what happens when they run out of letters?

the 3-letter tickers are from a different era.... nowadays the usage of tickers is more of a "legacy" tradition rather than a current necessity. as such they're no longer limited to 3 characters. and the characters don't have to be related to the actual name. for example a company named alphabet is trading on nasdaq under the ticker "googl". it has 5 characters, not 3, and (almost) none of them appear in the name of the company (used to, but not anymore).
