You can check your name and other details by giving your ID number and the district.
Not only your data, they present all the details of your family !
Any outsider can see the details of your family by just giving your ID !!
Names, Individual ID nos. , date of Birth of your spouse , children, others in your premises are given freely to anyone who know your ID.
I have 100s of ID Nos of our employees and many 1000s who send us CVs. !
Apart from that, web search can be automated, if you know how to do it, very easy because only ID ( numeric) and the District is involved.
