The original UPSC ESE 2027 application deadline of 6 October 2026, 6:00 pm IST (12:30 UTC), has passed. The Engineering Services Preliminary Examination is scheduled for 31 January 2027. Applicants should retain their submitted application records and follow the official examination page for later notices.
Original guide sources checked: 1 October 2026. Application-status sources checked: 6 October 2026, 11:28 pm IST. This is an independent NaukriAlert24 guide, not a UPSC website or an eligibility decision.
Official amendment check: At 11:28 pm IST on 6 October 2026, no deadline-extension notice was found in the UPSC examination and notification pages, homepage, active-examination list, highlights and What’s New pages checked. Some listing pages showed older update dates and different versions across checks, so this check is not exhaustive. Follow any later official UPSC notice.

After the original application deadline
- Keep your records: retain your URN, examination-specific Application Number, submitted form, confirmation and any fee-payment acknowledgement. These are practical record-keeping tips.
- Check exam-specific submission: the reusable account, URN and CAF modules are separate from the examination-specific form. Registration alone should not be treated as proof that an ESE 2027 application was submitted.
- Fee and incomplete-form rules: the original notice says applications without the prescribed fee or payment mode are rejected unless fee remission is claimed (page 17). It also says incomplete or defective applications are rejected and representations about that rejection will not be entertained (page 19). The notice does not provide a separate later window to complete an incomplete application or its payment.
- Follow official notices: check the examination page for later instructions and use the e-Admit Card arrangements in the official notice.
Source: UPSC ESE 2027 notification, pages 1, 3, 17 and 19. A payment acknowledgement alone should not be treated as confirmation that an incomplete form has been accepted.
Historical checklist: the original application guidance below is retained for reference. Its preparation and submission steps relate to the original application window; later official UPSC notices take priority.
Understand the four modules and your two numbers
The process has four modules: account creation, Universal Registration, Common Application Form (CAF), and the examination-specific form. The first three are reusable; the fourth is completed within the examination’s application window.
- URN: your Universal Registration Number stays the same across UPSC examinations.
- Application Number: identifies the particular examination application. Keep both numbers.
These distinctions are explained on page 1 of the official ESE 2027 notification.
Photo, signature and correction rules to check first
- Photo: CAF requires an uploaded photograph and a live photograph.
- Signature: sign three times, one below another, in black ink on plain white paper. Upload a clear, legible image.
- After submission: applications cannot be withdrawn or corrected.
- URN edits: the one-time profile update does not change an already-submitted application; changes apply to later applications after re-locking the profile.
Source: notification pages 2–3. Use the portal’s current “Instructions and FAQs” for photo, signature and document-upload specifications.
Historical preparation checklist
The following are practical preparation tips. They do not replace UPSC’s instructions or create additional requirements.
- Read eligibility before filling fields. Bookmark the relevant sections of the notice. Write down any question about your qualification or category so you can resolve it before submission.
- Compare your records. Put your identity and education records side by side. Check spelling, dates and certificate details against the information you intend to enter. Do not guess how to resolve a mismatch.
- Name files clearly. Use names such as “photo-final” and “signature-final” so an older scan is less likely to be selected accidentally. Keep personal documents in a private folder.
- Open each file before uploading. Look for missing edges, blur, glare or unreadable text. Check the current permitted format and size on the portal rather than copying specifications from an old exam guide.
- Prepare your device. Test that the camera works and choose a well-lit place. Leave time to solve a browser or upload problem instead of starting near the closing hour.
Historical final review before submission
Set aside a separate review pass. Read the completed form slowly rather than immediately clicking through after typing.
- Is the examination name and year the one you intend to apply for?
- Have you compared personal details with the supporting records?
- Have you checked each qualification, category and other claim you entered?
- Are the selected options and centre details intentional?
- Does each uploaded file contain the correct document and remain readable?
- Have you checked the applicable fee and payment instructions in the official notice and portal?
- Have you resolved any warning or incomplete section shown on screen?
After submission, save the confirmation, a copy of the submitted form and any payment acknowledgement provided. Keep these together so you can find them quickly if a later query arises. Avoid sharing screenshots containing personal details in public groups.
Application-window helpdesk details
The original notification listed UPSC application helpdesk numbers 011-24041001 / 011-40303444 and upscsoap@nic.in, with hours of 10:00 am–5:30 pm on working days during 16 September–6 October 2026 (page 4). That stated support period should not be assumed to extend beyond the application window.
If you have a submission or payment query, retain the exact error message, time and transaction acknowledgement, and consult the current official UPSC instructions. Do not send anyone your password or one-time code. Do not assume another payment after the original deadline will complete an incomplete application.
