A representative of University Advancement contacted me and wanted to know if printing a person's birthday (MM/DD/YYYY) and the last 4 digits of the person's SSN on pledge cards was acceptable.
Printing the last 4 digits isn't a good idea, because in the context of a university, the first 5 digits are often easy to guess based on the state and the year the person was born. So for instance, our incoming freshmen there's a very good chance that the first 3 digits are 223- through 231- if the SSN was issued in Virginia. The second 2 digits are a 'group number', and with some sleuthing you can find what likely group numbers in a given year in a given state were being issued.
