I would like to grant a third-party access to my customer number. How do I arrange this?

You can give a third party access to your BASE account for purposes such as requesting data. Making changes is not possible for a third party. So you remain the only manager of your account. 

How do you do this?

Granting acces to a third-party is only possible through our customer service. Call us on 1999 (with a BASE number) or on +32 486 19 1999 (with another number).
