How are SSN type data generated?

#1

Could SSN data potentially collide with real SSN data causing privacy PII concerns?

#2

SSNs are generated as random combinations of numbers, so it is possible some of them will be real. You can guarantee that they are not real by replacing the first number with 9. You can do this by applying the following inline formula using the f(x) button:

this.gsub(/^\d{1}/, '9')
