The new UPSC portal has replaced the old OTR system with a new 4-step system. Old OTR data does not carry forward, so candidates have to create a fresh profile on the UPSC online portal.

Who Can Register for UPSC CSE 2027?

UPSC Registration 2027 Important Dates

Candidates should keep track of the important UPSC Registration 2027 dates to complete the application process and prepare for the examination on time. 

What is Universal Registration Number (URN)?

Universal Registration Number, or URN, is a unique number created after a candidate registers on the UPSC Online Application Portal. This URN is common for all UPSC examinations and has to be created only once in a lifetime.

The URN stays the same for future UPSC exams. But the application number changes from one exam to another after you fill the exam-specific form.

What is UPSC OTR?

The old One Time Registration, or OTR, has been replaced on the new UPSC portal. UPSC now uses a new system that includes Account Creation, Universal Registration, Common Application Form, and Exam Specific Form.

This means candidates should not depend on old OTR details. They must make a fresh profile on the new UPSC online portal.

What is Common Application Form (CAF)?

Common Application Form, or CAF, is the part of the UPSC portal where candidates fill basic details and upload important documents. This form is common for different UPSC exams.

UPSC has said that required information and supporting documents for claims like date of birth, educational qualification, and other details may be asked with the URN and CAF. If required details or documents are not given, candidature can be cancelled.

What is the Exam Specific Form?

The Exam Specific Form is the last module of the UPSC application portal. This part is filled only when the notification for a particular exam is open.

For UPSC CSE 2027, this form will be available only during the application window. After filling this form, the candidate gets an application number for that exam.

How to Retrieve Forgotten Registration Details

If a candidate forgets login or registration details, the first step should be to use the recovery options available on the UPSC online portal. Since the new system is based on account creation and URN, candidates should keep their email ID, mobile number, URN, and application number safe.
