Why Aadhaar matters
Aadhaar is the central digital identity system in India that provides each resident a unique 12-digit number. UIDAI issues Aadhaar after verifying demographic details (name, date of birth, address) and capturing biometric data (photograph, fingerprints, and iris scan). Over the last decade Aadhaar has become deeply integrated with public and private systems: it is used for direct benefit transfers, public distribution systems, LPG subsidy transfers, income tax filings, and for KYC by banks and telecom operators.
From an individual's perspective, Aadhaar simplifies identity verification for opening bank accounts, obtaining mobile connections, applying for government benefits and verifying identity online (through e-KYC). However, with broad utility comes responsibility — you should understand privacy controls (masked Aadhaar, virtual IDs) and avoid sharing the full Aadhaar number unnecessarily.
Important: UIDAI is the authoritative source for rules and forms. Always confirm document lists and procedures on uidai.gov.in or authorised state portals before visiting an enrolment centre.
Ways to apply for Aadhaar
There are two main ways to initiate Aadhaar enrolment for first-time applicants:
- Walk-in enrolment at an authorised Aadhaar centre: Visit a UIDAI-authorised enrolment centre (Aadhaar Seva Kendra, bank/CSC/authorized private centre) with original documents. Operator will verify documents and capture biometric data on-site. This is the mandatory step for first-time enrolment.
- Book an appointment online and then visit: Use UIDAI’s appointment portal to reserve a time slot at many Aadhaar Seva Kendras — this reduces waiting time and ensures the centre is ready to process your application at the booked time.
Note: You cannot complete first-time enrolment fully online because the biometric capture must be done in person.
Complete document checklist (what to carry)
UIDAI maintains a list of accepted documents for Proof of Identity (PoI), Proof of Address (PoA), and Proof of Date of Birth (DoB). Below is an expanded, practical checklist and examples to help you prepare before the centre visit.
Primary documents commonly accepted
| Document Type | Examples and notes |
|---|---|
| Proof of Identity (PoI) | Passport; PAN card (note: PAN has full number visible); Voter ID (EPIC); Driving Licence; Government/PSU photo ID; Distinguished by presence of photo and name. |
| Proof of Address (PoA) | Passport; Voter ID; Driving Licence; Recent utility bill (electricity, water, gas) not older than specified timeframe; Bank statement/passbook with recent entries; Ration card showing address. |
| Proof of Date of Birth (DoB) | Birth certificate; Passport; SSLC/10th standard certificate; Municipal birth register; School leaving certificate. |
| Proof of Relationship (PoR) | Sibling/parent/spouse documents used when applying for children's Aadhaar; marriage certificate for spouse linkage; parent documents for minors. |
Practical tips:
- Carry both original documents and a set of photocopies. Many centres scan the originals and return them immediately — but photocopies speed up the process.
- If you have multiple PoI/PoA documents, bring them all — this helps in case the centre requires a particular category for your case.
- For address proof, prefer a government-issued document (passport, voter ID) or a recent utility bill (within 3 months) where applicable.
Special document notes: Birth dates for newborns and recent births may have specific documentary requirements. For children and certain age groups, UIDAI may have mandated forms and supplementary proofs — check UIDAI’s current valid documents PDF before visiting.
How to book an appointment (step-by-step)
Booking an appointment is not mandatory, but highly recommended, especially in urban centres where queues and waiting times can be long. Booking ensures a confirmed slot and prevents long waiting periods.
How to book
- Open the UIDAI appointment portal (check the official UIDAI website for the latest booking link).
- Choose the service: "Enrolment" for new Aadhaar, or "Update" for corrections/changes.
- Enter applicant details (name, contact number, email — contact is optional but useful for reminders).
- Select state → district → local Aadhaar Seva Kendra from the list.
- Pick a convenient date and time slot and confirm booking. Note the booking ID and take a screenshot/print the booking confirmation.
Tip: If you’re booking for a family, most portals allow multiple registrations in one appointment; check the portal options.
What to do before visiting the enrolment centre
Preparing ahead makes the actual centre visit quick and painless. Follow this checklist before leaving home:
- Gather all original documents and photocopies in order (PoI, PoA, DoB as applicable).
- Carry any supporting documents for special situations (guardian ID for minors, NRI documents for overseas applicants).
- Charge your phone and keep a power bank — you may need to receive OTPs or confirmations.
- Carry a list of common spelling variants of names if your documents contain regional spellings. This helps when confirming the exact spelling at the centre.
- Leave extra time for travel — some centres are in busy government complexes with security checks.
Accessibility: Many Aadhaar Seva Kendras are accessible; if you or a family member need assistance, call the centre beforehand to request support or priority assistance.
Step-by-step: What happens at the Aadhaar enrolment centre
This section walks you through the typical flow at an authorised centre. While the exact screens and labels may vary slightly, the core steps are consistent across centres.
1. Document verification
The operator will ask for original documents and cross-check them against the list you submitted while booking (if you booked). They will note which documents are being used for PoI, PoA and DoB and may scan or photocopy them.
2. Demographic data entry
The operator enters your demographic details (name, gender, date of birth, address, mobile number, email). This is a crucial step — carefully review the entered details on the preview screen. Ask the operator to correct any spelling mistakes before final submission.
3. Biometric capture
Biometrics captured typically include:
- Photograph (live capture at the centre).
- Ten fingerprints (or available fingers if some are not readable).
- Iris scan (if applicable).
