Will YouTube Ever Run Out Of Video IDs?

YouTube uses a special counting system called Base64 for its video IDs. This system uses 64 different characters (numbers, capital and small letters, and two symbols) to create unique 11-character IDs for each video. This method allows YouTube to create an incredibly large number of unique IDs, far more than they will likely ever need, and also makes it easy for computers to process. They chose this system over simple counting (like 1, 2, 3) because random IDs are more secure and prevent people from easily guessing or finding other videos, especially unlisted ones.
