The European Health Insurance Card is a free card issued by your national health insurance provider that gives you access to medically necessary, state-provided healthcare in any of the 27 EU countries, Iceland, Liechtenstein, Norway, Switzerland, or the United Kingdom.
It is located on one of the sides of modern CNS cards in Luxembourg.
To order a new EHIC or a replacement certificate in Luxembourg, you must provide your 13-digit national identification number (matricule number) for the CNS to process the request. You can visit the website of the Joint Centre of Social Security or request the certificate via MyGuichet.
