You can update your address and phone number yourself once you sign in via "Sign in | Register" on the website or in the SIXT App. Two things need us: your account email address (your login) and a name change — just send us a quick message and we'll take care of it.
What you can change yourself
In your account:
Add or change your home address
Add or change your phone number
Delete your account
In your booking profiles:
Add or change your billing address
Change the booking profile's email address
Add or change your payment method
Create a new profile
Deactivate a profile
How to make changes
Sign in on the website or in the SIXT App via "Log in | Register"
Open your account or profile area
Update the relevant field and save
Your account email address (login)
The email address you sign in with can't be changed yourself. Just send us an email using the contact options below, and we'll update your login address for you.
Good to know: the email address in a booking profile is separate, and you can change it yourself at any time (see above).
Name change
You can't change your name yourself (for example after marriage or divorce). Message us on live chat with your rental agreement number and proof of the name change (for example a marriage certificate, court order for a name change, or updated driver's license), and we'll update your name for you.
