Mar 11, 2013 Resources Sri Lanka National Identity Card Decoder I remember when I was pursuing a computer diploma, I developed a Sri Lanka identity card decoder that could extract your birthday and gender from your national identity card number. Initially, I developed it using GWBASIC, which is a rather old programming language, and I aspired to rewrite it in C#. The program is quite straightforward, and you can test it with your own NIC. (Updated to the New NIC number format as well.) Enter your NIC Number without V or X at the end. (old or new format. Ex. 912689512 or 199126890512)
