UPSC Change of Address or Contact Details: The 7-Day Window and How to Notify the Commission

The UPSC Civil Services (Main) Examination 2026 result was declared on 5 November 2026. Candidates shortlisted for the Personality Test must carefully follow the instructions issued by the Commission, including the deadline for reporting changes in their address or contact details.

According to the UPSC result Press Note, candidates can notify the Commission of such changes within seven days of its publication. Since the Press Note was published on 5 November 2026, the calculated deadline is 12 November 2026.

Candidates can check the UPSC Mains 2026 qualified candidates list to confirm their qualifying status and prepare for the next stage.

What Does the UPSC Notice Say About Address or Contact Changes?

UPSC has clarified that it will not entertain requests to change or modify information already submitted in the application form. However, it has provided a limited exception for candidates who need to update their address or contact details.

Candidates must notify the Commission immediately through a letter or email sent to csm-upsc@nic.in, within seven days of publication of the result Press Note.

Candidates should not confuse this limited update facility with the regular DAF application-update process. For other post-result formalities, refer to What Happens After UPSC Mains Result 2026?.

Why Should Candidates Update Their Address or Contact Details?

UPSC may need to communicate important interview-related information to shortlisted candidates. An outdated postal address, mobile number or email contact can create difficulties in receiving or responding to official communication.

The Commission will release the Personality Test schedule and e-Summon Letters through its official portals. Candidates must download their e-Summon Letters online, as physical summon letters will not be sent by post.

Candidates can also check the UPSC Interview DAF guide to understand the information and formalities related to the interview stage.
