Here's how to file Aadhaar complaints via post, website, phone

Email: You can write an e-mail to the UIDAI at help@uidai.gov.in.

These e-mails are first examined by UIDAI officials and then forwarded to concerned Regional Office/Section.

Ultimately, the grievance is disposed by replying to the complainant over e-mail, under intimation to the grievance cell.

Telephone: You can also contact UIDAI to place your queries/complaints at its toll free number 1947.

Further, you can place your complaints by sending a physical hard-copy of complaint to the UIDAI headquarters or regional offices.

Under this method, grievances are solved by replying directly to the complainant under intimation to the grievance cell.

This is the address of the UIDAI headquarters: Unique Identification Authority of India, Government of India, Bangla Sahib Road, Behind Kali Mandir, Gole Market, New Delhi-110001.

Log on to the official UIDAI portal.

Next, click on 'Contact & Support' drop down menu and click on 'File a complaint' link.

Fill up the digital form with the required details such as your enrolment ID, name, mobile number and email ID.

Select the category of complaint and enter the description of your complaint.

Finally, enter Captcha code and click on 'Submit' button.

Post the September 26, 2018 Supreme Court verdict relating to authentication of Aadhaar, there has been much confusion with respect to services where Aadhaar is mandatory and where not.

Aadhaar is no longer mandatory for services such as opening bank accounts, telecom services, and school admissions/entrance tests.

However, it is still necessary for availing government welfare-schemes and filing I-T returns (if PAN isn't used).
