My Social Security number is the same?

Question

except for the last two digits of my brothers. He has less than honorable character to say the least and I want to know if there is a way I can protect my ssn?

Answer 1

Have one of the credit bureaus put a lock on it.

The first 3 digits are going to be the same since registered for a SS# at the same city or state.   I assume the others are the same since they were both gotten at the same time.
