How to Book Aadhaar Appointment Online: Step-by-Step Guide

August 23, 2026

The Unique Identification Authority of India (UIDAI) offers a robust online Appointment Management System (AMS) designed to streamline the process of visiting Aadhaar Seva Kendras (ASKs) and registrar-run centers. By utilizing this digital portal, Indian residents and Non-Resident Indians (NRIs) can schedule their visits in advance, effectively bypassing long physical queues and ensuring a smooth, organized experience. Whether you need to enrol for a new Aadhaar card, update your biometric details, or correct demographic information, learning how to book Aadhaar appointment online is the most efficient way to manage your Aadhaar-related tasks.

This comprehensive guide provides a step-by-step walkthrough of the online booking process, details the official fee structures implemented for the period from October 1, 2025, through September 30, 2028, and outlines the essential documentation and rules you must follow during your visit. By preparing in advance, you can ensure your appointment is completed quickly and without any unexpected complications.

Prerequisites and Eligibility for Online Aadhaar Booking

Before initiating the online booking process, it is important to understand the eligibility criteria and system requirements established by the UIDAI. The online appointment booking facility is open to all Indian residents as well as Non-Resident Indians (NRIs) who require Aadhaar services.

One of the most common misconceptions is that you must have an Aadhaar-registered mobile number to book an appointment online. In reality, you do not need a pre-registered mobile number to use the appointment portal. Any active mobile number capable of receiving a One-Time Password (OTP) can be used to log in and secure a slot. However, please note that if you wish to execute updates purely online via the myAadhaar portal without visiting a physical center, a registered mobile number remains mandatory.

To prevent misuse of the scheduling system, the UIDAI has implemented a strict booking frequency limit. A single resident can book a maximum of 4 appointments in a single calendar month using a single mobile number. This ensures fair access to available slots for all residents.

Additionally, there are specific guidelines regarding new adult enrolments. Per the UIDAI’s Office Memorandum dated September 21, 2022, certain commercial banks and registrars may restrict or have specific guidelines regarding new Aadhaar enrolments for individuals above 18 years of age. If you are an adult enrolling for the first time, it is advisable to check if your chosen registrar-run center has specific restrictions in place before booking.

Step-by-Step Guide to Book Aadhaar Appointment Online

The UIDAI portal allows you to book appointments at two distinct types of centers: UIDAI-run Aadhaar Seva Kendras (ASKs) and Registrar-run Aadhaar Seva Kendras. Depending on the location you choose, the booking process varies slightly. Below are the detailed, step-by-step instructions for both methods.

Method A: Booking at a UIDAI-run Aadhaar Seva Kendra (ASK)

UIDAI-run ASKs are state-of-the-art, dedicated centers managed directly by the authority. To book an appointment at one of these centers, follow these steps:

Navigate to the official UIDAI website or directly visit the appointment booking portal at https://bookappointment.uidai.gov.in.
Under the section labeled ‘Book an Appointment at UIDAI run Aadhaar Seva Kendra’, click on the dropdown menu and select your ‘City/Location’.
Click on the ‘Proceed to Book Appointment’ button.
You will be redirected to a new page. Select the tab appropriate for your specific service request: ‘Aadhaar Update’, ‘New Aadhaar’, or ‘Manage Appointments’.
Enter your active Mobile Number and the Captcha code shown on the screen, then click ‘Generate OTP’.
Enter the OTP received on your mobile phone and click ‘Verify OTP’ to authenticate your session.
Fill in the detailed Application Form. You will need to select your State, District, the specific Aadhaar Seva Kendra you wish to visit, your preferred language, and personal details such as your Aadhaar Number, Full Name, and the specific fields you wish to update.
Select your preferred Appointment Date and Time slot from the green-marked (available) slots displayed on the interactive calendar.
Carefully review all the entered details on the summary screen and click ‘Submit’.
An acknowledgement slip containing your appointment details, scheduled time, and a unique QR code will be generated. Print this slip or save it digitally on your mobile device to present when you arrive at the ASK.

