Any person who is at least 16 years of age and has a 13-digit Luxembourg national identification number (Matricule).

Application for registration

Click on the button below to start:

1. You will be automatically redirected to the Luxembourg State authentication portal (eAccess): select the authentication method that corresponds to your device.
2. Follow the steps that correspond to your authentication device.

3. Fill in the mandatory fields marked with an asterisk (*).

Your surname(s) and first name(s) are automatically read from your authentication device and cannot be changed.

Your email address is also read from your authentication device. It is important to check that it is correct and that you can still access it. Otherwise, replace it with an up-to-date address to which you do have access, as the confirmation email (required to complete the registration procedure) will be sent to that address.

The identification number is your 13-digit Luxembourg national identification number (Matricule). You will find this number on your social security card, if you have one. Make sure you enter it without any spaces or special characters (dashes, forward slashes, etc.).

1. Click on 'Register' to receive the confirmation email.

Registration confirmation

1. Check the inbox of the email address you entered during the registration procedure.
2. Open the email you received from usermanagement@security.public.lu and click on 'Confirm my registration'.

1. You will be automatically redirected to the Luxembourg State authentication portal (eAccess): select the authentication method that corresponds to your device.
2. Follow the steps that correspond to your authentication device.
3. After authentication, you will be automatically redirected to the 'Last step to register in the application' page: accept the conditions of use by ticking the appropriate box.
4. Click on 'Register'.

You will then be automatically redirected to your MyGuichet.lu account. To use the online services that require authentication, you still need to create your personal eSpace. A personal eSpace can be either a private eSpace or a business eSpace:

You will also receive a letter confirming your registration with an online public service within a few days. This letter will be sent to the address that is registered for you in the National Registry of Natural Persons (RNPP).

Sometimes, the error message 'Your National Identification Number seems to be incorrect' may appear when you try to register on MyGuichet.lu. There can be several reasons for this:

You have not entered your national identification number correctly.

Make sure that your national identification number (Matricule) is entered correctly: the Luxembourg national identification number always consists of 13 digits and must be entered without any spaces or special characters (dashes, forward slashes, etc.).

You will find your national identification number on your social security card, if you have one.

The details linked to your authentication device do not match those registered in the RNPP.

Regardless of the authentication device you are using (whether it is a physical device like the LuxTrust Scan, or the LuxTrust Mobile app), it is linked to electronic certificates that allow you to prove your identity online. These electronic certificates also contain details about you (including your surname(s) and first name(s)).

If you use your authentication device to register on MyGuichet.lu, the following step is performed for security reasons: based on the national identification number you have entered, the details linked to your authentication device are compared with the details registered for you in the National Registry of Natural Persons (RNPP). If a discrepancy is found, registration will not be possible.

Such a situation can arise if either the details linked to your authentication device or the details registered in the RNPP are incorrect or not up to date (for example, because there is a typing error in your name, or you have since got married or divorced).

If you have made sure that you have entered your national identification number correctly and you are still seeing the error message, first check the details linked to your authentication device.

If you have a LuxTrust product or a Luxembourg electronic identity card (eID), you can perform the check using LuxTrust's 'Test my certificate' service:

    • in PDF format, which you can download using LuxTrust's 'Test my certificate' service;
    • in the form of a complete, legible screenshot on which your surname(s) and first name(s) and the certificate's SSN are clearly visible;
  • a copy of your social security card;
  • a copy of your valid identity card or passport (a residence permit is not sufficient);
  • a copy of your marriage certificate (if your official surname is different from the one linked to your authentication device).
