Before we apply
Check your EB service number
Your subsidy application uses the service number on your EB bill. A wrong digit is a common reason for delay. Type your number below and we check its region, section and distribution codes against the TNEB list.
The check runs on this page. The number you type is not sent anywhere.
Spaces and dashes are ignored.
What next
The codes are on the TNEB list. This does not confirm the name on the account or that the connection is active, so we check the full record when we apply. The name on it should match your Aadhaar and bank account.
You can find the number on your EB bill as the service connection number, and on the TNEB SMS and payment receipt.
Find the right number
- Look at your latest EB bill. The service connection number is printed near the top.
- Check the TNEB SMS or the payment receipt from your last bill payment.
- Count the digits and compare each group with what you typed.
If you cannot find it, send a photo of your bill, a payment screenshot or the SMS to Nila on WhatsApp and we will read the number for you.
