# Tamil Nadu

> Tamil Nadu publishes a concrete ELCOT permanent-enrolment model: centres in collectorates, corporations, municipalities and other government offices, with the Aadhaar services they are designed to perform.

Canonical page: https://eaadhaarinfo.com/tamil-nadu

Important: eAadhaar Info is an independent reference publication. It is not UIDAI or a Government of India website. For transactions, current rules and final verification, use the official UIDAI or myAadhaar service linked by the article.

## Where ELCOT centres are placed

The state IT Department says ELCOT operates permanent enrolment centres across district collectorates, corporation headquarters and zones, municipalities, revenue and block offices, town panchayats and a PF office. Because the page also lists the service set, it is stronger evidence than a private map pin.

## The published service set

The centres are described as handling enrolment, mandatory biometric updates at ages five and fifteen, demographic update, Aadhaar search/print, lost EID and child enrolment. Residents should still check the current centre and fee because the page’s counts and pricing can lag operational changes.

## e-Sevai is nearby, but not identical

Tamil Nadu’s GIS dashboard maps e-Sevai centres. An e-Sevai location can help with state digital services, yet only an Aadhaar-enabled centre should accept a UIDAI enrolment or biometric transaction. Confirm the operator and insist on a UIDAI acknowledgement.

For a municipal centre, identify the exact office—not only the municipality name. Large corporations can have multiple zonal counters with different daily availability.
