I want to delete my account but I forgot the last 6 digits on email address so I cannot log in.

Maybe because of GDPR, airbnb staff did not want to help me. Any advice on this?

Assuming you log in on Airbnb with emailaddress + password.

The emailladdress is nowhere to be found on your computer / phone ?

Airbnb can not delete the account without verifying you being the owner of the account.

Your profile shows no active listing(s)  nor any reviews, no personal information and no personal photo.

So the account seems not be used very active. Maybe just leave it there if Airbnb is unwilling to delete it ?
