The Unique Identification Authority of India (UIDAI) has introduced significant amendments to Aadhaar enrolment and update processes through the Aadhaar (Enrolment and Update) First Amendment Regulations, 2026. Key changes include an expanded list of acceptable documents, such as e-Voter IDs, ration cards, and educational certificates, which must be valid and verifiable. The rules have been simplified for children, with specific provisions for those under five years requiring a birth certificate and documentation from guardians. For children aged 5-18, the Head of Family-based enrolment is encouraged. Furthermore, the amendment clarifies Aadhaar validity periods for Overseas Citizenship of India (OCI) cardholders (10 years), Long-term Visa (LTV) holders (until visa validity), and citizens of Nepal and Bhutan (10 years). Transgender identity documents are now accepted for updates, and legal guardianship documents are recognized for individuals under guardianship. Special provisions have also been made for vulnerable groups, including children in care institutions and HIV/AIDS affected persons.
