Google and most search engines let you search for a package with ease but should Google show those packages in your Google now based on past search history or based on your Google Wallet orders or Gmail confirmation emails? Google now let's you opt out if you do not want to show packages in Google Now.

I assume they added this opt out because of those folks who are CCed on all the orders placed for companies or for e-commerce site owners who get lots of these tracking numbers? Imagine having hundreds of tracking numbers show up in your Google Now notifications.
You can now opt out via the Google Dashboard.
