In order to allow the CNS to process the request, it is essential to indicate the 13-digit national identification number (matricule number).
Social security card in Luxembourg - General information
The Luxembourg social security card normally has two sides: a national side and a European side.
National side - Luxembourg social security identification card
This side represents the "Grand Duchy of Luxembourg social security identification card" and contains the 13-digit national identification number and the name of the cardholder (principal insured or co-insured).
Among other things, it entitles you to health, maternity and long-term care benefits in Luxembourg.
It is valid for as long as the cardholder is insured in Luxembourg.
European side - European Health Insurance Card
The European side is known as the European Health Insurance Card and is identical in all Member States.
It entitles you to coverage for urgent and immediately necessary healthcare during a temporary stay in the countries of the European Union (EU), the European Economic Area (EEA) and Switzerland.
Order the European Health Insurance Card and provisional replacement certificate
You can use the European health insurance card or its equivalent document, the provisional replacement certificate, if you need medical care during a temporary stay in a Member State other than the one in which you are insured.
You can present these documents directly to the service provider; you do not need to contact the local health insurance fund beforehand.
The card is valid for a limited period, indicated by an expiry date on the card.
First card or card that has already expired
If your current card has expired or if you do not have a card, you can order it on the website of the Joint Centre of Social Security (Centre commun de la sécurité sociale).
Card still valid but due to expire soon
If your current card is still valid but is due to expire soon, you can order a new card by e-mail using the contact form.
Card delivery time
It takes a maximum of 3 weeks from the time of your request to delivery of the card to your official address.
Please take this time into account when ordering your card.
It is important that you also notify the CNS of any change of address so that your card and any other mail can be delivered correctly.
Provisional certificate of replacement
In case of emergency, you can can request a provisional replacement certificate (valid for three months as of the issue date) via MyGuichet.
In the event of a request WITH authentication and if you have activated the eDelivery function, the provisional replacement certificate for the European health insurance card is sent directly to your private secured eSpace on MyGuichet.
In the event of a request WITHOUT authentication on MyGuichet and/or if the eDelivery function is not activated, the provisional replacement certificate will be sent by mail. In order for it to be sent correctly, your address must be up to date.
Period of validity of the European Health Insurance Card
The European Health Insurance Card is valid for a limited period. The period of validity is automatically calculated on the basis of the previous duration of affiliation.
So, for example, in the first year of a new insured person's membership, European cards are only valid for 3 months.
The period of validity of the cards is extended as the duration of membership increases.
However, if membership of Luxembourg social security ceases before the expiry date of the card, the card loses its validity immediately on termination of membership.
