Changing my username
Your username is your unique identifier on Freelancer.com. Traditionally, username is permanent and cannot be changed. However, for a limited time, you can take advantage of our Username Change Service, allowing you the opportunity to refresh your username to better reflect your online persona.
Without the Username Change Service, you will have to close your account, and create a new one with your desired username. Should you go with this option, make sure to use a different email address as this information should be unique in every account.
Username vs. Display Name
Note that your display/public name, is different from your username. Your display name is your first name and last initial (for personal accounts) or your elected company name (for corporate accounts).
In this sample of a personal account, (1) Chuck B. is the display name and (2) heychuck is the username.
