Introduction: The Digital Identity Revolution

Apply Aadhar Card Online Step By Step In the landscape of modern India, the 12-digit Aadhaar number has evolved from a novel initiative into a cornerstone of identity verification. Issued by the Unique Identification Authority of India (UIDAI), it is more than just a card; it is a robust, biometric-backed proof of identity and residence that seamlessly connects citizens to a multitude of services.

While the traditional process involved visiting an Aadhaar Enrollment Centre, the online application system has revolutionized accessibility, bringing the power to initiate the process right to your fingertips. This comprehensive guide will walk you through every step of applying for an Aadhaar card online, demystifying the process and ensuring you are equipped with all the necessary knowledge.

Part 1: Understanding Aadhaar and Pre-Application Essentials

Before diving into the application, it’s crucial to understand what you’re applying for.

What is Aadhaar?
Aadhaar is a random 12-digit number that serves as proof of identity and address. It is unique to each individual and remains valid for a lifetime. Its strength lies in its biometric foundation—it links your identity to your fingerprints, iris scan, and photograph—making it highly secure and verifiable.

Who is Eligible?

Resident of India:Any individual, irrespective of age or gender, who has resided in India for 182 days or more in the 12 months immediately preceding the date of application.
Newborns & Minors:Children can be enrolled. For children under 5 years of age, biometric data is not collected; only a photograph is taken. The child’s Aadhaar is linked to the parent/guardian’s Aadhaar. A mandatory biometric update is required when the child turns 5 and again at 15.

Mandatory Documents You Need (The Supporting Cast)
The online process begins with pre-booking an appointment, but the actual enrollment is physical due to biometric capture. You must carry original documents for verification. UIDAI accepts a wide range of documents categorized as:

Proof of Identity (PoI):Passport, PAN Card, Voter ID, Driving License, Ration Card, etc.
Proof of Address (PoA):Passport, Bank Statement, Utility Bill (water/electricity/gas), Property Tax Receipt, etc.
Proof of Relationship (For children):Birth Certificate, School ID card (with parent’s name), or a declaration from a hospital/gram panchayat.

Pro Tip: Always check the UIDAI’s official website for the latest and exhaustive list of acceptable documents. Carry at least one original document from each category you require (PoI and PoA).

Part 2: The Step-by-Step Online Application Process (The Pre-Booking)

Contrary to popular belief, you cannot complete the entire Aadhaar application from home. The online portal is used to pre-book an appointment at your nearest Aadhaar Enrollment Centre. Here is the detailed walkthrough:

Step 1: Visit the Official UIDAI Website
Navigate to the UIDAI’s official website: https://uidai.gov.in/ or the direct appointment booking portal: https://appointments.uidai.gov.in/. Beware of unofficial third-party websites that may charge fraudulent fees.

Step 2: Locate the ‘Book an Appointment’ Option
From the dropdown menu, select ‘Book an Appointment’. This will redirect you to the appointment booking system.

Step 3: Select Your Location and Center

Enter yourState, District, and Sub-District(Taluka).
The system will display a list ofPermanent Enrollment Centers (PCs)andAadhaar Seva Kendras (ASKs)in your area. ASKs are typically larger, more streamlined facilities. Choose one based on convenience and available slots.
You can also search by PIN code.

Step 4: Choose a Date and Time Slot
A calendar will display available dates. Green dates have open slots. Select a date and choose a convenient time from the listed options (e.g., 10:00 AM – 10:15 AM).

Step 5: Fill in Applicant Details
You will be prompted to enter:

Full Name(as per your PoI document)
Mobile Number(CRITICAL – all communication and OTPs will be sent here)
Email Address(optional but recommended)
Security Code (Captcha)

Step 6: Confirm and Note Your Appointment ID
Double-check all details. After confirmation, the system will generate a16-digit Appointment ID(e.g., 1234 5678 9012 3456).Save this number.You will receive an SMS with this ID and appointment details on your registered mobile number.

Step 7: Download the Appointment Letter (Optional but Advised)
You can download and print the appointment letter. While not always mandatory, it helps streamline the process at the centre.

Part 3: The Enrollment Centre Visit (The Core Process)

On the day of your appointment, arrive at the centre 10-15 minutes early with all documents.

Step 1: Document Submission and Verification
Present your original documents to the operator. They will verify them and return the originals to you immediately.

