Why Book an Appointment?

Bottom line: If an appointment slot is available, always book it.

Step-by-Step: Book Aadhaar Appointment Online

Step 1: Visit the Appointment Portal

Go to appointments.uidai.gov.in

Step 2: Select Your City

• Choose your State and City from the dropdown
• The portal shows available Aadhaar Seva Kendras and enrollment centres

Step 3: Choose a Centre

• Review the list of centres with addresses
• Select the most convenient centre near you

Step 4: Pick a Date and Time Slot

• Available dates are shown on a calendar (typically 1–5 days ahead)
• Time slots are usually in 30-minute windows (e.g., 10:00 AM, 10:30 AM)
• Grey/unavailable slots are already booked — choose a green/available slot

Step 5: Enter Your Details

• Enter your mobile number (required for OTP verification)
• You'll receive a 4-digit OTP via SMS
• Enter the OTP to verify

Step 6: Confirm and Save

• Review your booking details: centre, date, time
• Click Confirm
• Save or screenshot your appointment slip — it contains your booking reference number

Step 7: Visit the Centre

• Arrive 15 minutes before your slot time
• Show your appointment slip (printed or on phone) at the counter
• Carry all required documents (see below)

What to Carry to Your Appointment

For New Aadhaar Enrollment

• Proof of Identity: PAN card, passport, voter ID, driving licence
• Proof of Address: Passport, bank passbook, utility bill, voter ID, ration card
• Proof of Date of Birth: Birth certificate, SSLC marksheet, passport
• For children under 5: Parent's Aadhaar card + child's birth certificate

For Aadhaar Update

• Your Aadhaar number or Enrollment ID
• Supporting document for the field being updated
• For biometric update: just carry your Aadhaar number — no documents needed

General Tips

• Carry originals + one photocopy of each document
• Remove contact lenses before iris scan (if applicable)
• Ensure fingers are clean and dry for fingerprint capture

How to Check Slot Availability

Slots open on a rolling basis (usually 3–5 days in advance). Here's how to find available slots:

1. Visit appointments.uidai.gov.in
2. Select your city — the calendar shows availability
3. Morning slots (9:30–11:00 AM) fill up fastest — book early
4. Check back daily if no slots are available — new slots open each morning
5. Smaller cities and newer centres tend to have better availability

How to Reschedule or Cancel

• Currently, the UIDAI portal does not offer direct rescheduling
• If you miss your appointment, simply book a new one
• Missed appointments have no penalty — you can rebook immediately
• Walk-in is always available as a backup if you can't get an online slot

Fees

Appointment booking itself is always free. Never pay anyone for "booking help."

Important Tips

1. Book 2–3 days in advance — same-day slots are rarely available at busy centres
2. Early morning slots are best — less crowding and centres run on time
3. Keep your phone handy — you'll need OTP during booking and possibly at the centre
4. Don't rely only on appointment — if urgent, walk-in early morning at an Aadhaar Seva Kendra
5. Save booking reference — you may need it if there's a dispute about your slot

Frequently Asked Questions

Is Aadhaar appointment booking really free?

Yes, 100% free. UIDAI does not charge for appointment booking. If any website or agent asks for payment to book a slot, it is a scam.

Can I book an appointment for someone else?

Yes, you can book using anyone's mobile number. The person just needs to visit the centre at the scheduled time with their documents.

What if I miss my appointment?

Nothing happens — there's no penalty. You can either book a new appointment or visit the same centre as a walk-in.

How far in advance can I book?

Typically 3–5 days in advance. Slots open daily. If your preferred centre shows no availability, check back the next morning.

Do all Aadhaar centres accept online appointments?

No, online appointment booking is primarily available at Aadhaar Seva Kendras and select larger centres. Smaller or temporary centres may be walk-in only.

Can I book an appointment through the mAadhaar app?

The mAadhaar app currently does not support appointment booking. Use appointments.uidai.gov.in on any web browser. For other mAadhaar services, see our mAadhaar App guide.

What happens if the centre is closed on my appointment day?

In rare cases, centres may close unexpectedly. There's no automatic notification — check the UIDAI portal or call the centre before visiting. You can rebook for another date at no cost.
