What is One Time Registration (OTR)?
One Time Registration (OTR) has become mandatory across national and state recruitment commissions, including UPSC, SSC, and State PSCs.
OTR stores your primary personal, educational, and demographic credentials once, preventing repetitive entries for separate examination cycles and drastically reducing server load during peak deadline windows.
Participating Portals (UPSC, SSC, State PSCs)
Both UPSC (upsconline.nic.in) and SSC (ssc.gov.in) enforce standalone OTR identifiers. Most major State PSCs (including UPPSC, BPSC, and MPPSC) maintain separate state-level OTR portals.
Candidates must maintain accurate credentials across each portal individually, ensuring email and mobile numbers remain active for OTP delivery.
Photo, Signature & Document Sizing Specifications
Recent passport photos must be in JPG/JPEG format, sized strictly between 20KB and 50KB with clear white background and no headwear or dark sunglasses.
Signatures must be scanned in clear black ink on plain white paper (10KB to 20KB). Oversized or blurry scans account for nearly 40% of preliminary form rejections.
Step-by-Step Registration Walkthrough
Step 1: Access the official portal and select "New Registration". Enter your Aadhaar number, candidate name exactly as spelled in 10th marksheet, father's name, and date of birth.
Step 2: Verify mobile number and email via two-factor OTP authentication. Create a strong alphanumeric password.
Step 3: Fill educational qualifications sequentially from matriculation through graduation, upload required document proofs, and submit.
Common Rejection Errors to Avoid
Mismatching matriculation certificate spellings with Aadhaar card details.
Uploading selfie photos rather than formal studio passport captures with balanced frontal lighting.
Always click "Verify Details" and double-check all preview fields prior to final locking, as modification windows are strictly limited.
