Patients who want to consult a doctor at AIIMS New Delhi OPD can book an appointment online through the government’s Online Registration System (ORS). The online process allows a patient to select AIIMS New Delhi, choose an available department, check the appointment dates released for that OPD, enter patient details and receive an appointment confirmation.
For a new patient, ORS provides the online appointment and registration route. Patients who already have an AIIMS UHID should use the existing-patient/follow-up pathway instead of creating another new registration.
This guide focuses specifically on AIIMS Delhi OPD online appointment booking—from opening ORS to selecting the correct department, getting the appointment confirmation and handling common booking problems.
AIIMS Delhi Online Appointment: What You Need Before Booking
The AIIMS appointment process is easier if the required information is ready before opening ORS.
A new patient should generally keep the following available:
- An active mobile number
- Patient’s correct name
- Date of birth or age
- Gender
- Address details requested during registration
- ABHA number, if the patient wants to use it
- Information about the AIIMS department required for consultation
Patients who have visited AIIMS previously should also check old prescriptions, OPD cards or hospital documents for their UHID before starting a new-patient booking.
This is important because ORS provides a separate route for patients who already have a hospital UHID.
Official Portal for AIIMS Delhi OPD Appointment Booking
The online appointment system used for AIIMS New Delhi is:
ORS is a government platform used for online OPD appointments at participating government hospitals.
Because many hospitals use the same system, patients should verify that they have selected AIIMS, New Delhi rather than another AIIMS institution or another Delhi hospital.
For example, AIIMS Patna, AIIMS Raipur and other AIIMS institutions are separate hospitals. An appointment booked for another AIIMS does not become an AIIMS New Delhi appointment.
How to Book AIIMS Delhi OPD Appointment Online
The ORS booking journey can be understood as:
Verify patient → Select hospital → Select department → Choose appointment date → Enter/confirm patient details → Verify mobile → Receive confirmation
Here is the complete process.
Step 1: Open the ORS Patient Portal
Visit:
Choose the Book Appointment option.
The portal may display different healthcare services, so use the OPD appointment option rather than lab reports, blood availability or other services.
Step 2: Select Delhi
Choose Delhi as the state or location when the appointment system asks where the hospital is located.
This narrows the hospital list to institutions participating in ORS within Delhi.
Step 3: Select AIIMS, New Delhi
From the hospital options, select:
AIIMS, New Delhi
Check this carefully before continuing.
Patients searching for an AIIMS Delhi appointment sometimes encounter similarly named AIIMS institutions in other states. The hospital selected during this step determines where the appointment is actually booked.
Step 4: Select the Required OPD Department
ORS then allows the patient to select an available department or OPD.
This is one of the most important stages of the booking process.
The department should match the medical specialty the patient needs rather than simply whichever department has the earliest available appointment.
For example, a patient may be referred specifically to Orthopaedics, Dermatology, ENT, Medicine or another specialty.
If a doctor has already given a referral mentioning the specialty, use that information while selecting the department.
The departments visible online can depend on what AIIMS New Delhi has made available through ORS at that time.
Step 5: Check Available Doctors, Dates or Appointment Slots
After selecting the department, ORS displays the appointment choices available for that service.
Depending on the department and current booking configuration, the system may show available doctors, dates or appointment slots.
Select an appointment that suits the patient.
An important point is that ORS does not create unlimited appointments. The hospital determines the appointment quota and availability.
Therefore, if a particular date is unavailable, repeatedly refreshing the page does not guarantee that a slot will appear.
Step 6: Select New Patient When Booking for the First Time
If the person does not already have an applicable hospital UHID and is making a new registration, choose the New Patient option when prompted.
The portal then requests basic patient information.
Typical details include:
- Name
- Age or date of birth
- Gender
- Mobile number
- Address
- Other registration information required on screen
Enter these details exactly and consistently.
Incorrect spelling, using another person’s mobile details without care, or creating repeated registrations can make future identification of the patient’s record more difficult.
Step 7: Verify the Patient Using Mobile Number or ABHA
ORS supports patient verification using a mobile number and also integrates with ABHA.
An OTP may be sent to the registered mobile number during the process.
Enter the OTP requested by the portal to complete verification.
Patients using ABHA should use their own correctly linked health account.
