How to read SIC 99999
SIC 99999 reads as division 99 (activities of extraterritorial organisations and bodies), group 999, class 9999, then the full five digits, inside section U, activities of extraterritorial organisations. A company picks its own codes, up to four, and Companies House does not check them, so 99999 is the company's own description of what it does, and 98,777 list it first where 104,237 list it anywhere.
