How to link Aadhaar to a bank account?

blog

Let’s take an example of Gunal, it’s the year 2013 in the outskirts of Prayagraj, Uttar Pradesh. Here lives Mr. Gunal, a 45-year-old school teacher, who has the habit of arranging all of his government-issued documents, passport-sized photos, and other things in his file. He has a savings bank account, which has been operated since 1998. But in 2013, things have changed.

 

The bank informed its customers to link their Aadhaar cards. What was the scenario before this?

 

Bank customers need to submit:

  • Voter ID
  • PAN Card
  • Passport-sized photos
  • Ration Card

 

But in the year 2013, Aadhaar changed the banking realm. How? 

 

Mr. Gunaal got his 12-digit Aadhaar number from the Unique Identification Authority of India (UIDAI) after furnishing the required details.

  • Mr. Gunaal’s Aadhaar number: 123456789963 
     
  • Registered mobile number: 7999966666

 

How did he link?

 

Mr. Gunaal sends an SMS to the bank number 111999 by adhering to this format: 

  • UID <space> Aadhaar Number  <space> Bank A/C Number

 

So this is how he would have sent the SMS 

  • UID 123456789963 000987654321

 

Note: At least after a day, Mr. Gunaal’s bank account would have been linked with this Aadhaar number.

 

Why should you link your Aadhaar Card?

 

For Example, Kumaari, a 45-year-old widow from the outskirts of Chennai, runs a small tailoring shop and earns just ₹10,000–₹12,000 a month. When she didn’t link her Aadhaar to her bank account, she missed out on the ₹150 LPG subsidy, an amount that could’ve covered a week’s groceries. 

 

Realising the loss, she quickly linked her Aadhaar. From then on, she received ₹150 with every refill, adding up to ₹1,800 in a year, enough to pay her electricity bill. A simple step brought her real savings.

 

Key Takeaways:

  • Aadhaar linking is necessary to receive government subsidies.
  • Missing linkage may result in the loss of important financial benefits.
  • LPG subsidy of ₹150 per refill adds up over time.

 

How did the Aadhaar change Kumaari’s Life?

 

1. Direct Benefit Transfer 

 

Before Aadhaar:

  • Kumaari would visit the bank, which is 10 KM away from her home, in order to collect her subsidy amount. Many times, the bank would inform her to come another day, due to a delay in the dispersal of funds.

 

After Aadhaar:

  • All her LPG subsidies of ₹ 150 are directly credited into her bank account, which has amassed ₹ 1,800 after 12 months. 

 

2. Simplifying the KYC Process

 

Kumaari wanted to open a zero-balance Jan Dhan account to save his money

 

Before Aadhaar:

  • Banks demanded multiple ID proofs and a PAN Card.

 

After Aadhaar:

  • His 12-digit unique numbers and biometric fingerprint are enough to open the account.

 

3. Safety and Security 

 

Before Aadhaar:

  • Many times, Kumaari missed his ration quota of food grains, worth 25 kg. Indeed, the officer-in-charge of that shop used proxy signs of Gopal to scam his ration quota.

 

After Aadhaar:

  • Now, every time, Kumaari’s biometric verification and SMS verification are required to carry out the transaction. He will receive an SMS like 10 kg of rice and 10 kg of wheat have been issued to his registered mobile number.

 

4. Financial Inclusion

 

Kumaari is entitled to receive the Tamil Nadu Government’s Women's Assistance Scheme of ₹ 1,000 every month. 

Before Aadhaar

  • She needs to submit a PAN card, income proof, and other documents to support her eligibility.

After Aadhaar

  • The officials have examined her Aadhaar-linked Jan Dhan account to verify her income status.  Now she receives ₹ 1,000 every month.
