Your affiliation number is an unique number that Liantis uses to find you quickly in our customer database. You will find this number at the top of your invoice under "our reference".

Can't find your invoice? Contact your personal customer advisor or one of our colleagues via support@liantis.be and give us your company number or national registration number. We will then provide you with the necessary information.

If you are affiliated to Liantis for your personal file as a self-employed person, your affiliation number is your national registration number. You will find your national number on the back of your identity card. Your national registration number consists of 11 digits and is formatted as follows: 00.00.00-000.00

You will find the contact details of your personal customer advisor on My Liantis under Contact, on the left-hand side of your screen.