Step 2: Biometric Data Capture

Photograph:A digital photograph will be taken. Ensure your face is clearly visible.
Fingerprints:The fingerprints of all ten fingers will be scanned.
Iris Scan:Your iris pattern from both eyes will be captured.

Step 3: Data Entry and Review
The operator will enter the demographic details from your documents into the system. You will be shown a screen with all the entered data (name, address, date of birth, gender) for your final review. Scrutinize this carefully—this is your last chance to correct any spelling mistakes or inaccuracies before submission.

Step 4: Acknowledgment Slip
Once you confirm the details and the operator submits the data, you will receive a printed Aadhaar Enrollment Slip (Acknwoledgment Slip). This slip contains:

Your 14-digitEnrollment ID (EID)
Date and time of enrollment
A QR code
An enrolment number to track status

Guard this slip as carefully as you would the Aadhaar card itself. It is your only proof of enrollment until you receive your Aadhaar number.

Part 4: Post-Enrollment Steps and Tracking

Step 1: Track Your Aadhaar Status
Visit the ‘Check Aadhaar Status’ page on the UIDAI website (https://uidai.gov.in/). Enter your 14-digit Enrollment ID (EID) from the acknowledgment slip, the date and time of enrollment (printed on the slip), and the security code. The portal will show whether your Aadhaar has been Generated, Under Process, or if there is an Issue/Rejection.

Step 2: Download Your Aadhaar (e-Aadhaar)
Once the status shows “Generated,” you can download your e-Aadhaar. This is a password-protected PDF file. The password is your PIN code (if your address has a PIN code) or the first 4 letters of your name in CAPITAL letters followed by your birth year in YYYY format (e.g., RAMA1990).

Go to ‘Download Aadhaar’ on the UIDAI website.
You can use your EID or your Aadhaar number (if received via SMS) to download.
Thee-Aadhaar is equally valid as the physical cardunder the IT Act.

Step 3: Receive Your Physical Aadhaar Letter
UIDAI dispatches the physical Aadhaar card via India Post to your registered address. This can take several weeks to a couple of months. You can track the postal status on India Post’s website using the UIDAI reference number sent via SMS.

Part 5: Special Considerations and Troubleshooting

For Newborns/Children:The process is identical, but the biometrics of one parent/guardian are taken for linkage. The child’s photo is taken. Remember to carry the child’s birth certificate and the parent’s Aadhaar.
Updating Details:If you need to correct your name, address, date of birth, etc., after receiving Aadhaar, you must use the“Update Aadhaar”service online or at an enrollment centre. This is a separate, detailed process with its own fee structure.
“Aadhaar not generated” / Rejection:If your enrollment is rejected, it is usually due todocument mismatch, poor biometric quality, or potential duplicate enrollment.The status portal will generally indicate the reason. You will need to re-enroll with correct/verified documents.
Lost Enrollment Slip:If you lose your acknowledgment slip, you can retrieve your EID using the ‘Retrieve Lost UID/EID’ service on the UIDAI website using your registered mobile number.

The visit is an unavoidable and critical part of the process.

2. What is the cost of applying for an Aadhaar card?
Enrollment for a new Aadhaar is absolutely free of cost. You should not pay any money at the enrollment centre for a fresh enrollment. However, if you later wish to update your demographic details (like address) or biometrics, a nominal fee is charged as per UIDAI regulations. Be wary of centres or agents demanding money for a new enrollment.

First, download youre-Aadhaarfrom the UIDAI website—it is legally valid. To track the physical letter, use the “Check Aadhaar Status” service. Once generated, an SMS is sent with aPostal Dispatch ID.

4. How long does it take to get the Aadhaar number after enrollment?
Typically, if the enrollment is successful and without issues, your Aadhaar number is generated within 30 to 90 days of enrollment. You will receive an SMS on your registered mobile number once it is generated. You can then immediately download the e-Aadhaar. The physical card takes additional time for printing and postal delivery.

5. Is Aadhaar mandatory for all citizens?
While the Supreme Court has ruled that Aadhaar cannot be made mandatory for availing essential services (like admission to school or hospital treatment), it is compulsory for filing Income Tax Returns (ITR), receiving certain government subsidies and welfare benefits, and for obtaining a Permanent Account Number (PAN). For most other private and public services, it is one of the most convenient and widely accepted Know Your Customer (KYC) documents.
