As my mom's unofficial tech support hotline, I got a call from her today with a problem: She had a tracking number for a package, but didn't know who the shipper was.

Me: "Just plug it into Google."
Mom: "But Tom, I don't know what company shipped it."
Me: "Just plug in the number itself, Mom. It's cool. See what happens."

Google didn't let me down. She got a link to the USPS website with her tracking info - the one she hadn't checked. Next time you have a mystery package en route, try it yourself.

Mom: "We need to tell people about this." Yes, Mom. Google Search By Number.
