A check digit is a form of data validation used to determine the accuracy of a primary data number. In this case, a check digit could help prevent the transposition and typographical errors seen in the Social Security numbers by adding an extra digit that is calculated from the other digits. This makes it easier to detect errors because if the numbers are entered incorrectly, the check digit will usually not match up, indicating a mistake. Batch checks, validity checks, and sequence checks do not directly address the specific issue of ensuring the numerical accuracy of each individual Social Security number entered.
