Welcome to UIDAI Developer Portal. This portal is targeted to developer community who are interested in building Aadhaar enabled applications. If you are not a developer or new to Aadhaar and UIDAI (Unique Identification Authority of India), visit uidai.gov.in. Unique identification project was initially conceived by the Planning Commission as an initiative that would provide identification for each resident across the country and would be used primarily as the basis for efficient delivery of welfare services. It would also act as a tool for effective monitoring of various programs and schemes of the Government.
