NRIC Recovery

Year of birth:

Last 4 characters of NRIC:

This open-source tool demonstrates that masking NRIC numbers by showing only the last 4 characters (e.g., "####123A") provides limited security value. Given just the birth year and these 4 characters, the full NRIC can be recovered with minimal computation.

NRIC numbers should not be treated as sensitive information—they are identifiers, not authenticators. Please refer to MDDI's post on NRIC for more information.
