If your name is on the JoSAA 2026 Round 1 seat allotment list, congratulations — but the seat is not yours yet. Between allotment and confirmation sits a short, strict step called online reporting, where you accept the seat, pay the seat acceptance fee, and upload scanned copies of your documents for verification. Miss a deadline or upload a blurry, wrongly formatted file, and you can lose the seat you worked years for.
This guide walks through what happens after seat allotment, which documents you should keep ready, and — the part most students underestimate — how to turn a pile of paper marksheets and certificates into clean PDFs that the portal will actually accept.
What to do after your JoSAA seat is allotted
Once a round’s seat allocation is published on the official JoSAA portal, allotted candidates have to complete seat acceptance within the stated window. In practice this usually means three things, in order:
- Pay the seat acceptance fee online and keep the payment receipt.
- Choose your option for the next rounds (freeze, slide, or float) if you want to be considered for an upgrade.
- Upload your documents for online verification, then wait for the verifying officer to approve them or raise a query.
Exact dates, fees, and steps change every year and even between rounds, so treat your official allotment letter and the live JoSAA business rules as the single source of truth. This article explains the document and scanning side, which stays largely the same season to season.
Documents you are likely to need for online reporting
JoSAA publishes a document checklist, and it differs depending on whether your allotted institute is an IIT/IISc or an NIT+ institute (NITs, IIITs, GFTIs). Always confirm the current list for your category on the portal, but candidates are commonly asked to keep the following ready as scans:
- JEE (Main and/or Advanced) admit card and scorecard / rank letter
- Class X certificate / marksheet (often used for date of birth proof)
- Class XII marksheet and passing certificate
- Category certificate (SC/ST/OBC-NCL/EWS) in the prescribed central format, where applicable
- PwD certificate, if you are claiming that benefit
- A recent passport-size photograph and a valid photo ID
- The seat acceptance fee receipt generated after payment
Two practical notes. First, category and PwD certificates must usually be on the specific format JoSAA accepts — an old or state-format certificate can trigger a verification query, so check this early. Second, the public “suggested list” for NIT+ institutes can read slightly differently from the IIT/IISc list, so match yours to your allotted institute type rather than copying a friend in a different stream.
Before you upload: format, size and readability checks
Most JoSAA upload rejections are not about which document you sent — they are about how the file looks. The portal accepts documents within defined file types and size limits shown next to each upload field, and a verifying officer has to be able to read every line. Before you upload, make sure each file is:
- In the format the field asks for — usually PDF for certificates and an image for the photo/signature. Check the exact file type and maximum size displayed on the portal beside each field; do not assume last year’s numbers.
- Sharp and fully readable — no glare, no shadow across the text, no cut-off corners, and the whole page inside the frame.
- Correctly oriented — upright, not sideways or upside down.
- Complete — a two-sided certificate scanned as a single multi-page PDF, not one random side.
A photo of a document lying on your bed, taken at an angle with your shadow over it, is the classic cause of a rejected upload. That is exactly the problem a proper scanner solves.
How to scan JoSAA documents into clean PDFs on your phone
You do not need to find a cyber-cafe or a flatbed scanner. A phone scanner app captures the page, detects the document edges, straightens the perspective, removes shadows, and exports a crisp PDF — which is precisely what the portal wants. The workflow is simple:
- Lay the document flat on a plain, contrasting surface in even light (daylight near a window works well).
- Hold the phone parallel to the page and let the app auto-detect the borders.
- Review the captured page — check that every number and stamp is legible — and retake if anything is soft.
- Add more pages for multi-page certificates, then export as a single PDF.
- Confirm the file size and format match the portal field before uploading.
Using Scan Cam for marksheets, certificates and fee receipts
This is where a dedicated tool like Scan Cam, the document scanner for iOS and Android, makes the JoSAA upload stress-free. Scan Cam auto-detects document edges and corrects the angle, so a slightly tilted capture still comes out as a square, upright page. You can scan a Class XII marksheet and its reverse side into one multi-page PDF, scan the category certificate separately, and keep each file clearly named so you upload the right document to the right field.
Because allotment portals enforce size limits, the ability to export a clean, reasonably compressed PDF — without sacrificing the readability the verifying officer needs — matters more than people expect. Scanning everything once, in good light, and keeping the PDFs in one folder also means that if you slide or float into a better seat in a later round, your documents are already ready to re-upload in minutes.
Common JoSAA document-upload mistakes to avoid
- Uploading a phone photo instead of a scan — angled, shadowed images are the number-one reason for queries.
- Wrong format on the category certificate — it must match the central format JoSAA specifies.
- Cropping off a corner, seal, or signature — capture the entire page, edge to edge.
- Mismatched files — uploading the Class X marksheet into the Class XII field, or vice versa.
- Oversized or undersized files — ignoring the size limit shown beside the field.
- Leaving it to the last hour — scan and check everything a day before your reporting deadline so a re-scan never becomes a crisis.
JoSAA counselling rewards students who are calm and organised at exactly the moment everyone else is panicking. You cannot control the cut-offs, but you can control whether your documents are clean, complete, and ready. Scan once, scan well, and let a clear PDF do the talking when the verifying officer opens your file.
Always follow the official instructions and deadlines on the JoSAA portal and your allotment letter; document requirements and limits can change each season and may differ between IIT/IISc and NIT+ institutes.
