How to find the identifier of my personal eSpace (private or business)
Last update
On MyGuichet.lu, there are some procedures that require the electronic signature of 2 people. Some of these procedures (e.g. tax returns via the electronic assistant) require a double signature with a transfer to another eSpace. This means that the person who first signs the procedure in their personal space (private or business) must send it to the personal eSpace of a second person so that they can sign the procedure using their own LuxTrust product.
If the second signatory is:
- a natural person, they will need the identifier of their private eSpace for the transfer;
- a legal person (e.g. a trust company), the identifier of their business eSpace must be used for the transfer.
You cannot see the eSpace identifier in the MyGuichet.lu mobile app. You must therefore use the browser version of MyGuichet.lu.
How to proceed
- Private eSpace
- Business eSpace
To find the identifier of a private eSpace, first log on to MyGuichet.lu.
If you only have a private eSpace, you will be taken to its homepage. Click on your name in the header: a drop-down menu will open, in which you will find, among other things, the identifier of your private eSpace.
If you also have one or more business eSpaces, you will first be taken to the eSpace selection page. You will find the identifier of your private eSpace just to the right of your name.
The identifier of a private eSpace always consists of:
- the abbreviation PP (which stands for 'personne physique' = natural person');
- a dash; and
- a combination of 6 capital letters and numbers.
It is case sensitive.
You can simply copy the eSpace identifier by clicking on the small symbol next to it.
The eSpace identifier is not the same as the user certificate number.
To find the identifier of a business eSpace, first log on to MyGuichet.lu.
If you only have one business eSpace, you will be taken to its homepage. Click on the name of the business eSpace in the header: a drop-down menu will open, in which you will find, among other things, the identifier of the business eSpace.
If you also have a private eSpace or several business eSpaces, you will first access the eSpace selection page. You will find the identifier of the business eSpace just to the right of the heading.
The identifier of a business eSpace always consists of:
- the abbreviation PM (which stands for 'personne morale' = legal person');
- a dash; and
- a combination of 6 capital letters and numbers.
It is case sensitive.
The eSpace identifier is not the same as the user certificate number. You need the certificate number if someone wants to add you to a business eSpace.
