When evaluating the search results to determine if any match the search subject, don’t let odd dates of birth fool you. In the past, the DOB was not as critical a personal identifier as it is today. So when incomplete DOB information was available, the following conventions were used when creating personnel records.

If the DOB:

  • had no day, 15 was used for the day;
  • provided only the year, 01/01 was used for the day and month;
  • was missing the year, 1900 was used;
  • was completely missing, 01.01.1900 was used.

So if all other identifying information matches the source document you are working with, but the DOB looks wrong in one of the ways shown above, then confirm the record. The Global Index Approvers will verify the accuracy of this selection.
