UHID is the hospital identifier used to connect a patient with an existing hospital record. If a patient already has an AIIMS New Delhi UHID, that existing identity may be important for appointments, follow-up and continuity of records. It should not be confused with ABHA, and it should never be entered on an unofficial website.
When UHID matters
UHID is most relevant when:
- the patient has visited AIIMS New Delhi before;
- an earlier OPD card or hospital record exists;
- the patient is returning for follow-up;
- the official service asks an existing patient to use a UHID-based route;
- the patient wants to avoid creating an unnecessary duplicate hospital record.
A completely new patient without an existing UHID should begin with the new-appointment and registration explanation.
New patient without UHID
The ORS follow-up service distinguishes a patient with UHID from a patient who needs a new appointment. For a new patient, the current ORS FAQ says the appointment route can begin with a registered mobile number or ABHA.
The official service may generate or connect the hospital record as part of the later workflow. This independent guide cannot create, recover or validate a UHID.
Existing patient with UHID
An existing patient should preserve the earlier UHID and use the applicable follow-up or existing-patient route. Before starting:
- Keep the earlier UHID or OPD record available.
- Check whether the patient was given a specific follow-up instruction.
- Confirm the institution and department.
- Use the verified official service only when entering the UHID or other credentials.
- Save the resulting confirmation or acknowledgement.
Do not publish the UHID in a comment, contact form, social-media message or public support request.
Follow-up patients
The official ORS follow-up portal provides a separate login path for patients with UHID. This is why a follow-up patient should not automatically use a generic new-patient route.
The department's instruction can still be decisive. Some services may use a narrower follow-up, referral or physical process. This guide explains the general identity distinction; it does not override department-specific directions.
UHID and ABHA are different
UHID
UHID identifies the patient within the relevant hospital system and supports continuity with the earlier hospital record.
ABHA
ABHA is a national digital health identity. ORS describes it as supporting more accurate identification, reducing duplicate UHIDs and improving interoperability. Those are intended benefits, not a guarantee that every old record will always match automatically.
ABHA should not be presented as universally mandatory when the official ORS route also allows a registered mobile number for a new patient.
If you cannot use the existing UHID
- Recheck the number only on the official service; do not paste it into this website.
- Confirm that AIIMS New Delhi and the correct patient route were selected.
- Check the earlier OPD card or hospital document for the identifier as printed.
- Follow any recovery or support instruction shown by the official service.
- Use the relevant AIIMS contact category rather than an emergency number.
- Avoid creating another patient identity until the existing-record route has been checked.
This guide cannot look up a UHID or inspect the patient's hospital record.
Privacy rules
Never share the following with AIIMS OPD Guide:
- UHID
- ABHA number
- Aadhaar number
- OTP
- appointment or transaction ID
- report number
- medical documents
The Route Finder uses only non-sensitive choices and does not store them.
Official follow-up service
After deciding that the patient should use the existing/follow-up route, continue to the ORS Follow-up Patient Portal. It is an official Government of India service. Check the domain before entering the UHID or any credential.
Patients without UHID should first read the online appointment guide and then use the new-appointment route described there.
A practical decision table
| Your situation | What the identifier means for you | Best next step |
|---|---|---|
| Never visited AIIMS New Delhi | You may not have an AIIMS New Delhi UHID yet | Read the new-patient appointment flow and use the official new-appointment route |
| Visited before and have an OPD card | The printed UHID may connect the earlier hospital record | Keep the old card ready and use the existing-patient or follow-up path when applicable |
| Doctor wrote a return date or follow-up instruction | The visit is normally connected to the earlier episode of care | Follow the department instruction; do not start a fresh identity merely because it looks easier |
| Have ABHA but no known AIIMS UHID | ABHA and UHID serve different purposes | Use the route offered by the official service and allow it to create or link the hospital record where supported |
| UHID is rejected | The number, institution, patient details or route may not match | Recheck the printed record and the selected service before seeking official help |
Where patients usually find the UHID
Look first at documents issued during the earlier AIIMS visit: the OPD card, registration slip, appointment record or another hospital document. The label and layout may differ by document. Use the number exactly as printed. Do not rely on a number copied from an informal message when the original document is available.
If several family members use the same mobile number, match the UHID to the patient's own name and hospital document. A shared phone does not make the hospital identifiers interchangeable.
Avoid duplicate patient records
Creating a new-patient booking when an earlier record already exists can separate the new visit from older records. It may also make later follow-up more confusing. Before choosing “new patient,” check the old OPD documents and any written department instruction.
There are situations where the official system itself directs a person through a new workflow. Follow the current official prompt in that case, but do not invent a second identity simply to bypass a failed login. A failed lookup is a support problem, not proof that the old record has disappeared.
Before a return or follow-up visit
Keep the earlier OPD card, current appointment confirmation, clinician's follow-up note and requested reports together. Check the department, date, session and building independently. A valid UHID identifies the patient record; it does not by itself confirm that a particular clinic is running that day.
Questions patients commonly ask
Does a UHID guarantee an appointment?
No. It helps identify an existing hospital record. Slot availability, referral rules and department instructions still apply.
Can one UHID be used for every AIIMS institution?
Do not assume that an identifier from one institution will work identically at another. Confirm the hospital selected on the official service and use documents issued by that institution.
Can this website recover my UHID?
No. This site is an independent guide and deliberately does not collect patient identifiers. Recovery or correction must happen through an official AIIMS or ORS channel.
