Aadhaar: where it is required and where it is not
What the Supreme Court decided on Aadhaar, where the law can require it, where it cannot be forced on you, and how to protect your number from misuse.
In short
- The government can require Aadhaar for subsidies, benefits and services paid from the Consolidated Fund of India, such as ration, pensions and scholarships, but must offer another way to prove identity if you do not have it or authentication fails Sec 7 Aadhaar Act.
- Aadhaar cannot be made compulsory for a bank account, a SIM card or school admission (K.S. Puttaswamy v. Union of India, 2018). Banks and telecom companies may accept it only if you choose to give it.
- Aadhaar is proof of identity, not of citizenship Sec 9 Aadhaar Act, and not conclusive proof of date of birth.
- Protect it: use a masked Aadhaar, lock your biometrics, never share an OTP. For fraud call 1930; for Aadhaar problems call UIDAI on 1947.
School admission, bank accounts, SIM cards, hospital visits, rations: at some point almost everyone in India has been told, "Aadhaar dena padega." Sometimes this is true. Sometimes it is not, and people are turned away from things they are entitled to. Knowing where Aadhaar is legally required, and where it is only optional, lets you get what is yours without giving away more than you must.
What the Supreme Court decided
In K.S. Puttaswamy v. Union of India (2018), a five-judge bench upheld the Aadhaar Act with important limits, applying the privacy test from its 2017 judgment:
- The government can require Aadhaar for subsidies, benefits and services funded from the Consolidated Fund of India Sec 7 Aadhaar Act.
- Linking Aadhaar with PAN for income tax is valid.
- Aadhaar cannot be made compulsory for opening a bank account or getting a mobile connection.
- The provision that let private companies demand Aadhaar under a contract was struck down.
- Children cannot be denied benefits for lack of Aadhaar, and it is not required for school admission or for exams conducted by bodies such as CBSE.
Where Aadhaar can be required
Government welfare. Ration, LPG subsidy, pensions, scholarships and similar benefits can require Aadhaar authentication. But Sec 7 has a built-in safeguard: if you do not yet have Aadhaar, you must be offered an alternative and viable means of identification while you enrol. Fingerprints often fail for elderly people and manual workers; this should not mean denial of food or pension. Ask for iris or face authentication, an OTP, or the alternative your department allows.
Income tax. Income-tax law requires most PAN holders to link PAN with Aadhaar. If you do not, your PAN can become inoperative, which affects refunds and many financial transactions.
Authentication needs consent. Any agency authenticating you must take your consent and tell you how the information will be used Sec 8 Aadhaar Act. Your core biometrics (fingerprints and iris) cannot be shared.
Where it cannot be forced on you
After a 2019 amendment, banks and telecom companies may use Aadhaar for KYC (know your customer) checks only if you voluntarily offer it. You can instead give other officially valid documents such as a passport, driving licence, voter ID or NREGA job card, as the KYC rules allow. Rules amended in 2025 allow some approved private entities to offer Aadhaar authentication for their services, but again only on a voluntary basis.
Private employers, hotels, shops, gyms and housing societies have no general legal power to insist on your Aadhaar. If they need identity proof, offer another document or a masked Aadhaar, which hides the first eight digits. The QR code on the Aadhaar letter or e-Aadhaar allows offline verification without revealing your full number.
Step by step: protect your Aadhaar
- Download a masked Aadhaar from the UIDAI website and use it for routine identity checks.
- Lock your biometrics on the myAadhaar portal or the mAadhaar app, and unlock only when you need to authenticate.
- Check your authentication history on myAadhaar to see where your Aadhaar has been used.
- Keep your mobile number updated with UIDAI; OTPs go to that number.
- Never share an OTP with a caller. No bank or government office asks for it by phone.
- Mark photocopies with the purpose and date before handing them over, and do not leave copies with strangers.
Step by step: if you are wrongly denied or misused
- Ask for the legal basis. Ask politely which law requires Aadhaar for this service, and ask for the reply in writing.
- Offer an alternative identity document and note the response.
- Complain upward. Welfare schemes: the department's grievance officer, the district administration, or CPGRAMS. Banks: the bank's grievance system, then the RBI Ombudsman.
- Contact UIDAI on 1947 or its online grievance system for enrolment, update or misuse.
- Report fraud at once on 1930 and cybercrime.gov.in if money was taken.
Ramesh, 71, a retired mason in Nashik, is told at the pension camp that his old-age pension is "on hold" because his fingerprints do not match. His daughter writes to the taluka social welfare officer, quoting Sec 7 of the Aadhaar Act, and asks for iris or face authentication or another way to verify him. The officer arranges iris authentication at the camp the next week. The pension resumes, with the held amount.
The commonest myth is that "no Aadhaar, no service" is always lawful. For a bank account, SIM card, school admission or a private gym, it is not. For welfare, Aadhaar can be required, but a failed fingerprint must not end your ration or pension; insist on the alternative.

- Banks: bank grievance cell, then RBI Ombudsman at cms.rbi.org.in.

Common questions
Is Aadhaar mandatory for opening a bank account?
No. In K.S. Puttaswamy v. Union of India (2018) the Supreme Court held that Aadhaar cannot be made compulsory for bank accounts. After the 2019 amendment, a bank may use Aadhaar for KYC only if you voluntarily offer it; you can use other valid documents such as a passport, voter ID or driving licence.
Can a school refuse admission without Aadhaar?
No. The Supreme Court held in 2018 that Aadhaar is not required for school admission and that children cannot be denied benefits for not having it. If a school insists, ask for the rule in writing and complain to the district education officer.
Is Aadhaar proof of citizenship or date of birth?
Neither. Sec 9 of the Aadhaar Act says it is not proof of citizenship or domicile, and the Supreme Court held in 2024 that it is not conclusive proof of date of birth. It is proof of identity.
What if my fingerprints don't match for ration or pension?
Sec 7 of the Aadhaar Act requires an alternative means of identification. Ask for iris or face authentication, an OTP, or the department's alternative method. If you are still refused, complain in writing to the department and district administration.
How do I stop misuse of my Aadhaar?
Lock your biometrics on myAadhaar or the mAadhaar app, check your authentication history regularly, use a masked Aadhaar for routine checks and never share an OTP. If money is taken, call 1930 immediately.
