We only use the 7 digits in the middle — omit the first and last letter.
🔒 This calculation happens 100% in your browser using JavaScript. Your NRIC/FIN number is never sent to any server, never stored, and never logged — not by us, not by anyone. You can disconnect from the internet before typing it in and this tool will still work.

Your Lucky Number

Your Energy Number

How It Works

A Singapore NRIC/FIN has 7 digits between the leading and trailing letters (e.g. S1234567D). We only ever use those 7 digits — never the letters. Your Energy Number is a mathematical fingerprint of the full 7-digit sequence. Change even one digit and the number changes completely.

Good luck on your lucky NRIC number!