ABHA is useful for patient identification across the digital-health ecosystem, but it should not be confused with the hospital’s own UHID.
Step 8: Review the AIIMS Appointment Details
Before confirming, check the important fields carefully:
| AIIMS Appointment Detail | What to Verify |
|---|---|
| Hospital | AIIMS, New Delhi |
| Patient | Correct patient’s name |
| Department | Required OPD/specialty |
| Appointment date | Date the patient can attend |
| Mobile number | Active and correctly entered |
| Patient type | New or existing patient as applicable |
A few seconds spent checking these details can prevent problems after the appointment has been generated.
Step 9: Complete the Appointment Booking
Complete the final confirmation shown by ORS.
Once the appointment is successfully created, the portal generates the appointment information and sends a confirmation SMS to the registered mobile number.
An attempted booking should not be treated as a confirmed appointment until the system has actually completed the process.
Step 10: Download or Save the AIIMS OPD Appointment Slip
After successful booking, an OPD appointment slip can be generated.
Download, print or otherwise safely retain the appointment information.
The slip contains information needed to identify the booking, such as the hospital, department, patient and appointment details.
Patients travelling from outside Delhi should especially confirm that the appointment has been generated before arranging their journey around the hospital visit.
AIIMS New Patient Online Appointment Process
A patient visiting AIIMS New Delhi for the first time normally uses the new-patient appointment process.
ORS states that a new patient needs a registered mobile number or ABHA for the online appointment route.
During new-patient registration, the patient provides the demographic information required by the system and completes mobile verification.
Once the appointment is confirmed, the booking becomes part of the patient’s hospital-registration journey.
A new patient should avoid creating multiple registrations simply because:
- an earlier appointment is unavailable;
- an OTP was delayed;
- a preferred department has no date;
- the first booking attempt was interrupted.
First determine whether the previous appointment actually failed before starting again.
Existing AIIMS Patient? Check Your UHID First
The process changes for someone who already has an AIIMS UHID.
ORS provides a separate Patient With UHID portal where an existing patient can log in for appointment and health-record services.
The system asks the patient to select the state and hospital and provide the UHID or relevant search criteria.
Therefore, a returning AIIMS patient should first check previous documents for:
UHID / hospital registration information
rather than automatically choosing New Patient again.
This helps maintain the patient’s hospital record rather than unnecessarily starting a separate registration.
What Is AIIMS UHID?
A UHID is the Unique Hospital Identification associated with a patient’s hospital record.
It helps AIIMS and the hospital information system identify an existing patient across visits.
A UHID may appear on previous:
- OPD cards
- registration documents
- prescriptions
- appointment records
- hospital-generated patient documents
For follow-up care, retaining the UHID is particularly useful because the next appointment may need to be connected with the existing record.
ABHA vs UHID in AIIMS Appointment Booking
Patients often see both terms while using digital hospital services, but they are not the same thing.
| Identification | Main Purpose |
|---|---|
| ABHA | Digital health identity used across India’s ABDM healthcare ecosystem |
| UHID | Hospital patient identifier associated with the existing hospital record |
An ABHA number is a 14-digit health identifier.
Using ABHA can help with accurate patient identification and can reduce duplicate health records across connected healthcare systems.
A UHID, however, is particularly relevant when an existing AIIMS patient wants the hospital system to recognize the previous record.
Can You Book AIIMS Delhi Appointment Without ABHA?
A patient should follow the identification choices presently offered by ORS.
The current ORS guidance identifies a registered mobile number or ABHA as the prerequisites for a new-patient appointment.
This means patients should not assume that creating a new ABHA is always the only possible starting point before opening the appointment system.
Use the patient-verification method presented during the actual ORS booking process.
How AIIMS Appointment Slot Availability Works
A very important part of online booking is understanding what an available slot actually represents.
The number of appointments available online is not decided by the patient’s search or by ORS independently.
The respective hospital determines its appointment quota, and those available appointments are incorporated into the system.
This means:
- One department may have appointments when another does not.
- A preferred date may not be offered.
- Online availability can differ by OPD.
- Seeing the department does not guarantee an immediate date.
- A slot that is not offered cannot simply be manually selected.
This is why patients should base travel plans on a confirmed AIIMS appointment, not merely on the expectation that a date will become available.
