What is TNPSC One Time Registration (OTR)?
Quick answer
OTR is TNPSC's mandatory candidate profile on tnpscexams.net. You register once for ₹150, it stays valid for 5 years, and every TNPSC application you submit starts from this profile.
Keep your OTR details accurate: name, community and education entered there are checked against your original certificates during verification, and mismatches can cost you the selection.
Worth knowing
- One-time fee of ₹150, valid for 5 years
- Register only on tnpscexams.net, linked from tnpsc.gov.in
- Finish within 48 hours or the incomplete registration is deleted
- Name and date of birth must match your SSLC certificate letter for letter
- Photo (20-50KB) and signature (10-20KB) in exact TNPSC specification
- Exams still charge their own examination fee unless you are fee-exempt
What you fill in
OTR captures the identity TNPSC will verify you against for the next five years:
- Personal details exactly as your SSLC certificate reads: name, date of birth and parentage
- Community and the certificate number it is claimed under
- Education records from SSLC onwards with register numbers, boards, years and medium of instruction; the Tamil-medium entries here are what your PSTM claim is checked against
- Photo (3.5×4.5cm, 20-50KB) and signature (3.5×1.5cm, 10-20KB) uploads
- A personal email and mobile number you will still control in five years
Why OTR matters more than it looks
Applications take minutes because OTR already holds your profile, but that convenience cuts both ways: an error entered once repeats in every application, and it usually surfaces at certificate verification, after you have cleared the exam. Corrections are possible only in windowed edit periods, so entering it right the first time is free while fixing it later can wait months.
