Go.USA.gov lets U.S. government employees create short .gov URLs out of any .gov, .mil, or .si.edu URLs. If you are a U.S. government employee and would like to use it, you can register for a free account here. To register, you must have a verifiable U.S. federal, state, or local government e-mail address.
The URL shortener gives people who work for the U.S. government the ability to create short, trustworthy .gov URLs for use on Twitter and other services with character restrictions. Go.USA.gov also tracks the number of clicks each shortened URL receives, so you can measure the impact of your outreach.
Go.USA.gov is open source, and was developed in Drupal using the Drupal Core, Shorten, Short URL, and TLD restriction modules.
