Dear Bharti ji,
Your query is, in annual statement some cases DOB & DOJ is shown and in some cases it is not shown. What is the reason?
DOB & DOJ is shown where it available with the department (EPFO) and not shown where it is not available. The department has recently taken a step to update its record through upload the missing data. If you have uploaded the missing data, then you will get your annual statement with updated data.
