Do we? Our SSN is not a unique number, and not just because the keyspace is too small for our population. (It's worse: some of the prefixes are geographically related.)
- kindredlight 5y agoSSNs have not been issued with a geographic prefix in a decade. I'm not sure if you're really suggesting two different individuals are issued the same SSN, but no, they never are. SSNs are never reused. https://www.ssa.gov/employer/randomization.html https://www.ssa.gov/employer/randomization.html https://www.ssa.gov/employer/randomizationfaqs.html https://www.ssa.gov/employer/randomizationfaqs.html
- sk5t 5y ago> SSNs have not been issued with a geographic prefix in a decade. Even if what you say were true, handwaving this as unimportant because it only affects people over the age of ten seems a bit silly.
- kindredlight 5y agoSSNs are entirely insecure as mentioned earlier in this thread. Geographic prefixes are a drop in the bucket on that front. The post that I replied to is almost entirely incorrect as it relates to available SSN “keyspace” (misnomer), uniqueness, etc.—-for which geographic prefixes and group numbers are relevant. I supplied direct sources, so no idea what your “even if what you say were true” skepticism is rooted in.
