The TNEB Service Number is a unique 12-digit identifier assigned to every electricity consumer in Tamil Nadu. The format (04-454-006-2222) is structured as follows:

• First 2 digits (04): Represents the circle code
• Next 3 digits (454): Indicates the distribution section code
• Next 3 digits (006): Represents the subdivision code
• Last 4 digits (2222): Unique consumer number within the subdivision

This format helps TNEB efficiently manage and identify consumers across different regions.

You can find your distribution code using these methods:

1. Check your electricity bill: The service number is printed on every TNEB bill
2. Use our region list: Browse through the region tabs above to locate your area and find the corresponding section code
3. Contact TNEB customer service: Call the TNEB helpline at 1912 or visit your nearest TNEB office
