While filling the Pan card application, you are requested to provide your first name, middle name and surname. Surname is only mandatory among it. You may not know the order in which you have filled each of these 3 names.
To find out the surname among it from your pan card, check the fifth character of your PAN. Fifth character of PAN is the first letter of your surname. Suppose, if it is ‘T’, the name which starts with the letter ‘T’ has been given as surname in the pan application form.