What If No AIIMS Delhi Appointment Slot Is Available?
If the required AIIMS department does not show an appointment, first make sure the booking has been configured correctly.
Check the Hospital
Confirm that AIIMS, New Delhi is selected.
Check the Department
A similar specialty name or wrong OPD selection can take the patient to an unrelated appointment calendar.
Check Patient Type
An existing patient may need the UHID/follow-up route rather than another new-patient appointment.
Check the Available Dates Again
If dates are shown, select only an actual available appointment.
If no suitable slot is available, the patient’s desired date cannot be forced through the ORS interface.
Consider the Physical New-Appointment Route
AIIMS New Delhi also provides a physical new-appointment route at the New Raj Kumari Amrit Kaur OPD.
AIIMS information lists the physical new-appointment period as 8:00 AM to 10:00 AM.
However, on-site registration should not be interpreted as a guarantee of access to every specialist or department on any chosen day. Departmental arrangements and patient capacity still matter.
Can Someone Else Book the AIIMS Appointment for the Patient?
ORS allows the online appointment process to be completed over the internet, and its guidance also recognizes that a patient or attendant may obtain an OPD appointment.
The patient details entered in the actual registration should still belong to the person who will receive treatment.
Do not enter the attendant’s identity as though the attendant is the patient simply because that person is operating the phone or computer.
An active mobile number accessible during OTP verification is also important.
Can You Choose a Specific Doctor at AIIMS Delhi Online?
The options available to the patient depend on what the selected AIIMS department makes available through ORS.
The system may display department, doctor or appointment-slot choices depending on the configuration of that OPD.
Therefore, patients should not assume that every AIIMS consultant can be independently selected online.
If a previous AIIMS prescription specifically advises follow-up with a particular unit, clinic or doctor, an existing patient should follow the instructions connected with that previous visit rather than creating an unrelated new appointment solely to select a name.
AIIMS Appointment Confirmation SMS
After the appointment process is completed, ORS sends confirmation through SMS.
This confirmation is important because it indicates that the appointment has progressed beyond simply selecting a hospital and department.
Keep the registered mobile accessible after booking.
If the patient is travelling from another city, verify the appointment information before finalizing travel arrangements.
What to Check on the AIIMS Appointment Slip
After downloading the OPD appointment slip, check it before closing the portal.
The most important information is:
- patient’s name
- AIIMS New Delhi as the hospital
- selected department
- appointment date
- appointment/reference information
- any instructions displayed for the visit
If the patient is an existing AIIMS patient, also keep previous UHID-related documents available.
Do not edit or manually alter an appointment slip if something is incorrect. Use the relevant appointment system to resolve the booking issue instead.
What to Carry for the AIIMS OPD Visit
For an appointment already booked online, keep the information directly related to the consultation together.
Useful items can include:
- AIIMS OPD appointment confirmation
- downloaded or printed appointment slip
- identification used during registration
- previous AIIMS OPD card or UHID, if applicable
- earlier prescriptions
- referral document, if applicable
- relevant test reports and imaging
- records related to the condition for which consultation is being sought
The documents required for a new patient may differ from those needed by a returning patient, so follow any instructions shown on the generated appointment information.
AIIMS Delhi Appointment Booking by Telephone
Patients who cannot comfortably complete the online process can also find hospital contact options outside ORS.
For appointment or slot-related issues, the ORS hospital contact listing for AIIMS New Delhi gives the hospital board number:
011-26588500
The same ORS listing also provides a separate number for follow-up appointment assistance: 9115444155.
AIIMS New Delhi’s general board numbers are:
011-26588500
011-26588700
A telephone enquiry should not be treated as a way to bypass appointment availability. If a department has no available booking quota, calling does not automatically create an additional appointment.
Online Booking vs AIIMS Hospital Registration Counter
Patients can obtain appointments through the online system or use applicable hospital registration facilities.
| Booking Method | Useful For |
|---|---|
| ORS online appointment | Booking an available appointment before reaching AIIMS |
| UHID patient portal | Existing patients accessing appointment/record services |
| Hospital registration counter | Patients using the applicable physical registration route |
One advantage of online appointment booking is that patients can complete part of the appointment process before reaching the hospital instead of relying entirely on an appointment-cum-registration counter.
