Quick answer: Book an Aadhaar Seva Kendra appointment at appointments.uidai.gov.in, choose your city, pick a slot, and carry the original documents plus the appointment slip. A mobile number update costs ₹75, biometric update ₹125, and demographic updates ₹75. Slots at busy centres fill days ahead, so book early morning slots and check the portal for available appointments. Walk-in availability and queues vary by centre.
When you need to visit in person
| What you need to change | Online possible? | Centre visit needed? |
|---|---|---|
| Address | Yes, on myAadhaar with proof | No |
| Mobile number | No | Yes |
| No | Yes | |
| Name (major correction) | Limited | Usually yes |
| Date of birth | No | Yes, with proof |
| Gender | No | Yes |
| Biometrics (fingerprint, iris, photo) | No | Yes |
| Child biometric update at 5 and 15 | No | Yes, and it is free |
| New enrolment | No | Yes |
The mobile number update is the one that catches most people out, because without a working registered mobile you cannot download e-Aadhaar, use DigiLocker properly, or complete most OTP-based verifications. See our guide on what to do when you have lost the registered mobile.
How to book the appointment
- Go to appointments.uidai.gov.in and choose Book an Appointment.
- Select your city or location. Note that the site distinguishes between UIDAI-run Aadhaar Seva Kendras and bank or post office enrolment centres, which have different slot availability.
- Choose the service: new enrolment, or the specific update you need.
- Enter your mobile number and verify the OTP.
- Fill in your Aadhaar number and the details you want changed.
- Pick a date and time slot, then pay online if the service carries a fee.
- Download and save the appointment slip with its acknowledgement number.
Fees
| Service | Fee |

Fees are set by UIDAI and are the same at every authorised centre. Anyone asking for more is overcharging; the rate card is displayed at the centre and you can complain on the spot.
Documents to carry
- Original Aadhaar card or a printout of e-Aadhaar for any update.
- Proof of identity: passport, PAN, voter ID, driving licence or ration card.
- Proof of address for an address change: electricity or water bill, bank passbook, rent agreement, passport, or a signed certificate from a listed authority. It must be recent, usually within three months for utility bills.
- Proof of date of birth for a DOB change: birth certificate, passport, school leaving certificate, or PAN.
- The appointment slip, printed or on your phone.
- For a child: the parent’s Aadhaar and the child’s birth certificate.
Carry originals; centres verify and return them. Photocopies alone are not accepted for verification.
Getting a slot at a busy centre
- Check late at night. Cancelled slots are released back into the pool and are easiest to catch when few people are looking.
- Look at nearby cities or suburbs. Centres a short distance out often have same-week availability while the central one is booked for a fortnight.
- Try bank and post office enrolment centres, not just UIDAI Seva Kendras. Many banks and post offices run Aadhaar services with much shorter queues.
- Book the first slot of the day. Delays accumulate through the day, so a 9:30am appointment usually runs on time while a 4pm one may not.
- Walk-ins are accepted at many centres on a token basis, but expect a long wait, and some centres stop issuing tokens by mid-morning.
After the visit
You receive an acknowledgement slip with a 14-digit Update Request Number (URN). Track the status at myaadhaar.uidai.gov.in under Check Update Status. Most updates complete within a few days to a couple of weeks. Track the mobile update; OTP services use the new number after the update is approved.
If an update is rejected, the reason is shown against the URN. The usual causes are a document that does not match the name on record, or an unclear scan. You can resubmit, and there is no limit on attempts, though the fee applies each time.
Frequently asked questions
Can I update my mobile number online?
Check the current Aadhaar app options and eligibility. If you cannot complete the required verification, use an authorised Aadhaar centre.
How many times can I change my name?
UIDAI applies limits on name, date of birth and gender changes over the lifetime of the Aadhaar number. Address changes have no such limit.
Do I need to update Aadhaar every 10 years?
UIDAI encourages document updates for Aadhaar numbers issued more than 10 years ago. It is a document refresh rather than a re-enrolment, and can often be done online through myAadhaar.
Is there a helpline?
Yes, UIDAI operates a toll-free helpline on 1947, available in multiple languages.