Method B: Booking at a Registrar-run Aadhaar Seva Kendra

If there is no UIDAI-run ASK in your immediate vicinity, you can book an appointment at a Registrar-run Aadhaar Seva Kendra (often located in banks, post offices, or government offices) by following these steps:

Visit the official appointment portal at https://bookappointment.uidai.gov.in.
Look for the section designated for ‘Book an Appointment at Registrar run Aadhaar Seva Kendra’.
Click on the link to proceed to the registrar booking system.
Complete a one-time registration by entering your active mobile number and confirming the OTP sent to it.
Upon successful authentication, fill in your demographic and location details, select an available time slot at your preferred registrar center, and download your confirmation slip.

Managing Your Appointment: Rescheduling and Cancellation

Life can be unpredictable, and there may be times when you cannot attend your scheduled appointment. The UIDAI portal makes it easy to modify your booking without any penalty. If you need to change the date, time, or cancel the visit entirely, you can do so online.

To manage your booking, visit the official portal and navigate to the ‘Manage Appointments’ tab. After logging in with the mobile number used during the initial booking and verifying the OTP, you will see your active appointments. From this dashboard, you can easily reschedule the slot to a more convenient time or cancel it altogether. This flexibility ensures that residents can manage their schedules without losing access to services.

Official Aadhaar Service Fees and Charges (2025–2028)

The UIDAI has implemented a revised fee structure for Aadhaar services, which is effective from October 1, 2025, through September 30, 2028. It is crucial to familiarize yourself with these official rates to avoid overpayment. Below is the complete breakdown of the approved charges:

Biometric Update (Photo, Fingerprint, Iris) – First & second mandatory update (Ages 15 to 17 years): Free of cost.

Doorstep / Home Enrolment Services – Additional family members at the same address: Rs. 350 per person.

Required Documentation and Rules for Verification

When attending your appointment, you must adhere to strict documentation guidelines. The most important rule to remember is that no photocopies are accepted. Residents must carry original physical documents to the Aadhaar Seva Kendra. The operator will scan the original documents on the spot and return them to you immediately.

Depending on the service you require, you must present valid documents from the following categories:

Proof of Identity (PoI): A physical document containing your name and photo, such as a Passport, PAN Card, Voter ID, or Driving License.
Proof of Address (PoA): A physical document containing your name and current address, such as a Bank Statement, Utility Bills, or Passport.
Proof of Date of Birth (DoB): A valid Birth Certificate, Passport, or other officially recognized documents.

Importantly, there are exceptions to these documentation rules. No physical documents are required if you are visiting the center solely to update your mobile number, email ID, gender, or biometric records.

Important Rules, Limits, and Restrictions

To maintain the integrity of the national identity database, the UIDAI enforces strict limitations on demographic corrections and specific update procedures. You should keep the following lifetime limits in mind before booking an appointment for corrections:

Date of Birth Correction: Allowed only 1 time in a lifetime.
Name Correction: Allowed 2 times in a lifetime.
Gender Correction: Allowed 1 time in a lifetime.

Furthermore, Mandatory Biometric Updates (MBU) for children must be handled as standalone transactions. These mandatory updates cannot be clubbed with other demographic updates, and separate procedures must be followed to ensure the child’s records are updated correctly.

What to Expect at the Aadhaar Seva Kendra (ASK)

UIDAI-run Aadhaar Seva Kendras are designed to offer a hassle-free, comfortable environment for residents. These modern, state-of-the-art facilities feature air conditioning, comfortable waiting bays, wheelchair access for senior citizens and differently-abled individuals, and an automated Digital Token Management System.

ASKs operate seven days a week (except for national public holidays) from 9:30 AM to 5:30 PM. When you book your appointment online, you are granted direct entry to the center, allowing you to bypass the long physical token queues and access a dedicated fast-track desk.

While walk-ins are permitted at ASKs via a local physical token system, daily walk-in slots are strictly limited. Wait times for walk-in visitors are significantly higher than for those who have pre-booked their appointments online. Therefore, booking online is highly recommended.

Finally, be vigilant against unauthorized fees. You should never pay more than the official charges detailed in the fee section of this guide. If an operator or staff member demands extra money for any service, you can lodge a grievance on the spot with the Centre Manager or report the incident by calling the National Helpline at 1947.
