Back before Google Now started automagically extracting tracking numbers from email and displaying updates as cards, I used an app called Package Buddy to do it. You pasted in the tracking number and it provided notifications when the package's status changed. I mention it because in some cases it could automatically recognize the carrier from the tracking number. You might give that a try.

If you buy/ship a lot of stuff then Package Buddy for Android and Blackberry is a great app. Everything is on one page, each package has a tab to it's tracking page through the courier for more details. Can set notifications for every update or when the item is out for delivery/delivered.
If you used Android. Package Buddy is fantastic app as it lets you select originating and delivering carriers. I use it for tracking USPS and it is quite effective.
Pakcage Buddy supports a ton of shipping companies. The interface is kind of clunky, but it mostly works.
Edit: Deliveries looks nicer.
Se você faz compras internacionais ou usa transportadoras além dos correios, o package buddy é bem melhor.
I've been using Package Buddy for quite some time now. Have no complaints.
Personally I prefer Package Buddy.
