we went through the code and there are no EORI number yet, or any place to put it.
Do you have a wish written of this and the target audience ? I think this is mainly for exporting from UK -> EU ?
Maybe you can use some field from the Company Info?
AS far as remember EORI code is for every importer/exporter both for persons and companies. Even if you buy from Aliexpress you use EORI.
There are some fields that can be used, if, you are not using them but then to get them to some documents can be tricky if they are not done for the form
