The term SIR refers to the Special Intensive Revision of electoral rolls — a focused nationwide drive conducted by the Election Commission of India to update the voter list. During this SIR period, citizens who were missed in previous revisions can add their name, correct details, update address, or request deletion of duplicates.

1. What Is the SIR (Enumeration) Form?

The SIR Enumeration Form — also known as the SIR Form or Enumeration Form (EF) — is a short online application used during the Special Intensive Revision to perform the following tasks:

✔ Add a new voter

(Equivalent to Form 6 during normal registration)

✔ Correct personal details

Name, age/date of birth, gender, spelling corrections

✔ Change / update address

Within the same AC or to another AC

✔ Remove duplicate or outdated entries

Where this option is available on the CEO portal

In most states, the SIR form is filled through the official voter services portal or the Chief Electoral Officer (CEO) website of your state.
You will need a valid mobile number (linked to voter ID or Aadhaar), and sometimes Aadhaar e-sign for online submission.

Before You Start — Checklist & Prerequisites

Requirement	Why It Is Needed
Mobile number linked to EPIC / Aadhaar	Required for OTP verification and identity authentication
Aadhaar card (for e-sign)	Used for Aadhaar-based OTP e-signature
Scanned passport-size photograph	Needed for identity verification in many states
ID proof / Address proof	Only if the portal requests — Aadhaar, Passport, DL, Utility Bill etc.
Active email (optional)	For confirmation & tracking

Important: Many state CEO offices clearly mention that the mobile number must be active and linked to your voter ID or Aadhaar.
If your mobile number isn’t linked, the portal may reject OTP verification or ask you to contact the BLO (Booth Level Officer).

Where to Fill the SIR Form Online

You should use only official government websites, such as:

✔ Election Commission of India – Voter Services Portal

(For new registration, correction, deletion, and SIR updates)

✔ State Chief Electoral Officer (CEO) Website

Most states publish a dedicated SIR 2025/2026 page with SOPs, eligibility rules, and online enumeration links.

⚠ Warning: Do NOT use unofficial “voter update” websites or social media links claiming fast approval.
Always check the domain ends with .gov.in or official CEO portals.

How to Fill the SIR Form Online

Step 1: Open the Official Portal

Click the Apply Online button on the ECI Voter Services Portal
or
Use your State CEO SIR Portal.
Both options lead to official enumeration services.

Step 2: Read Instructions / SOP Carefully

After the page opens, look for Special Intensive Revision (SIR) guidelines.
These instructions include:

• How OTP verification works
• Whether Aadhaar e-sign is mandatory
• File size limits for uploads
• State-specific verification rules

Step 3: Select the Type of Application

Choose the correct purpose:

• New Voter Registration
• Correction in Entries
• Change of Address
• Deletion of Duplicate/Shifted Entry

Selecting the wrong option may delay processing.

Step 4: Fill Your Personal Details

Enter your:

• Full Name
• Date of Birth or Age
• Gender
• Full Address with PIN
• Assembly Constituency (if known)
• Email (optional)

Tip: Make sure your name spelling matches Aadhaar or other IDs to avoid mismatch objections.

Step 5: Upload Required Documents

Upload scanned copies (as requested):

• Aadhaar / Passport / Driving Licence
• Utility Bill (if required for new address)
• Passport-size photograph (JPG/JPEG)

File size guidelines are usually mentioned on the upload page.

Step 6: Verify Using OTP / Aadhaar e-Sign

The portal will verify your identity using:

• OTP on mobile number linked to EPIC or Aadhaar, or
• Aadhaar e-sign (OTP to Aadhaar mobile number)

Complete the OTP immediately — delayed OTP often expires.

Step 7: Review the Form and Submit

Before submitting:

✔ Recheck name, DOB, address
✔ Ensure document uploads are clear
✔ Confirm mobile number is correct

Once you submit, you will receive an Acknowledgement / ARN Number.

Step 8: Save ARN for Tracking

After submission, the system generates:

• Application Reference Number (ARN)
• SMS/email confirmation (in many states)

Save this, as it helps you check status later.

5. After Submission: What Happens Next?

Once submitted, your form is forwarded digitally to the:

✔ Booth Level Officer (BLO)

Common Mistakes & How to Avoid Them

❌ Name mismatch

Use the same spelling as Aadhaar or official records.

❌ Incomplete address

Always include PIN, street name, and landmark.

❌ Wrong mobile number

OTP verification fails if your mobile isn’t linked.

❌ Large or incorrect file format

Compress files to meet size limits (JPG/PDF only).

❌ Choosing the wrong form type

Select the correct purpose to avoid processing delays.

Troubleshooting: If the Portal Is Down or You Can’t Submit

If the online SIR form is not opening or not accepting submission:

✔ Retry after some time — servers may be overloaded
✔ Try incognito mode or a different browser
✔ Clear cache/cookies
✔ Use a laptop instead of mobile (recommended)
✔ Contact your CEO office helpline
✔ Approach the BLO for manual assistance

Many states allow physical enumeration if online submission fails repeatedly.
