The term SIR stands for Special Intensive Revision of electoral rolls — a focused process conducted by the Election Commission of India to correct, update, and include eligible voters in the voter list. If your name was missed earlier or your voter details need correction, the SIR Enumeration Form allows you to update or add your details online, completely free of cost.
What is the SIR (Enumeration) Form?
The SIR Enumeration Form — also called EF, SIR Form, or Enumeration Form — is a short online application used during the Special Intensive Revision period to:
- Add a new voter (similar to Form 6 in normal registrations)
- Correct name, address, age, gender, or any personal details
- Update address within the same constituency
- Remove duplicate records (where applicable)
In simple terms, the SIR form helps ensure the voter list is accurate, updated, and error-free before elections.
- The ECI Voter Services Portal
- Your respective State CEO (Chief Electoral Officer) website
Each state may have slightly different labels or steps, but the entire process follows the same structure:
Fill details → Upload documents (if required) → Verify via OTP/Aadhaar → Submit → Receive ARN
Before You Start – Necessary Checklist

3. Where to Fill the SIR Form Online
You must use official government portals only:
(1) ECI Voter Services Portal (National Portal)
Contains services like new registration, corrections, and SIR-based updates.
(2) State CEO Website (State SIR Portal)
Most states publish a dedicated SIR page with SOPs and the online enumeration link.
4. How to Fill the SIR Form Online
Follow these steps carefully for a smooth application:
Step 1: Open the Official Portal
Use the Apply Online button or visit your State CEO website.
Look for:

Typical size limit: 50 KB–200 KB
Step 6: Complete OTP Verification / Aadhaar e-Sign

- OTP to mobile linked with EPIC/Aadhaar, or
- Aadhaar e-sign OTP
Enter the OTP immediately to avoid session expiry.
Step 7: Review and Submit the Form
- Check every detail
- Ensure address is accurate
- Verify documents are clear
Once submitted, the form becomes non-editable in most states.
Step 8: Save the Acknowledgment (ARN)
