China and Japan also have numerical stock tickers, e.g. Sony's ticker 6758 instead of e.g. SONY. I guess numeric IDs like that were a consequence of early tech making it hard to deal with more complex character sets ... maybe the association lives on in those cultures? There's also deeper associations with numbers like 8 representing luck, 4 meaning death etc.
