Aadhar Address Change Guide is a free Android application developed by Tahmin Tradrs. The app belongs to the Education & Reference category and provides guidelines for Indian citizens to update their Aadhar card. The Aadhar card is a unique 12-digit identification number issued by the Unique Identification Authority of India (UIDAI) based on the individual's biometric and demographic data.

The app offers several features, including applying for an Aadhar card online, changing the address on the card via online or offline mediums, checking the status of the Aadhar card, downloading an e-Aadhar card, verifying email/mobile numbers, and locating enrollment centers for Aadhar card. It also provides information on how to check the Aadhar card's bank linking status and update history. However, the app is not an official UIDAI app and is built as a public service to help Indian residents manage their Aadhar information using their smartphones from the comfort of their homes.
