Here is a one click tool for social media geeks. If they wish to check availability of their username on various social media sites, they can do in through Check Usernames. Simply type in the username you wish you use and click on ‘Check User Name’ button. It will automatically process and check availability of your typed username.
For the sites where your username would be available it will indicate that it is ‘Available’ and for the ones where it has already been taken by someone else, it will fade out with a lighter colour. There are around 160 popular social media sites to check your username availability from. If you get a premium service, you can check your brand name availability and username availability for up to 300 websites.
The site is a good tool to use especially for those who are looking to open up an account or join as a member any of the given social media sites. They can simply search their desired usernames and go ahead smoothly with their social media marketing and social media promotion. There are more sites here than you would have probably heard of. So there is a high chance that the site you are looking to join is on the list. Better check your username availability before that site asks you for it.
