how many numbers can be made with a social security number?
- 1 decade agoFavorite Answer
A SSN has nine digits,but we can use 10 digits[0-9]
Keep in mind that we can't use the digit zero at the front.
Therefore, there are 9 possibilities for the first digit and 10-digits for the rest.
Therefore,there are 900 million possibilities of SSN.

An SS# has 9 digits between 0 and 9 (i.e. 10 possibilities for each).
The number of possible social security numbers is then 10^9, i.e. a billion.

There are nine digits in a SSN, and if you allow all zeros, the number is 10^9 (one billion).
