👨💼 Do Tenants Need to Complete TANGEDCO Aadhaar Link?
Many Tamil Nadu residents are confused about tenants.
Here is the simplest explanation:
✔ Aadhaar linking is mandatory ONLY for the person whose name is on the EB connection.
If:
- The EB connection is in the owner’s name → OWNER must link Aadhaar
- The EB connection is in the tenant’s name → TENANT must link Aadhaar
- Tenant is living on rent → Tenant does NOT need to link Aadhaar
So, Aadhaar link is tied to connection ownership, not house occupancy.
⚠️ Important Things to Keep in Mind Before Linking Aadhaar
- Aadhaar must be linked to your mobile number for OTP
- Enter service connection number EXACTLY printed on bill
- Only Tamil Nadu residents are eligible for subsidy
- Aadhaar linking is NOT required for commercial connections
- Wrong details may cause rejection — check twice before submitting
