Updating the identity or address documents linked to your Aadhaar costs nothing if you do it yourself on the myAadhaar portal before 14 June 2027. Do the same thing at a counter and you pay ₹75. That gap, set out in UIDAI’s current schedule of enrolment and update charges, is the most useful thing to know before you join a queue at an Aadhaar centre in Chennai.
Fees were revised from 1 October 2025, and a special free window for school-age children’s biometric updates ran until 30 September 2026. Below is what each kind of change costs now, what can be finished from home, and how to get a slot at UIDAI’s own Aadhaar Seva Kendra in Anna Nagar.
What an Aadhaar update costs now
UIDAI splits changes into three groups. Demographic details are your name, gender, date of birth, address, mobile number and email. Biometrics are fingerprints, iris scans and the photograph. Document updates mean refreshing the proof of identity and proof of address papers on your record, which UIDAI has been urging older cardholders to do. The current charges are:
| Service | Charge |
|---|---|
| New Aadhaar enrolment | Free |
| Demographic update on its own | ₹75 |
| Demographic update done along with a biometric update | Free |
| Biometric update (adults and other cases) | ₹125 |
| Mandatory biometric update at ages 5 to 7 and 15 to 17 | Free |
| Document update on myAadhaar | Free until 14 June 2027 |
| Document update at an Aadhaar centre | ₹75 |
One practical trick follows from that table. If you need a new photograph anyway, ask for your address or name change in the same visit. The demographic change then rides free on the ₹125 biometric update instead of costing ₹75 extra.
Children’s biometric updates
Children enrolled before the age of five give no fingerprints or iris scans, so UIDAI requires a first mandatory biometric update at five and a second at fifteen. Done between 5 and 7, or between 15 and 17, it is free. Outside those windows the normal charge is ₹125.
In October 2025 UIDAI waived the fee for children aged 7 to 15 for one year, which made the update effectively free for everyone between 5 and 17. UIDAI’s charge sheet gives 30 September 2026 as the end of that waiver. If your child is in that gap and missed the deadline, check the UIDAI site or ask at the centre whether the waiver has been extended before you pay. UIDAI also treats the mandatory child update as a stand-alone transaction, so plan a separate visit for any other change.
What you can do from home
The free online document update was first meant to end in June 2026. UIDAI issued an office memorandum on 13 May 2026 keeping it free from 15 June 2026 to 14 June 2027, Outlook Money reported. You log in on myAadhaar with an OTP sent to the mobile number already linked to your Aadhaar, upload scans of your current identity and address proof, and track the request online. The free waiver does not apply at centres.
UIDAI’s charge sheet also says email addresses can be updated free through the Aadhaar App until 31 December 2026. The same Outlook Money report says a new Aadhaar app will gradually replace mAadhaar, with QR-based sharing and tighter privacy controls, though no final rollout date had been announced.
Anything involving fingerprints, iris or a new photograph needs you in person. If your registered mobile number no longer works, you cannot receive the OTP for online services, so fixing the mobile number at a centre is usually the first job.
The Aadhaar Seva Kendra in Anna Nagar
UIDAI’s Aadhaar Seva Kendra list gives one centre for Chennai: TNUIFS Towers, 1st Floor (Left Wing), Block H1, 3rd Avenue, Anna Nagar East, Chennai 600102. Key points from UIDAI:
- Open all seven days, 9.30 am to 5.30 pm, with the last token issued at 5.30 pm.
- Appointments are booked free at bookappointment.uidai.gov.in, and you do not need an Aadhaar-linked mobile number to book.
- You can book for yourself or a family member, up to two appointments per person in a month.
- Walk-ins are served through a token system, so expect a wait at peak times.
- Services include enrolment, demographic and biometric updates, document updates and Aadhaar printouts.
UIDAI also authorises other enrolment and update centres across the city. The same charge schedule applies at all of them, so a centre asking for more than the listed fee is worth reporting to UIDAI.
Before you go
- Decide exactly which fields need changing, and combine changes into one visit where you can.
- Carry original identity and address documents that match the details you want on the card.
- For children, take the child along; biometrics cannot be captured otherwise.
- Keep the acknowledgement slip until the update shows on your downloaded Aadhaar.
