NPCI adopts Verhoeff Algorithm for validation of Aadhaar Numbers

          The NPCI Aadhaar Seeder is the bridge connecting the Government Departments and the Bank Account Holders for receipt various Government subsidies, scholarships etc.

          Due to the LPG subsidy rollout program in the last couple of months, the number of Aadhaar numbers being seeded in Bank Accounts and NPCI Database has zoomed up drastically.

          It might be noted that Aadhaar is just another number, if the Biometrics validation of the Resident is not done.

          At present, basing on the Aadhaar Number Card, the seeding is done on Bank accounts or with LPG companies. The actual biometric validation has not yet commenced.

          Hence, it becomes still more important to capture the correct Aadhaar number.

          Recognizing that the Aadhaar number will be manually keyed in numerous occasions, UIDAI had adopted the Verhoeff Algorithm method, to minimize data-entry mistakes.

          The Algorithm logic is in public domain. However, computation cannot be done manually, and only computer programs are capable of validating a number in the Verhoeff Algorithm method.

          NPCI vide its circular dt. July 09, 2013, advised all banks which are part of the NACH-APB system to implement the Verhoeff Algorithm in their systems to validate Aadhaar numbers before seeding the same in customer accounts. If this is not done, any invalid Aadhaar number will be rejected by NPCI mapper with the reason, ‘Invalid Aadhaar No_ Verhoeff Checksum validation failed’.
