tracking number' or 'UPS tracking number' places a widget on the search results page that allows you to directly enter a UPS or USPS tracking number. You think this is in good faith, when you could just spend 0.2 seconds to click the link right below the widget to go right to the official website to do it more directly? I bet Google scrapes the tracking number & uploads the tracking data directly to the Megacluster to further train the Grid so it Can Serve You Better (TM)
