Drag this thing to your bookmarks bar:
Tracking


Here's how it works:

Select some text with tracking numbers in it, then click the bookmarklet
Be sloppy. Select as much text as you like - we'll sort it all out
Spaces or hyphens? We're cool with that
Oh, and if it's UPS or DHL, but USPS delivers it, then we'll just open up both sites


And here's a bunch of fake numbers if you want to test it out
