The yellow stickers contain all the necessary information to identify you. Stick a yellow sticker in the right place on each document to be sent to the health mutual: certificate of health care dispensed by a doctor, dentist, physiotherapist...

Each yellow sticker displays the following information : 

• the health mutual's name and number,
• the member's number, 
• the beneficiary's name, 
• the beneficiary's address, 
• the beneficiary's number, 
• the relevant refund code, 
• the sex code (1 = man, 2 = woman).  

Each member of the family registered with Mutualité Chrétienne has his/her own yellow stickers.  In mind Always stick the relevant yellow sticker on any document to be sent to your health mutual.

The SIS card is a welfare identity card. Everyone has one, so each dependent person in your household also has one. The SIS card contains visible and invisible data relating to the different Social Security sectors. 

The visible data are :

• the National identity number (numéro national),
• the surname and the first two forenames,
• the date of birth,
• the sex,
• the card number,
• the card validity start date,
• the chip.  

The chip contains all the invisible data. Only special equipment can read them. The data are your health mutual's number, your Mutualité chrétienne membership number, the start and end dates of your entitlement to health-care benefits and of your access to the "tiers payant" direct-payment facility.

The SIS card contains data other than those intended for the health mutual. You should always keep it on you. You need to produce it to the pharmacist, the hospital or polyclinic, health-care practitioners such as the doctor, dentist, physiotherapist, orthopaedist, home nurse, etc., your delegate, your employer, at the workplace, to the unemployment benefit office, the welfare-insurance office, to the CPAS health-insurance benefit office, etc.
The persons who are entitled to ask you for your SIS card can read only the data they need to be able to help you.
The SIS card cannot be used abroad. The data for health assistance abroad are on a different card, the "Carte européenne" (European Card) or "World assistance card".
