What can people find out about you from your Social Security number?

the numbers represent different data, such as your dob; state it was issued inetc, etc.

Answer

Do you mean specific to just the info revealed from the number itself? Like the first three numbers designate the state you were born in, etc.

Or do you mean...if someone knows your social security number, what can they do with it and/or find out about you?

That answer is : They can become you if they want to. They can use it to do everything you can do regarding finances, and more. Access your accounts, personal data, health records, apply and receive credit cards. Basically, with proper knowledge, they could write a book on your whole life that would be accurate. Most just choose to steal your identity for awhile, until they have financially ruined you, then move on to the next victim.
