To calculate age from ID number, the following formula can help you. Please do as this:

Enter this formula:

=DATEDIF(DATE(IF(LEFT(A2,2)>TEXT(TODAY(),"YY"),"19"&LEFT(A2,2),"20"&LEFT(A2,2)),MID(A2,3,2),MID(A2,5,2)),TODAY(),"y") into a blank cell where you want to calculate the age, and then drag the fill handle down to the cells you want to apply this formula, and the ages have been calculated from the ID numbers at once, see screenshot:

Hello, Mthembu

Yes, if the year in ID number is less that current year it will be considered as 20, if year is greater than current year will be considered as 19.
For example, this year is 2022, ID number 1009132310091’s birth date is 2010/09/13, the ID number 6802172309334’s birth date is 1968/02/17.

Thank you!

I also have the similar issue. Is there a way to distinguish between such scenario?

I think you are missing the point. If a person was born in 1920 (102 years old) , their ID would start with 20. A child born in 2020 (2 years old) will also start with 20. How do you determine now if the person is 102 or 2 years old by looking at the first 2 digits ?
