How to Book and Attend Your Aadhaar Enrollment or Update Appointment

Book your Aadhaar appointment online or at a nearby enrollment center

You can schedule an Aadhaar appointment through the official UIDAI (Unique Identification Authority of India) website at uidai.gov.in, or by visiting an enrollment center in person. The online route is faster — you choose your preferred date, time, and location, and receive a confirmation with your appointment number. If you go in person to an enrollment center, staff can book you on the spot, though you may wait for the next available slot.

The UIDAI website lets you search for enrollment centers by pincode or city. Once you find one near you, you can see which days and times have openings. You will need a mobile number to complete the booking — the system sends you an SMS confirmation with your appointment details. Write down your appointment number; you will need it when you arrive.

If the online system is slow or you do not have reliable internet, walking into an enrollment center works just as well. Staff there can check availability and book you immediately. Some centers are busier than others, so calling ahead to ask about wait times can save you a trip.

Key Takeaways

• Book online at uidai.gov.in by searching your area, selecting a date and time, and confirming with your mobile number, or visit an enrollment center in person to book on the spot.
• Bring your original identity document, address proof, and mobile number to your appointment — the documents you need depend on whether you are enrolling for the first time or updating an existing Aadhaar.
• Arrive 10 to 15 minutes early with all required documents; the enrollment process itself takes 10 to 20 minutes and includes biometric capture and a photograph.
• You will receive an acknowledgment slip at the end of your appointment with a reference number to track your Aadhaar status online.
• Processing time from appointment to receiving your Aadhaar number is typically two to four weeks, though it can vary by center and current volume.

What documents to bring for first-time enrollment

For a new Aadhaar enrollment, bring one original identity document and one original address proof. Identity documents include a passport, driver's license, voter ID, PAN card, or a state-issued ID. Address proof can be a utility bill, rental agreement, bank statement, or property tax receipt — it must show your name and current address and be dated within the last three months.

If you do not have both documents, some enrollment centers will accept alternatives. A school leaving certificate or birth certificate can work as identity proof in some cases. Ask the center staff before your appointment if you are unsure whether your documents will be accepted. Bring originals, not photocopies — staff will verify them and hand them back to you.

You will also need a mobile number that is active and in your name. The enrollment center will send you an OTP (one-time password) to that number during your appointment to verify it. If your phone number changes later, you can update it through the UIDAI website without another appointment.

What documents to bring for updating an existing Aadhaar

If you already have an Aadhaar and need to update your name, address, phone number, or other details, bring your Aadhaar number or the acknowledgment slip from your last enrollment. You will also need proof of the change you are making — for example, a marriage certificate if you changed your name, or a new address proof if you moved.

Some updates, like changing your phone number or correcting a spelling error, can be done online without an appointment. Check the UIDAI website to see which changes require an in-person visit. If you need an appointment, the booking process is the same as for new enrollment.

What happens during your appointment

When you arrive, check in at the enrollment center desk with your appointment number and documents. Staff will verify your identity and address documents, record your details into the system, and take a digital photograph of you. The photograph is taken against a plain background and becomes part of your Aadhaar record.

Next, you will provide your biometric data — your fingerprints from all ten fingers and an iris scan of both eyes. The process is quick and painless. The biometric scanner captures your data digitally; no ink or physical contact is involved. If you have very faint fingerprints or difficulty with the iris scan, staff can try multiple times or note the issue in your file.

Once biometrics are complete, you will receive an acknowledgment slip with a reference number, your name, and the date of enrollment. Keep this slip — you can use the reference number to check your Aadhaar status online. The entire process from check-in to acknowledgment usually takes 10 to 20 minutes.

How to track your Aadhaar after your appointment

Use your reference number from the acknowledgment slip to track your Aadhaar status on the UIDAI website. Go to uidai.gov.in, select "Check Aadhaar Status," and enter your reference number and mobile number. The system will show you whether your Aadhaar is being processed, has been generated, or is ready to download.

Processing time is typically two to four weeks from your appointment date, though it can take longer during peak periods or if the center is backlogged. You will receive an SMS to your registered mobile number when your Aadhaar is ready. You can then download it as a PDF from the UIDAI website, print it, or request a physical copy by mail.

If your status shows "rejected" or "on hold," the SMS will explain why — usually because a document was unclear or biometrics could not be captured clearly. In that case, you will need to schedule another appointment to resubmit or retake biometrics.

What to do if you miss or need to reschedule your appointment

If you cannot make your scheduled appointment, cancel it on the UIDAI website using your appointment number and mobile number. Canceling frees up the slot for someone else and lets you book a new date immediately. You can reschedule as many times as you need with no penalty.

If you miss your appointment without canceling, you will need to book a new one. There is no waiting period — you can schedule another appointment right away. However, if you miss multiple appointments, some centers may ask you to visit in person to rebook.

If you have an emergency and cannot reach the UIDAI website, go to the enrollment center in person and ask staff to reschedule you. They can do this at the desk.

Common issues and what to do about them

If your biometrics fail to capture — fingerprints too faint, iris scan unsuccessful — staff will try again. If it still does not work after several attempts, they will note this in your file and you may be asked to return for another appointment. Bring moisturizer or lotion to your appointment if you have very dry skin, as this can affect fingerprint capture.

If your documents are rejected because they are unclear, expired, or do not match your stated details, you will need to bring different documents to a new appointment. Ask the staff which documents would work instead before you leave.

If you do not receive an SMS when your Aadhaar is ready, check your status manually on the UIDAI website using your reference number. If the status still shows "processing" after six weeks, contact the enrollment center directly or visit in person to ask about the delay.

Frequently Asked Questions

Can I book an Aadhaar appointment for someone else?

No. The person getting the Aadhaar must book the appointment themselves or have a parent or legal guardian book it for them if they are a minor. Each person needs their own appointment with their own documents and biometric data.

What if I do not have a mobile number?

You will need a mobile number to complete your enrollment, as the UIDAI uses it to send you an OTP and later to notify you when your Aadhaar is ready. If you do not have one, you can get a prepaid SIM card from any mobile provider before your appointment. The number does not need to be on a long-term plan.

Do I need an appointment, or can I just walk in?

Most enrollment centers prefer appointments, but many will enroll you on a walk-in basis if they have capacity. However, you may wait longer. Booking an appointment online or in person guarantees you a time slot and is faster.

What if my address proof is older than three months?

Address proof must typically be dated within the last three months. If yours is older, get a new utility bill, bank statement, or other document with a recent date. Some centers may accept older documents in rare cases — call ahead to ask.

Can I update my Aadhaar online without an appointment?

Some updates, like changing your phone number, email, or correcting minor spelling errors, can be done online through the UIDAI website. Other changes, like updating your address or name, usually require an in-person appointment. Check the UIDAI website to see which updates are available online.
