Typically it was reserved for media stars and politicians, but no longer.
As of July Twitter has opened up an application process to get a "verified" account. Before you begin, review your account and ensure you are happy with all the information, including contact methods, picture etc. If you change any of these after being verified it can cause you to lose your "verified" status and you'll be starting all over again.
So how can you try to get a verified account? Here's what you need to do.
1) Log in to your Twitter account and fill out a Request To Verify Account
3) Provide an explanation on why you should be verified. It doesn't need to be "War & Peace" but a few lines explaining your impact on social media are required to provide context.
4) Click the "Next" and "Submit" buttons.
5) Wait. Twitter will review your request and let you know their decision. If they say "No" you can try again in 30 days.
While they have opened up the application process, it's still difficult for the average person to get a "verified" badge, so don't be too disappointed if your request is declined.
