With MyAcea Acqua, you can change the following in real time:

your personal contact details (e-mail address, landline, mobile telephone, certified e-mail address and fax number and details of your registered form of ID);

In the event of a change to the VAT number or tax code of a private or legal subject, a name change is required.
