Registration in the commune

To do so, you have to notify  the commune - these are different local neighborhoods with their own names and administration. Within 3 days after moving to Luxembourg you have to come to the local administration with following documents:

  • A valid travel document - for example, a passport with entry stamps.
  • Proof of residence — a long term rental agreement. However, if you have an employment contract for 4 years, the rental agreement is not necessarily supposed to be for the same duration. But Airbnb accommodation is not suitable, unless it is a long-term rental and you can prove it.
  • The original papers of the residence permit approval that you received prior to your arrival in Luxembourg.
  • In case you arrive with a spouse and children, the marriage certificate and the children's birth certificates.

In order to register at the place of residence you will need to come to the commune center in person. After the application is processed, the staff member will give you:

  • The social security number (i.e. matricule) that consists of your date of birth in year-month-day format and five other digits.
  • Declaration of Arrival — this paper serves as a work permit and permission to stay in Luxembourg until an official residence permit is issued.
