What is a verified account?
To prevent identity confusion, Twitter is experimenting (beta testing) with a ‘Verified Account’ feature. We’re working to establish authenticity with people who deal with impersonation or identity confusion on a regular basis. Accounts with a 
are the real thing!
What does it mean?
With this feature, you can easily see which accounts we know are ‘real’ and authentic. That means we’ve been in contact with the person or entity the account is representing and verified that it is approved. (This does not mean we have verified who, exactly, is writing the tweets.)
This also does not mean that accounts without the ‘Verified Account’ badge are fake. The vast majority of accounts on the system are not impersonators, and we don’t have the ability to check 100% of them. For now, we’ve only verified a handful of accounts to help with cases of mistaken identity or impersonation.
One thing you can do if we haven’t verified an account you’re wondering about is to check the official web site of the person and see if there’s a link back to their Twitter profile. (Again, lack of a link does not imply impersonation, either.)
