A gazette notification for Aadhar name change is a legally recognized document essential for a complete name change in Aadhar card, especially when the change is extensive. The Unique Identification Authority of India (UIDAI) mandates this as legal proof of your new name. To obtain it, you must create a name change affidavit, publish a newspaper ad, and submit the documents to the Department of Publication to get your new name published in the Gazette of India. This final document then serves as a valid Proof of Identity for updating your Aadhar card at an Aadhar Enrolment Centre.