For applicants with missing, damaged or unreadable fingerprints (for example, manual labourers with worn prints), the operator notes the condition. UIDAI has procedures for such cases — bring alternative proofs and explain the situation to the centre staff.
4. Preview & consent
Before final submission, you will be shown a preview of the entered details. Confirm spellings, date of birth and address. You will then be asked to sign the acknowledgement and provide consent for enrolment and biometric capture.
5. Acknowledgement slip (EID)
Once the operator completes data capture, you will receive an acknowledgement slip with a 14-digit Enrolment ID (EID) and date/time. Keep this slip safe — it is required to check the status of your application and to download e-Aadhaar if needed.
Do not lose your EID: EID is the primary tracking reference until a 12-digit Aadhaar number is generated and assigned.
Acknowledgement (EID), processing & timelines
After enrolment, UIDAI processes the data, verifies documents and performs de-duplication checks against the national database. The timeline for generation of Aadhaar varies: it can take a few days to several weeks depending on the verification queue and complexity (for example, if manual checks are needed).
Typical flow after submission:
- Data uploaded from enrolment centre → UIDAI processing queue.
- Verification & de-duplication checks.
- If approved, Aadhaar number generated and linked to the EID; UIDAI may send an SMS to the registered mobile number (if provided).
- Once Aadhaar number is generated, e-Aadhaar becomes available for download from UIDAI’s portal using Aadhaar/EID + OTP verification.
If you do not get SMS updates, use the EID and date/time from the acknowledgement slip to check status online.
How to check Aadhaar enrolment status and download e-Aadhaar
Check status
- Go to UIDAI’s “Check Enrolment/Update Status” page (use official website link).
- Enter the 14-digit Enrolment ID (EID) and the Date/Time printed on the acknowledgement slip.
- Submit to view the current status: Under Process, Rejected, or Aadhaar Generated.
Download e-Aadhaar
Once Aadhaar is generated, you can download a digitally-signed e-Aadhaar PDF from UIDAI’s “Download Aadhaar” service using either:
- Your Aadhaar number (if generated) + OTP sent to registered mobile.
- Enrolment ID (EID) + OTP to registered mobile (if Aadhaar number not yet issued but available for download).
e-Aadhaar is password-protected. The password is a combination of the first four letters of your name (in CAPITAL letters) followed by your birth year (YYYY). Example: Name: RAHUL KUMAR, DOB: 1992 → password: RAHU1992.
Fees, charges and optional paid services
First-time enrolment: Free at UIDAI-authorised centres.
Paid services (examples):
- Printed Aadhaar letter delivery (if requested from third-party service providers) — nominal fee may apply.
- Offline biometric update or demographic updates at some private centres — check the fee schedule at the centre.
- SSUP (Self Service Update Portal) online updates: some updates may be free while others have nominal charges (check UIDAI’s portal).
Always ask the operator to show the fee schedule before paying any charges and insist on a printed receipt if you pay cash.
Special cases & instructions
Children & minors
Children can be enrolled in Aadhaar. For very young children (below a certain age), biometrics may not be collected initially. UIDAI typically requires biometric updates at age 5 and again at 15 (confirm current policy on UIDAI site). Parents/guardians must provide their documents and proof of relationship when enrolling a child.
Residents without documents
If an applicant genuinely has no documents, some local processes or documentary alternatives may be available (introducer-based verification in exceptional cases, district officer guidance). However, UIDAI generally requires at least one acceptable document. If you face this situation, contact your local Aadhaar Seva Kendra or district administration for help.
NRIs & overseas applicants
NRIs can apply for Aadhaar when they are present in India and meet residency criteria. Some forms and PoA options are NRI-specific — check UIDAI’s guidance for overseas residents or update forms for NRIs.
Disabled persons & assisted enrolments
UIDAI provides accommodations for persons with disabilities. If you need assistance, ask the centre for help or request priority service. Many centres reserve priority slots for elderly and differently-abled applicants.
How to update or correct Aadhaar details later
UIDAI allows updates to certain demographic details (name, address, date of birth, gender, email, mobile) and supports biometric updates under limited conditions. There are two broad ways to update:
1. Online updates (SSUP - Self Service Update Portal)
Some demographic updates (e.g., address) can be updated online using UIDAI’s SSUP. These updates usually require scanned copies of supporting documents and OTP-based authentication. Use the portal for address changes when you have valid PoA documents.
2. Offline updates at an enrolment centre
For certain corrections like name change (with supporting documents), or biometric updates, you must visit an Aadhaar centre and submit your request. There may be nominal charges for offline updates; keep the receipt and update request acknowledgement.
Important: When requesting an update, always verify which documents are accepted for that specific update type — UIDAI updates this list from time to time.
Privacy, security & fraud prevention
Aadhaar contains sensitive personal and biometric data — treat it with caution. Follow these safety tips:
- Share Aadhaar only with trusted and authorised entities. Prefer using masked Aadhaar (showing last 4 digits) for KYC where possible.
- Use UIDAI’s Virtual ID (VID) for authentication instead of sharing Aadhaar number directly in some services.
- Download e-Aadhaar only from UIDAI’s official website and verify the digital signature when required.
- Do not accept or open unsolicited emails claiming to be e-Aadhaar attachments — use official portals.
- If you suspect misuse, report to UIDAI and local authorities immediately.
Quick security checklist: Keep your EID safe, enable OTPs on your mobile, never share OTPs with anyone, and use masked Aadhaar for third-party checks.
