Do I have to carry my ID card at all times in Luxembourg?
It depends what you mean by "must". In Luxembourg, the law of 19 June 2013 on the identification of natural persons makes an ID card compulsory from age 15 for every Luxembourg national living in the country: you must hold a valid one. But holding is not carrying: no law obliges you to have it on you at all times, and going out without it is not an offence in itself. During a check, the law of 18 July 2018 on the Grand-Ducal Police only requires you to establish your identity by any means — driving licence, another document, a witness. If you cannot, the police may hold you long enough to verify who you are, not hand you an automatic fine. Third-country nationals, however, must be able to show their residence permit. The myth: "they can fine me on the spot because I don't have my card on me" — false; what counts is being able to establish your identity, not producing that exact piece of plastic.
📋 The rules
- Compulsory to hold from 15: the law of 19 June 2013 requires every resident Luxembourg national to hold a valid ID card from age 15; below that it is optional and issued at the parents' request.
- Carrying is not required: no provision obliges you to keep your card on you at all times, and simply forgetting it is not, by itself, a fineable offence.
- Identity checks: during a check, the law of 18 July 2018 asks you to establish your identity by any means, the card being just one option among others (licence, passport, official document).
- Holding for verification: if you cannot establish your identity, the police may hold you for as long as needed to verify it, informing you of your rights; fingerprints and photos are used only where necessary.
- Foreigners and residence: third-country nationals must be able to present their residence permit or equivalent, a duty distinct from the Luxembourg ID card.
🔓 Exceptions
- Under 15: the card is not compulsory for children; it is issued at the request of a parent with parental authority, notably for travel.
- Luxembourgers abroad: for a Luxembourg national living outside the country, holding the national ID card is optional.
- Driving and other contexts: at the wheel you must show your driving licence and the vehicle papers; these are duties under the Highway Code, not an obligation to carry the ID card.
⚠️ Penalties & fines
Not having your card on you is not punished as such: there is no fine "for forgetting your ID card". The real risk is practical. If you are checked and cannot establish your identity, the police may hold you until it is confirmed — a detention that can last several hours and take place at the station, with fingerprints and a photograph if that is indispensable. Knowingly giving a false identity to an officer is, by contrast, a separate criminal offence. Moreover, not holding a valid card when it is compulsory puts you in breach of the 2013 law and complicates every formality, a trip or a vote. For third-country nationals, being unable to show a residence permit has far heavier consequences, up to measures affecting the right to stay. Finally, an expired card is no longer a valid identity document for travel.

❓ Frequently asked
Can the police fine me if I don't have my card on me?
No, there is no automatic fine for not carrying your ID card, because no law requires you to have it on you at all times. What the police expect is that you can establish your identity by one means or another; failing that, they may hold you long enough to verify it.
Am I required to hold an ID card in Luxembourg?
Yes, if you are a Luxembourg national, live in the country and are at least 15, the law of 19 June 2013 requires you to hold a valid ID card. Below the age of 15 the card stays optional and is only issued at a parent's request, for example for a trip.
What documents can I show instead of my card?
During a check, the law lets you prove your identity by any means: a passport, a driving licence, or any other official document bearing a photo. The ID card has no exclusive status; what matters is that the officer can be sure of who you are.
What happens if I refuse to give my identity?
If you cannot or will not establish your identity, the Grand-Ducal Police may hold you for the strictly necessary time to verify it, under the law of 18 July 2018. Giving a false identity to an officer, by contrast, is a full criminal offence, far more serious than simply forgetting your card.
Must cross-border workers and tourists carry an ID document?
EU citizens travel with their national card or passport and need not carry any Luxembourg document. Third-country nationals, however, must be able to present their residence permit, a duty specific to immigration law.
