Book Appointment Online with Aadhaar Card India 2026: UIDAI Portal, Hospital OPD & Government Service Booking

Two ways Aadhaar is used for appointment booking in India

When people search for "book an appointment online with Aadhaar card", they are typically looking for one of two things:

1. UIDAI appointment portal — to book a slot at an Aadhaar Seva Kendra for Aadhaar-related services (address update, biometric update, new enrolment, correction).
2. Hospital or government OPD registration — where Aadhaar number + OTP is used to verify patient identity and create a patient registration record (UHID) at government hospitals like AIIMS.

This guide covers both use cases.

UIDAI appointment portal — book an Aadhaar update appointment

The UIDAI (Unique Identification Authority of India) appointment portal allows you to book a slot at an Aadhaar Seva Kendra (ASK) for the following services:

• Update your address in Aadhaar
• Update your mobile number in Aadhaar
• Update your email address in Aadhaar
• Update biometric data (fingerprint, iris scan, photo)
• New Aadhaar enrolment for children above 5 years (biometric update)
• Correction of name, date of birth, or gender
• Download Aadhaar / reprint Aadhaar letter

Official UIDAI appointment portal: appointments.uidai.gov.in

How to login and book an appointment on the UIDAI portal

1. Visit: appointments.uidai.gov.in
2. Select your state and city — the portal shows available Aadhaar Seva Kendras in your location.
3. Select your preferred Aadhaar Seva Kendra — check the address to find the most convenient one.
4. Select the service you need — e.g., "Address Update", "Biometric Update", "New Enrolment".
5. Choose an available date and time slot — appointment slots are released on a rolling basis.
6. Enter your details: Aadhaar number (if existing), name, mobile number. An OTP is sent to your mobile for verification.
7. Confirm the appointment — you receive a booking confirmation with the appointment ID, date, time, and Aadhaar Seva Kendra address.
8. On the day: Arrive 15 minutes before your slot. Carry original Aadhaar (or acknowledgement slip for new enrolment), mobile phone for OTP, and any supporting documents for the update (e.g., address proof for address change).

Hospital OPD registration using Aadhaar card

Many government hospitals in India now require Aadhaar verification for new patient registration. This is not a legal mandate (Aadhaar is not compulsory for medical treatment) but a common practice at government hospitals for patient identification and UHID generation.

The Aadhaar-based hospital OPD registration process typically works as follows:

1. Visit the hospital's official OPD registration portal (linked from the hospital's official website).
2. Click "New Patient Registration" and enter your Aadhaar number (12 digits).
3. An OTP is sent to your Aadhaar-linked mobile number — enter it to verify your identity.
4. Your demographic details (name, date of birth, gender) are auto-populated from the Aadhaar database.
5. Complete the registration by selecting your department, preferred OPD date, and uploading previous records if applicable.
6. You receive a UHID (Unique Health Identification) number — this is your permanent patient ID at that hospital.

Important: If your mobile number is not linked to your Aadhaar, you may not receive the OTP. In this case, update your Aadhaar mobile number first at an Aadhaar Seva Kendra, or use an alternative identity proof (PAN card, Voter ID) as allowed by the specific hospital's policy.

AIIMS Jodhpur, Delhi, Mumbai — Aadhaar-based OPD booking

Other government services using Aadhaar-based appointment booking

Aadhaar is used for appointment verification across several government service portals in India:

• Passport Seva Portal — appointments.passportindia.gov.in — Aadhaar-based eKYC for passport applications
• DigiLocker — digilocker.gov.in — Aadhaar-linked digital document storage, mobile OTP login
• Pradhan Mantri Jan Arogya Yojana (PM-JAY / Ayushman Bharat) — beneficiary verification using Aadhaar at empanelled hospitals
• EPFO UAN Portal — Aadhaar-linked PF account management
• Income Tax e-Filing portal — Aadhaar-linked ITR filing and verification
• Jan Aushadhi centres — some states use Aadhaar for subsidised medicine access

Private clinic booking — Aadhaar vs mobile OTP

For private clinics, salons, and service businesses, Aadhaar-based verification is generally not required. Private service booking platforms — including SWIQ — use mobile OTP verification:

• Patient enters their name and mobile number at the time of booking
• An OTP is sent to the mobile number for verification
• No Aadhaar number is required for private clinic or salon appointments
• The mobile number serves as the unique identifier for the patient's booking history

This makes SWIQ-powered booking accessible to:

• Patients whose Aadhaar mobile number is not updated
• Children and dependents who do not have their own Aadhaar
• International patients visiting Indian clinics
• Senior citizens who find Aadhaar OTP processes complex

Find an Aadhaar Seva Kendra near you

If you need to update your Aadhaar (address, mobile, biometrics) before using Aadhaar-based hospital registration, find your nearest Aadhaar Seva Kendra:

1. Visit uidai.gov.in
2. Click "Get Aadhaar" or "Update Aadhaar" → "Locate Enrolment Centre"
3. Enter your PIN code or city name
4. A map and list of nearby Aadhaar Seva Kendras appears
5. Click "Book Appointment" next to your preferred centre
6. You are redirected to appointments.uidai.gov.in to complete the booking

UIDAI also operates walk-in services at some Aadhaar Seva Kendras — check availability at your nearest centre before booking an appointment.
