My USERNAME appears as numbers

[ClaraToma]

I am able to link my account to facebook (and I login with facebook), but when I make collaborative playlists with friends and stuff, my username comes up as numbers? 

Would really like to change this...any suggestions? 

Thanks!

Hmm. That's weird. Does this only happen when collaborating? 
Kindly try logging in to your spotify account, then go to account overview. Check if you have an existing username. Let me know your progress. Goodluck 😄

Hi!

It's currently not possible to change your Spotify username.
When your Spotify user is linked to Facebook, your username will be a 10-digit number, but generally people should see your Facebook name on your profile and else.
If you have more questions, feel free to ask. 🙂
