Incorrect document uploads are a top reason for the rejection of JEE Main 2026 application forms. Every year, thousands of students face issues with blurred photos, wrong file sizes, or mismatched certificates, which can lead to disqualification by the National Testing Agency (NTA).
This detailed guide is a complete checklist that explains every required document, file format, and size limit as per the official NTA Information Bulletin. By following these steps, you can ensure your photograph, signature, and certificates meet all verification standards and are uploaded successfully.
Before starting the JEE Main 2026 registration, every candidate must keep the required documents ready in the correct format, size, and clarity. Missing or incorrectly uploaded files are one of the most frequent causes of form rejection by the National Testing Agency (NTA). Here’s a quick and easy-to-scan master checklist of all documents needed for successful registration on the official website — jeemain.nta.ac.in.

| Passport-size Photograph | Identity & photo verification | Must be recent, clear, and in colour (preferably with name and date printed). Avoid selfies or group photos. |
| Candidate’s Signature | Confirmation of identity | Must match the signature done in exam attendance sheet. Use black or blue ink on white paper. |
| Parent/Guardian Signature | For declaration (if applicable) | Needed only if the candidate is a minor (under 18 years) at the time of registration. |

The photo and signature upload section of the JEE Main 2026 application form is where most candidates make mistakes. Incorrect photo dimensions, blurry images, or oversized files are among the top reasons for form rejection or Aadhaar authentication failure.To help you avoid these common errors, here’s a clear explanation of every rule and requirement specified by the National Testing Agency (NTA) for uploading your photograph and signature successfully.
Your passport-size photograph is used throughout the registration, admit card, and exam verification process, so it must follow NTA’s technical and quality standards.
| Requirement | Details |
| Photograph Type | Recent passport-size colour photograph (taken within the last 6 months). |
| Background | Plain white background with uniform lighting. |
| Key Feature | Candidate’s name and the date of photograph should be printed below the image (as per previous NTA guidelines). |

| File Format | JPEG / JPG |
| File Size | Between 10 KB – 200 KB |
| Recommended Dimensions | 3.5 cm × 4.5 cm |
The signature upload must also meet NTA’s prescribed format. Any mismatch between the uploaded signature and the one made during the exam may cause verification issues.

The certificate upload section in the JEE Main 2026 application form requires special attention.

Students applying under any reserved category must upload a valid Category Certificate issued by a competent authority. This document verifies eligibility for reservation benefits during JEE Main counselling and admission through JoSAA or CSAB.
| Requirement | Details |
| Issuing Authority | Must be issued by a competent authority — such as the District Magistrate, Sub-Divisional Officer (SDO), Tehsildar, or Revenue Officer. |
| Crucial Validity Date | For OBC-NCL and EWS categories, the certificate must be issued on or after April 1, 2026(tentative, as per NTA norms). Certificates issued before this date are not valid for JEE Main 2026. |
| File Format | |
| File Size | 50 KB – 300 KB |
| Mandatory Details | Candidate’s name, caste/category, validity period, issuing authority’s seal, and date of issue. |

Before final submission, double-check all uploaded certificates for clarity, date validity, and correct file format. Following NTA’s specifications ensures your category or PwD status is successfully verified, allowing you to claim the benefits during JEE Main 2026 counselling without any complications.

Uploading documents correctly is only the first step — the JEE Main 2026 document verification process continues even after registration. The National Testing Agency (NTA) cross-checks the details entered in the form with the original documents during various stages — at the exam centre, and later during JoSAA/CSAB counselling. Once you’ve successfully submitted your application, ensure that all uploaded information — name, date of birth, and ID proof details — matches your original certificates. Any mismatch between your uploaded and physical documents can lead to disqualification or withheld results. Important Reminder for Exam Day
The verification process continues after the result declaration during the Joint Seat Allocation (JoSAA) and Central Seat Allocation Board (CSAB) counselling rounds. At this stage, candidates must present all original documents for physical verification, including:
Keep all your original documents and their self-attested photocopies ready before the counselling process begins. This ensures smooth document verification and prevents delays in seat allotment. By following these verification rules carefully, you can avoid common errors, maintain eligibility, and ensure a seamless transition from registration to admission in your preferred engineering institute.
