New UIDAI Aadhaar Rules: One Card Per Person, Check Out This Updated Document List

The Unique Identification Authority of India (UIDAI) has introduced a fresh set of changes for its Aadhaar enrolment process and updated rules. This is UIDAI’s effort to bring in tighter checks and standardisation.

Under the recent changes, which came into effect from July 2, the UIDAI has introduced a clear ‘one person, one Aadhaar’ rule and an updated list of valid documents for enrolment and modification.

One Aadhaar, No Duplicates

This is one of the most significant rules and that is you can only have one Aadhaar number. If you have ended up with more than one Aadhaar over the years, maybe due to technical errors or reapplications, only the first one issued with biometric data will stay valid.

Any others linked to the same individual will be cancelled. This is part of UIDAI’s push to clean up duplications in the Aadhaar database, something that has been quietly bothering the system for a while.

Updated Document List

The document list for Aadhaar-related services has also been updated under the Aadhaar (Enrolment and Update) First Amendment Regulations, 2025.

The new list clearly outlines what documents can be submitted as proof of identity, address, relationship, and date of birth. Some things have not changed, for instance, your Indian passport continues to be the most versatile document, accepted across all four categories. But beyond that, there are new checks on what is valid and what’s not.

For example, if you are submitting a bank passbook or a voter ID as address proof, the document has to be current and verifiable, either digitally or through UIDAI’s systems. If the issuing authority has, at any point, stated that a particular document should not be treated as valid proof (say, for address or relationship), UIDAI will not accept it anymore.

Key acceptable documents are:

Identity proof, which includes PAN card, voter ID, driving licence, and government-issued photo IDs.

Address Proof, including utility bills, bank passbooks, ration cards, and government housing documents.

Date of Birth related proof like Birth certificate, passport, or SSLC book.

Relationship Proof documents include PDS card, an MGNREGA job card, or birth certificates showing parents’ names.

Children aged below five can be enrolled either via a “Head of Family” process or through individual documentation.

What About Foreign Nationals?

The rules also spell out separate documentation for non-resident categories, including Overseas Citizens of India (OCI), Long Term Visa (LTV) holders, and citizens of Nepal, Bhutan, and other foreign nationals.

These applicants will need to provide a mix of foreign passports, visas, FRRO-issued permits, or citizenship certificates, depending on their profile.

Changing your name, gender, or date of birth? This is also going to need a bit more paperwork now. In many cases, things like a gazette notification, medical certificate, or a birth certificate accompanied by a self-declaration may be required.

Those who are currently applying for an Aadhaar card or need to update it can view the full list of updated documents and details for each category on UIDAI’s official website or from the official notification.
