You may be wondering, does anyone actually use UUIDs?

The Answer: YES!

Here are some examples:

The UPS billing center uses UUIDs as the .zip file name for their invoice downloads.

hulu.com

Hulu uses UUIDs in urls for every show and movie on the site. They even use two UUIDs in Watch Party invite links!
