How do I change my name, address or email on my SIXT account?

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

1. Sign in on the website or in the SIXT App via "Log in | Register"

2. Open your account or profile area

3. 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.
