UPSC Mains DAF 2026: Dates, Form Filling Process & Required Documents

The UPSC Civil Services Examination process does not end with qualifying the Preliminary Examination. Candidates who clear the Prelims must also complete the UPSC Mains Detailed Application Form (DAF) to become eligible for the Mains stage. Since the UPSC Civil Services Mains Examination 2026 is scheduled to begin from 21 August 2026, qualified candidates will be required to submit the DAF within the timeline notified by the Commission after the Prelims result.

Many aspirants lose marks or face verification issues later because of incorrect category claims, incomplete uploads, wrong optional subject selection, or document mismatches in the DAF form. Understanding the UPSC Mains DAF 2026 process early helps you avoid mistakes during submission and complete all formalities smoothly before the Mains examination.
