If you’re as obsessed as I am about tracking some packages, you’ll get sick of typing in your tracking number and submitting the form over and over. But if you go to:
http://trkcnfrm1.smi.usps.com/PTSInternetWeb/InterLabelInquiry.do
it doesn’t work because the form used a POST method.
Well, on the previous page, the form input field was called strOrigTrackNum. Some sites let you post a form via the GET method, so let’s see if this works:
http://trkcnfrm1.smi.usps.com/PTSInternetWeb/InterLabelInquiry.do?strOrigTrackNum=[your tracking number]
Yup! Worked fine. Now you have a URL that you can bookmark to quickly track your shipment.
