India’s first fully digital Census allows eligible households to complete their Census details online through the official Self-Enumeration portal before the door-to-door survey begins. If you are in Tamil Nadu, you can use this facility from 17 July to 31 July 2026.
This guide explains the complete Census Self-Enumeration process, including registration, login, filling the online form, downloading your Self-Enumeration ID (SE ID), and what happens during the Enumerator’s visit.
Before You Start
Before beginning the Census Self Enumeration process, keep the following information ready:
- A mobile number to receive the OTP
- Household address and location details
- Keep the basic details of every person residing in your household ready before starting the Self-Enumeration process.
- Basic housing details such as water supply, electricity, toilet, internet, cooking fuel, and vehicle ownership
- A stable internet connection
- To avoid duplicate records, each household should complete the process with only one mobile number.
Note: Based on the official Census guidance, you are generally not required to upload documents while completing the online self-enumeration.
How to Complete Census Self-Enumeration Online?
Step 1: Access the Official Census Self-Enumeration Portal
Begin the Self-Enumeration process by opening the official Census Self-Enumeration Portal in your preferred web browser. The portal is available only through the official government website. Do not use third-party websites or unverified links when accessing the Self-Enumeration portal.
Important: The Self-Enumeration portal is available daily from 6:00 AM to 12:00 Midnight.
Step 2: Choose Your State or Union Territory
Once the portal opens, select your State or Union Territory (State/UT) from the available options. After making your selection, the portal will display the Self-Enumeration schedule applicable to your region. Ensure you complete the process before the last date applicable to your State.
Step 3: Register and Verify Uisng Your Mobile Number and Access the Portal
Use one mobile number for one household, as instructed on the official portal.
If you are a new user, complete the registration process by entering your mobile number and verifying it using the OTP sent to your phone. If you have already registered, simply log in using your registered mobile number and the required credentials.
You may also need to complete the CAPTCHA verification before proceeding.
Step 4: Start Your Household Self-Enumeration
After logging in, begin the Self-Enumeration process by creating or selecting your household entry. Follow the on-screen instructions and verify your household details before proceeding to the questionnaire.
Step 5: Fill in the Household Information
Complete the online questionnaire by entering accurate information about your household. During the House Listing Operation (HLO), households are asked around 33 questions covering housing conditions and basic household amenities.
The information generally includes:
- House address and location
- Type of house and ownership status
- Number of household members
- Drinking water facility
- Toilet and sanitation facility
- Electricity connection
- Internet availability
- Cooking fuel used
- Vehicle ownership
- Other household amenities
Before moving to the next section, verify that all information entered is accurate.
Step 6: Review and Submit the Form
Review all the details carefully before submitting the form. If you notice any errors, correct them before final submission. Once you are satisfied that the information is complete and accurate, submit your Self-Enumeration form through the portal.
Step 7: Download or Save Your Self-Enumeration ID (SE ID)
After your form is successfully submitted, the portal generates a unique Self-Enumeration ID (SE ID). Save or download this ID and keep it in a safe place.
According to the official Census guidance, you should present your SE ID to the Census Enumerator during the door-to-door verification visit, if requested.
Do You Need the SE ID During the Enumerator’s Visit?
Yes.
According to the Press Information Bureau (PIB), Chennai, households that complete Census Self Enumeration online should present their SE ID when the Census Enumerator visits their home during the field enumeration in Tamil Nadu.
The Enumerator will use this ID to verify the information already submitted through the Self-Enumeration portal. Completing the online form does not replace the physical verification process. A house visit may still take place to confirm the submitted details.
What Happens If You Don’t Complete Self-Enumeration?
Self-Enumeration is provided as a convenient online option for eligible households. If you do not complete the online process, your household will still be covered during the regular door-to-door Census conducted by trained Census Enumerators.
In Tamil Nadu, Census officials will carry out the door-to-door House Listing survey from 1 August to 30 August 2026, during which enumerators will visit households to collect and verify the required information.
