About Sri Lanka NIC Information Finder

Our Mission

Our mission is to provide a completely free, highly accessible, and privacy-first NIC decoder. We believe that basic utility tools shouldn't compromise user data, which is why this application runs entirely within your browser without sending sensitive information to external servers.

How We Decode NIC Numbers

Our algorithm accurately reverse-engineers the standard format established by the Sri Lankan government. We rely on the following mathematical extractions:

• Birth Year Extraction: Extracting the first 2 digits of the old 9-digit format (assuming a 1900s baseline) or the first 4 digits of the new 12-digit format.
• Gender Determination: Analyzing the day-of-year segment. If the value is above 500, the gender is marked as Female. Otherwise, it is Male.
• Day-of-Year to Calendar Date: Subtracting 500 (if female) to get the raw day of the year, then adding this number of days to January 1st of the birth year, carefully factoring in leap years.
• Age Calculation: dynamically computing age based on the extracted birthday compared to the current date.
