UPSC Engineering Services Examination 2027: Application Form, Eligibility, 480 Vacancies & Dates

The UPSC Engineering Services Examination (ESE) 2027 notification is out, and the application window is open from 16 September 2026 to 6 October 2026 at 6:00 PM. The Union Public Service Commission (UPSC) has stated an expected 480 vacancies, including 19 vacancies for Persons with Benchmark Disabilities (PwBD). The Preliminary Examination is scheduled for 31 January 2027, while the Main Examination is scheduled for 18 June 2027.

This guide focuses on the current 2027 notification rather than an expected schedule. It brings the application process, age limit, educational qualification, fee, vacancy position, exam pattern and document checks together so you can verify the important details before submitting the form.

UPSC Engineering Services 2027: Quick Overview

The vacancy figure is an estimate, not a final guaranteed number. UPSC states that the number of vacancies is liable to alteration. Candidates should therefore use the current notice as the controlling source and recheck the official page for any later update.

UPSC Engineering Services 2027 Important Dates

The notification gives a clear calendar for the main stages of the examination. The application period starts on the notification date and closes at 6:00 PM on 6 October 2026.

Do not rely on an older article or a coaching-calendar date for the application deadline. The live UPSC notification is the safer reference because it specifies the date and exact closing time. The same notice says the eligible candidates’ e-Admit Cards will be made available through the online portal and will not be sent by post.

Vacancies and Engineering Disciplines

UPSC expects approximately 480 vacancies in the Engineering Services Examination 2027. The notice explicitly says that this number is liable to alteration, so it should be treated as a planning figure rather than a final appointment count.

The four discipline categories are important because ESE eligibility and the discipline-specific papers are tied to the engineering category you apply under. The notification’s participating-services section also shows why candidates should read the post/service details rather than assume that every engineering graduate is eligible for every service under the examination.

UPSC Engineering Services 2027 Eligibility

Eligibility has several parts. A candidate needs to satisfy the nationality provisions, age rule, educational qualification and the other conditions of the notified services/posts. Admission is provisional, and UPSC states that the issue of an e-Admit Card does not by itself mean that final eligibility has been cleared.

A useful practical rule is to check the exact service or post you are interested in, not just the broad label “ESE eligible.” The examination has four engineering categories and several participating services/posts, and the notice contains additional conditions for individual routes.

Age Limit and DOB Rules

For the standard ESE 2027 age rule, the candidate must have attained 21 years and must not have attained 30 years on 1 January 2027. UPSC translates that into a date-of-birth window: the candidate must have been born not earlier than 2 January 1997 and not later than 1 January 2006.

The DOB check is especially important because UPSC says the accepted date of birth is the one recorded in the Matriculation or Secondary School Leaving Certificate or another certificate recognized under the notice. It specifically warns against substituting documents such as a horoscope, affidavit or a municipal birth extract where the prescribed certificate is required.

The application instructions also say that once the date of birth has been submitted and entered in the Commission’s records for the examination, a later change is not allowed. This is why it is worth checking your DOB against the original qualifying document before you submit the form.

For a separate explanation of document-based DOB checking in government recruitment, see our Date of Birth Proof for Government Jobs in India guide. For date-entry mistakes in online forms, our Age Calculator for Forms guide is also useful.

Educational Qualification

The minimum educational qualification is not simply “any graduation.” For the standard rule, a candidate must have obtained a degree in Engineering from a qualifying Indian university or institution, or satisfy one of the alternative engineering qualifications specifically listed by UPSC.

• A degree in Engineering from a university or institution recognized under the conditions set out in the notice.
• Sections A and B of the Institution Examinations of the Institution of Engineers (India), subject to the notice’s conditions.
• Certain recognized foreign engineering degrees or diplomas, under the conditions stated by the Government.
• Specified membership examinations of the Institution of Electronics and Telecommunication Engineers (India), the Aeronautical Society of India, or the Institution of Electronics and Radio Engineers, subject to the eligibility restrictions stated in the notification.
• For certain specified services/posts, the notice also provides special M.Sc. qualification routes in subjects such as physics, radio communication, electronics or telecommunication.

There is an important date-related qualification warning in the 2027 notice: it states that certain degrees or certificates obtained from particular institutions by candidates who took admission after 31 May 2013 are not admissible, and other institutional-qualification cases are subject to the specific conditions stated by UPSC. Candidates using a non-standard qualification should therefore read the relevant clause rather than assuming an old equivalency rule still applies.

Application Fee

The prescribed examination fee is ₹200, payable through the modes specified by UPSC. The notice states that female candidates and candidates belonging to SC, ST and PwBD categories are exempt from the fee.

UPSC says the fee can be paid through net banking or the prescribed card/UPI methods listed in the notice. Payment through an unsupported method can lead to rejection, so use the options displayed by the official portal.

