Unfortunately it's not currently possible to change your Depop username.
If you really want to change your username what we can close your current account and allow you to create a new one with your desired username. Get in touch with us at support@depop.com and we can help you do this.
We’re unable to provide a timeline for when this will change, but rest assured you will be the first to know. It won’t be long before you’ll be able to update your name to fit your new look.
