Here are 10 things you need to know:

1. Be quick! Usernames on Facebook are being given out on a first-come, first-served basis.
2. It’s not possible to use a ‘generic word’ as your username. So don t try use terms like “newspapers “or car, that wouldn’t work
3. Be sure to choose the right username as once you pick a name, it’s yours for life.
4. Using your real name is not mandatory. The use of real names is advised by Facebook, but you aren’t limited in that regard.
5. If you made your Facebook account after 3pm on June 9th, you won’t be able to get a username yet.
6. The restrictions are even greater for Facebook Pages (public profiles). Facebook is only letting users who had accounts prior to 3pm on June 9 register for usernames this week. The social network says it’s a precaution to help prevent people from generating accounts just for ‘name squatting’ purposes. If you registered your Facebook account after that time, you’ll have to wait till June 28 at 12:01am to get your new name.
7. 5 characters is the minimum number of of characters you can use. Only letters, numbers, also a full stop could be contained in a username. Don’t waste your time using special characters e.g $#@%
8. Your current privacy settings will be applied to your new URL. Depending on your privacy settings, though, people may not be able to see much there. Whatever settings you currently have on your account will apply, so if your profile is set to be private, it’ll remain private – even on the new address.
9. Trademarks will be protected. Facebook says it’ll work to protect intellectual property & trademark rights. You will be able report rights violations.
10. Your Facebook username might be used for more things in the future. Even if no information has been revealed yet about that, whatever name you pick is likely appear in more place in the future
