Tamil Nadu Fill SIR Form Apply Now

India conducts elections on one of the largest scales in the world, and to ensure accuracy in the voter list, the Election Commission of India (ECI) organizes periodic revision drives. One such major initiative is the Special Intensive Revision (SIR). This process helps update the electoral rolls and ensures that every eligible citizen is correctly included in the voter list.

What is SIR? (Special Intensive Revision Explained)

SIR stands for Special Intensive Revision, a dedicated and time-bound process conducted every year or as required by the Election Commission of India. Unlike regular year-round voter services, SIR is a focused revision period where.

  • New names can be added to the electoral roll
  • Existing details can be corrected
  • Duplicates can be deleted
  • Address changes can be updated
  • Electoral rolls are verified and authenticated before elections

During this period, both online and offline enumeration activities take place. Booth Level Officers (BLOs) visit households, and the CEO/ECI portals open special online forms called Enumeration Forms (EF) or SIR Forms.

What is the SIR Enumeration Form?

The SIR Enumeration Form, also known as the EF Form, SIR Form, or simply Enumeration Form, is a simplified online application available only during the SIR period.

✔ Adding a New Voter

Like Form 6, used when a citizen turns 18 or has never registered.

✔ Correcting Details

Correcting errors in name, age, date of birth, gender, parent details, address, etc.

✔ Updating Address

If you have moved to:

  • A new house in the same constituency
  • A new constituency within the same state
  • Anywhere outside your previous electoral area

✔ Deleting Duplicate Records

Useful if your name appears twice or your old entry wasn’t removed after shifting.

✔ Ensuring Voter List Accuracy

The SIR form helps maintain accurate, error-free, updated electoral rolls.

In simple words, if you want any modification, new entry, or correction related to your voter ID during the SIR period, this is the form you must fill.
