Verify your 12-digit Aadhaar number quickly and securely
Your Aadhaar data remains private and is verified locally.
This tool validates Aadhaar numbers using the Verhoeff algorithm - the same method used by UIDAI. The validation is performed entirely in your browser and no data is sent to any server.
Aadhaar is a 12-digit unique identity number issued by the Unique Identification Authority of India (UIDAI) to residents of India. It captures biometric data including fingerprints and iris scans, along with demographic information.
Validating an Aadhaar number is crucial for many purposes, from KYC verification to ensuring the number provided is genuine. Each Aadhaar number contains a checksum digit that helps verify its authenticity using the Verhoeff algorithm.
Our validation tool implements the complete Verhoeff algorithm—the same method used by UIDAI—to verify the mathematical integrity of any Aadhaar number. All validation is performed locally in your browser for complete privacy and security.
Our validator uses the Verhoeff algorithm, the same checksum algorithm used by UIDAI, to validate the mathematical integrity of an Aadhaar number. This works by checking that the last digit of the number (the checksum) correctly validates against the rest of the number according to a specific formula.
Absolutely. This tool performs all validation entirely within your browser. The Aadhaar number you enter is never sent to our servers or stored anywhere. This client-side processing ensures complete privacy and security of your sensitive information.
Validating an Aadhaar number is useful in many situations, such as when collecting customer information for KYC purposes, verifying employee details, or ensuring the number provided to you is at least correctly formatted before proceeding with official verification.