For patients travelling a long distance, this difference can be particularly useful.
Common AIIMS Online Appointment Booking Problems
OTP Is Not Arriving
Check whether the mobile number was entered correctly and whether the phone can currently receive SMS.
Avoid repeatedly creating new patient registrations merely because an OTP was delayed.
Wrong AIIMS Hospital Was Selected
Return to hospital selection and make sure the appointment is for AIIMS, New Delhi.
An appointment at another AIIMS institution is separate.
Wrong Department Was Selected
Do not complete an unrelated appointment simply because it has an earlier available date.
Return and choose the department appropriate for the patient’s consultation or referral.
No Appointment Date Is Available
The selected department may not presently have an appointment quota available for the dates being checked.
The patient can check available options again or use another appropriate appointment route.
Existing Patient Accidentally Chose New Patient
Check previous AIIMS documents for the UHID and use the existing-patient pathway where applicable.
Appointment Was Booked but Slip Was Not Saved
Use the appointment services associated with the patient’s booking information to retrieve the relevant appointment details rather than attempting to recreate the appointment immediately.
Important Difference: Appointment Booking Is Not Emergency Registration
The AIIMS OPD online appointment system is for planned outpatient consultation.
It is not the process for obtaining immediate treatment in a medical emergency.
A patient requiring urgent emergency assessment should use the appropriate emergency service rather than waiting for a future OPD appointment slot.
AIIMS Delhi Online Appointment Checklist
Before considering the booking complete, confirm all of these:
- Correct hospital: AIIMS, New Delhi
- Correct patient
- Correct patient type
- Correct OPD department
- Appropriate appointment date
- Mobile verification completed
- Appointment successfully confirmed
- Confirmation SMS received or appointment information generated
- OPD slip saved
- Previous UHID available if the patient has visited AIIMS earlier
For patients coming from outside Delhi, it is especially useful to finish this check before booking travel around the OPD visit.

Which is the official portal for AIIMS Delhi online appointments?
Online OPD appointments for AIIMS New Delhi are available through the government’s Online Registration System (ORS) at ors.gov.in.
Is a mobile number required for AIIMS online appointment booking?
ORS uses mobile verification in the appointment process. A new patient should keep an active mobile number available while booking.
Do I need ABHA to book an AIIMS New Delhi appointment?

Can an old AIIMS patient book through ORS?
Yes, but a patient who already has a hospital UHID should check the dedicated UHID patient portal/follow-up pathway rather than unnecessarily registering as a completely new patient.
What is the difference between a new patient and a follow-up patient at AIIMS?
A new patient begins a new appointment/registration journey. A follow-up patient already has an AIIMS hospital record, usually identified through a UHID, and should use the relevant existing-patient process.
Why is AIIMS Delhi not showing an appointment date?
The selected OPD may not currently have a bookable quota for the dates being checked. Appointment availability is controlled by the hospital and department.
Can I get an AIIMS appointment by calling if ORS shows no slot?
Calling can help with appointment-related enquiries, but it should not be assumed to create a new appointment when the relevant department has no available booking capacity.
Can my family member book an AIIMS appointment for me?
An attendant can assist with online appointment booking, but the registration should contain the patient’s correct information.
Can I book AIIMS Delhi appointment without visiting the hospital first?
For OPDs available through ORS, a new patient can complete the online appointment process before travelling to AIIMS New Delhi.
Does an online AIIMS appointment guarantee consultation with a particular doctor?
The available department, doctor and slot options depend on what AIIMS makes available through the booking system. A general OPD appointment should not automatically be interpreted as a guaranteed consultation with a specific consultant.
What should I do after booking an AIIMS appointment online?
Save the confirmation and appointment slip, verify the department and date, keep relevant identification and previous medical records ready, and follow any visit instructions included with the appointment.
Final Takeaway
For a new AIIMS Delhi OPD appointment, the safest online route is to start with the government ORS portal, select AIIMS, New Delhi, choose the correct department and an actually available appointment date, complete patient verification and retain the final appointment confirmation.
For someone who has already been treated at AIIMS, the first step should instead be checking previous records for the UHID and using the existing-patient pathway where applicable.
The key is not simply getting any available booking. A useful AIIMS appointment is one that has the correct patient, correct hospital, correct department and confirmed appointment date.
