Complete Guide: UPSC One Time Registration (OTR) Photo & Signature Rules
The Union Public Service Commission (UPSC) recruits officers for India's prestigious civil services (IAS, IPS, IFS, IRS), defense services (NDA, CDS, AFCAT), engineering services (ESE), and medical services (CMS). Under the modern One Time Registration (OTR) system on upsconline.nic.in, candidates register their biometrics and personal details once for all future examinations.
Because OTR profiles are permanent and remain linked to your candidate ID across multiple exam attempts, UPSC enforces rigorous photo and signature validation standards. Submitting non-compliant images can lock your profile or delay application submission during peak deadlines.

3. Why 100% In-Browser Privacy Matters for UPSC Aspirants
As an aspirant for the highest civil and administrative services of the nation, protecting your digital identity is paramount. Uploading your signature and photograph to unverified external cloud servers exposes your personal information to data harvesting.
