Quick answer: No central rule makes it compulsory to link Aadhaar with a caste certificate. Caste certificates are issued by state government authorities under each state’s own procedure, and Aadhaar usually comes in only as one proof of identity or address when you apply, often through a state e-District portal or a Common Service Centre. A 2016 central initiative asked states to issue caste and residence certificates to schoolchildren and to try to issue them along with the Aadhaar number “if feasible”; it did not create a nationwide Aadhaar mandate.
What a caste certificate is and who issues it
A caste certificate is official proof that a person belongs to a particular Scheduled Caste (SC), Scheduled Tribe (ST) or Other Backward Class (OBC). It is needed to claim reservation in education and government jobs, fee concessions and many scholarships.
According to the Department of Personnel and Training (DoPT), caste certificates are issued by authorities authorised by the state government, and each state or Union Territory lays down its own procedure. For central government purposes, DoPT accepts certificates in the prescribed format issued by officials such as:
- a District Magistrate, Additional District Magistrate, Collector, Deputy Commissioner, Sub-Divisional Magistrate, Taluka Magistrate or Executive Magistrate;
- a Chief Presidency Magistrate or Presidency Magistrate;
- a Revenue Officer not below the rank of Tehsildar;
- the Sub-Divisional Officer of the area where the applicant or their family normally lives.
Because certificates are state-issued, the documents required, the fee (if any), the time taken and the format vary from state to state.
Is Aadhaar linking compulsory for a caste certificate?
An earlier version of this article said the Government of India had made it mandatory to link Aadhaar with caste certificates, and that UIDAI had asked all students to link their Aadhaar. We could not find any such mandate, and UIDAI does not issue or link caste certificates. Here is what actually happened.
The 2016 school-level certificate initiative
In 2016, DoPT issued guidance, reported by the Press Trust of India in May 2016, asking states and Union Territories to issue certificates to students at school as an annual exercise. According to DoPT’s FAQ on the initiative:
- SC and ST students would get a caste or tribe certificate and a domicile certificate, and other students a residence certificate.
- States could choose to do this in Class V or Class VIII. The original article said Class 5 or 7, which was a mistake.
- The school headmaster or principal would collect the documents and submit them to the state’s revenue authorities.
- Authorities would issue the certificates “preferably within a period of 30–60 days”.
- On Aadhaar, the FAQ said states “may link it to Aadhaar enabled data, if feasible” and should make “sincere efforts” to issue the certificates along with the Aadhaar number.
The stated aim was to reduce delays and harassment faced by SC and ST students and to speed up scholarships. The wording on Aadhaar was a recommendation to states, not a legal requirement for students, and how far each state acted on it varies.
The legal position on Aadhaar
Under the Aadhaar Act, as read by the Supreme Court in 2018 and amended in 2019, Aadhaar can be made compulsory only for government subsidies, benefits and services under Section 7 of the Act, and for PAN and income tax. Even under Section 7, the person must be offered another way to prove identity if they do not have Aadhaar or authentication fails, and a child cannot be denied a benefit for lack of Aadhaar.
How Aadhaar is used when you apply for a caste certificate
Many states now accept caste certificate applications online through their e-District or citizen service portals, or at Common Service Centres. Aadhaar commonly appears in these ways:
- Proof of identity or address: many states list Aadhaar among the accepted documents, alongside alternatives such as a voter ID, ration card or school record.
- Portal login: some state portals let you register or sign in with Aadhaar OTP.
- Digital certificates: some states make certificates available in DigiLocker, the government’s document wallet. DoPT’s 2016 FAQ also mentioned uploading certificates to e-locker facilities where available.
The proof of caste itself usually comes from other records, such as a parent’s caste certificate, school records showing caste, revenue records or a local inquiry, depending on the state. Check your state’s portal for its exact list before you apply.
If your name or address on Aadhaar does not match your other documents, correct it before using Aadhaar as proof. Address and supporting documents can be updated online on myAadhaar; name and date of birth need an Aadhaar centre. See our guides to updating your Aadhaar address and filling the Aadhaar correction form.
Where Aadhaar and a caste certificate are both needed: scholarships
Scholarships are where Aadhaar and caste certificates most often meet. The National Scholarship Portal (scholarships.gov.in) uses a One Time Registration (OTR) number issued on the basis of the student’s Aadhaar number or Aadhaar Enrolment ID, with face authentication in the NSP OTR app. Scholarship money is paid by Direct Benefit Transfer, and the portal guides students on seeding Aadhaar with their bank account through NPCI’s Bharat Aadhaar Seeding Enabler (BASE). Each scheme then asks for a valid caste certificate and income proof as per its own rules.
The original article said scholarships needed a family income within ₹1 lakh a year. Income ceilings differ from scheme to scheme and are revised from time to time, so check the specific scheme’s guidelines on the portal rather than relying on a single figure. For the wider picture of what Aadhaar must and need not be linked with, see our overview of Aadhaar linking.
Reservation: correcting the old figures
The original article contained several reservation figures that were wrong:
- “49% reservation for SC and ST”: in central government jobs and central educational institutions, reservation is 15% for SC, 7.5% for ST and 27% for OBC, with a further 10% for the Economically Weaker Sections (EWS) category. SC and ST together account for 22.5%, not 49%. States set their own percentages for state jobs and institutions.
- “It doesn’t matter what your cut-off mark is”: reserved candidates still have to meet the qualifying standards and cut-offs set for their category in each exam or admission process.
- “63% of seats reserved in both Lok Sabha and Rajya Sabha”: this was incorrect. Seats are reserved for SC and ST in the Lok Sabha and state assemblies under the Constitution, but there is no caste-based reservation in the Rajya Sabha.
- Women’s reservation: the Constitution (One Hundred and Sixth Amendment) Act, 2023 reserves one-third of seats in the Lok Sabha and state assemblies for women, including within SC and ST seats. It takes effect only after delimitation based on the first census after the Act, so it is not yet in force.
- Exam fees: many recruitment exams waive or reduce application fees for SC and ST candidates, but the rule differs by exam, and it does not mean marks are ignored. Check each notification.
Frequently asked questions
Do I need Aadhaar to apply for a caste certificate?
It depends on your state. Many states accept Aadhaar as one proof of identity or address and also accept alternatives. No central law requires Aadhaar for a caste certificate. Check your state’s e-District portal for its document list.
Can I link my existing caste certificate with Aadhaar online?
There is no UIDAI service to link a caste certificate with Aadhaar. Some states record the Aadhaar number in their certificate database or make certificates available in DigiLocker, but that is a state system, not a UIDAI one.
Is a caste certificate from one state valid in another?
For central government jobs and institutions, a certificate issued by a competent authority in the prescribed central format is accepted. State-level benefits usually depend on the state’s own caste lists and domicile rules, so a certificate from another state may not qualify for them.
Who helps schoolchildren get caste certificates?
Under the 2016 DoPT guidance, school heads were to collect documents from students in the chosen class and send them to the revenue authorities. Whether your state still runs this school-level drive varies, so ask your school or district office.
This guide was checked in October 2026 against the Department of Personnel and Training’s FAQ on residence and caste certificates, the Aadhaar Act as amended in 2019, the National Scholarship Portal and PRS Legislative Research’s summary of the 2023 women’s reservation amendment. Caste certificate rules are set by each state, so confirm requirements on your state’s official portal before you apply.
