The Company Code is the code used on the Infront Analytics platform to identify a company. On the web, it is displayed in the page header of the Companies interface.
The Company Code is necessary to query any data item with a Quick report or a Time series. However, in most cases, you do not need to specify it: the wizard will take your input defined as a company name/ISIN code/ticker and convert it into a Company Code.
Note that the Company Code is still a mandatory step when uploading a company list from Excel.
