Question 227895: Social Security numbers are in the form ###-##-####, where each symbol represents any number 0-9. How many Social Security numbers are possible using this format? Will we ever run out of Social Security numbers?
Would it be 90 factorial? Thank you.

There are 9 digits, so they could be a nine-digit number. The hyphens don't count.
That's 10^9 = 1,000,000,000 numbers (from 0 to 999,999,999)

We have no way of knowing if we will "run out" of SS numbers. Arithmetic cannot predict the future.
