How can you get a Twitter Verified Account? Twitter Verified Accounts are labeled by a Twitter verified logo and is seen on twitter profiles of well known celebrities, artists, athletes, actors, public officials, and public agencies.
Twitter Verified Account
A verified profile basically mean that Twitter staff have contacted the the person or entity the account is representing and verified that it is indeed who they claim they are. This will really help avoid impersonation or identity confusion where celebrities are involved, and avoid potential lawsuits.
Note how some journalists got verified before John McCain!
There is a form where people can people can request verification (Now forms are closed to public). But Twitter warns that they verify a limited number of accounts and submitting a request does not guarantee account verification. They suggest you use this form only if your account is being impersonated, but it does not imply verification.
A good idea is to have a Twitter badge or logo on your official site linking back to your profile, which will help in easy verification. Twitter is still not reviewing verified business accounts, but they let you submit your request for verifying businesses for future consideration.
