More than Rs 980 crore has been spent alone by UIDAI in the last three years on Aadhaar enrolments and updates, while nearly 5.99 lakh Aadhaars have been cancelled for being duplicate.

Over Rs 980 crore has been spent by the UIDAI since 2019-2020 on Aadhaar enrolments and updates, while nearly 5.99 lakh Aadhaars have been declared void for being duplicate as of May 31, 2022.

As per government data, expenditure of Rs 141.60 crore, Rs 320 crore and Rs 519.9 crore were incurred in Aadhaar enrolments and updates in 2019-20, 2020-21 and 2021-22, respectively.

Officials said that the UIDAI has taken adequate steps to address duplicate or multiple Aadhaar generation issues and regular efforts are made to upgrade systems and procedures. The demographic matching mechanism has been further strengthened, biometric matching of all new enrolments is ensured and 'Face' has been included as a new modality (in addition to fingerprint and iris) for de-duplication.

Moreover, the UIDAI, through its registrars, ensures provision for Aadhaar enrollment and updates to residents. As on June 30, more than 57,000 Aadhaar centres are active across the country, while around 34,500 tablet and mobile-based machines are also functional in the field which is used for updating mobile number or email id in Aadhaar and to provide facility for Aadhaar enrolment for children under the age group of 0-5.

Besides, the UIDAI also permits residents to update their demographic details such as Name (minor change), date of birth, gender, and address online through myAadhaar portal.
