Sometimes, they do make some sense. Earth-1983 is named after the year Spider-Man and his Amazing Frieds finished; Earth-67 is named after the year the first Spider-Man animated series premiered, etc. Actually they are not random, most of them is named after the issue and the year they appeared. For example Earth-97899, it appeared in the year 1997 and the What If issue it appeared is issue #99. Or Earth-120703. It first appeared in 2012, in July 3. Or Earth-15340. There are other examples too. So, most of them is makes sense, not random.

I know of those examples, but they fall under "sometimes." There are hundreds of realities, and most of them have just random numbers. Except almost all What If stories and thousands of other designations that actually have a meaning.
