GATE 2027 registration now closes on October 5, after an extension. Many engineers are rushing to finish error‑free forms this week. Rejections still happen for small misses, despite the extra time. Use this focused checklist to secure documents, images, cities, and payments before submission.
Prioritise if you are final‑year, reappearing, or targeting Public Sector Undertaking (PSU) roles. Regular applications end October 5; late‑fee submissions run till October 12. The correction window is October 14–21 for limited edits. Plan now so you don’t rely on fixes later.

Register through GOAPS using your verified DigiLocker profile. Keep UPI, card, net banking, or wallet ready, because payment is non‑refundable. Avoid peak hours; early mornings reduce payment timeouts. Download the application PDF immediately and do not delete DigiLocker after fee payment.
Use a colour passport photo on a white background. Upload JPEG/JPG between 200×260 and 530×690 pixels, 5–600 kB, with the face covering 60–70 percent. Sign in dark blue or black ink, 250×80 to 580×180 pixels, 3–300 kB. Avoid sunglasses, glare, headcovers, or digital signatures.
Upload SC or ST certificate now, if applicable. Upload Unique Disability ID or PwD certificate to the GATE2027 DigiLocker folder, as instructed. OBC‑NCL and Economically Weaker Section certificates are usually verified at admission, not during application. Keep a valid government photo ID and consistent personal details across documents.
Choose six examination cities from one zone, ordered by travel certainty. Prefer cities you can reach for morning sessions without overnight travel. Consider smaller centres if metros fill quickly. Final allotment can differ from your choices because of operational constraints, so keep realistic alternatives.
Use the October 14–21 correction window for image, category, paper, or city changes. City allotment releases on January 4. Exams run on February 6, 7, 13, 14, 20 and 21, with results on March 19. Track PSU notifications and institute portals, including COAP and CCMT, once scores publish.
