How to Register for TNPSC OTR, Step by Step

One Time Registration (OTR) is the profile every TNPSC application starts from. You do it once, it stays valid for five years, and every detail in it is checked against your original certificates at verification. Do it slowly and correctly once.

  1. Step 1
    Keep these ready before you start
    Your SSLC marksheet (for name, date of birth and registration details), community certificate number, a valid personal email and mobile number, your resized photo (20-50KB) and signature (10-20KB), and a way to pay ₹150 online.
  2. Step 2
    Open the official portal and choose One Time Registration
    Go to the TNPSC exams portal (tnpscexams.net, linked from tnpsc.gov.in), click One Time Registration, then New User. Never register through third-party sites.
  3. Step 3
    Fill basic details exactly as your certificates read
    Name, date of birth and parentage must match your SSLC certificate letter for letter. The community you enter must match your community certificate. Mismatches surface at certificate verification, not now, and can cost the selection.
  4. Step 4
    Upload photo and signature in the exact specification
    Photo: 3.5×4.5cm, 20-50KB JPEG, white background, taken within 3 months. Signature: 3.5×1.5cm, 10-20KB, normal running handwriting. Use our free resizers to hit the sizes exactly.
  5. Step 5
    Enter education records from SSLC onwards
    Add every qualification with register numbers, boards, years and medium of instruction. Tamil-medium entries here are what your PSTM claim is checked against later.
  6. Step 6
    Pay ₹150 and finish within 48 hours
    The registration fee is ₹150, paid online. Complete the whole registration within 48 hours of starting, incomplete registrations are deleted after that window and you start over.
  7. Step 7
    Save your OTR ID and verify the profile
    Note your user ID, set a password you will remember for years, and re-read the profile once fully. Corrections later are possible but windowed; getting it right now is free.
Worth knowing
  • Register well before a notification you care about, portal traffic spikes near deadlines
  • Use a personal email you will still control in five years, not a college or office address