How to Fill the UPSC ESE 2027 Application Form

The current application system uses a common online structure rather than a simple one-page form. UPSC describes four modules/cards: account creation, Universal Registration, Common Application Form and the examination-specific module.

1. Create or access your UPSC Online account. Start at upsconline.nic.in and follow the portal’s current instructions.
2. Generate your Universal Registration Number (URN). UPSC says the URN is common to examinations and is generated after registration. Keep it securely with the application details.
3. Complete the Common Application Form (CAF). Enter your personal details, date of birth, educational information and other requested data carefully.
4. Upload the required photograph and signature. The 2027 notice requires both an uploaded photograph and a live photograph capture while filling the CAF. It also says the signature should be made three times on plain white paper using black ink and uploaded clearly.
5. Complete the Engineering Services examination-specific module. This is where the examination-specific choices, fee and centre details are handled according to the portal’s instructions.
6. Provide the required supporting information. UPSC may require evidence for DOB, educational qualification, category, age or fee concession and other claims.
7. Review everything before final submission. The notice states that the application cannot be withdrawn after submission and no correction or modification in application fields is allowed after submission.
8. Retain the Application Number and URN. The Application Number is examination-specific; the URN remains the common registration reference.

There is a useful distinction between the URN profile and an already submitted examination application. UPSC provides a one-time facility to update or modify the URN profile, but the notice makes clear that changes to the profile do not flow back into applications that have already been submitted. The updated profile applies to later applications after the profile has been successfully re-locked.

Documents and Details to Keep Ready

Preparing the documents before opening the application can reduce last-minute errors. The notification and its application instructions identify several categories of supporting information.

• Matriculation/Secondary certificate: keep the document that establishes the accepted date of birth and make sure the name and DOB you enter match it.
• Engineering qualification: keep the relevant degree, certificate or other accepted qualification evidence.
• Category documents: where applicable, keep SC/ST/OBC/EWS/PwBD or other supporting certificates in the prescribed form and within the notification’s dates.
• Photo ID: the notice lists Aadhaar, Voter Card (EPIC), PAN Card, Passport, Driving Licence or another government-issued photo ID as examples.
• Photograph and signature: follow the current portal instructions for size, clarity and upload requirements rather than using a file prepared for an older recruitment form.
• Active email address: UPSC says an active email ID should be provided because the Commission may use electronic communication during different stages of the examination.

For reserved-category or concession claims, do not wait until after submission to discover that a supporting certificate does not meet the notification’s conditions. The 2027 notice includes specific date and validity requirements for some certificates, including OBC-NCL and EWS documents.

ESE 2027 Exam Pattern and Marks

The examination is conducted in three stages. Stage-I is the Preliminary Examination, Stage-II is the Main Examination and Stage-III is the Personality Test/Interview. The marks at the Main and Personality Test stages contribute to the final result under the rules described by UPSC.

That gives Stage-I a total of 500 marks and Stage-II a total of 600 marks, followed by a 200-mark Personality Test/Interview. UPSC also specifies negative marking for wrong answers in the objective papers: one-third of the marks assigned to the question is deducted for a wrong answer. Leaving a question blank does not attract that penalty.

Common Application Mistakes to Avoid

• Using an expected 2027 date instead of the current notification. The official notification is already available and gives the application and examination dates.
• Calculating age by birth year alone. ESE uses the age position on 1 January 2027 and gives an exact DOB window.
• Entering a DOB that differs from your accepted certificate. UPSC places particular importance on the recorded date of birth and does not permit a later change to it.
• Choosing the wrong engineering category. The four categories are Civil, Mechanical, Electrical, and Electronics & Telecommunication Engineering.
• Assuming every engineering qualification is automatically accepted. The notice contains specific qualification routes and restrictions for some institutional credentials.
• Waiting until the final hour to upload the photograph or signature. The current process includes live photograph capture and a specific signature format.
• Assuming a submitted application can be edited later. UPSC states that no addition, deletion or modification is allowed in the submitted examination application.
• Confusing an e-Admit Card with final eligibility clearance. UPSC says admission is provisional and final document verification occurs later in the process.

Final Takeaway

UPSC Engineering Services 2027 is now a live examination cycle, with applications open from 16 September to 6 October 2026. The current notification sets the Preliminary Examination for 31 January 2027 and the Main Examination for 18 June 2027, and places the expected vacancy count at approximately 480.

The most important checks before submitting the form are your engineering qualification, the exact 21–30 age rule and DOB window, the correct engineering category, any applicable concession documents, and the accuracy of your personal information. The online process uses account creation, URN, CAF and an examination-specific module, with photograph and live-photo requirements plus a specific signature upload process.

Because UPSC does not allow post-submission corrections to the examination application, a careful document check before final submission is more useful than trying to fix a mistake afterward. Use the official notification and UPSC Online portal for the final application.
