Banking in India has changed rapidly over the last decade. Visiting a branch, filling long forms, and maintaining a minimum balance are no longer the only options. With the growth of smartphones, Aadhaar-based verification, and instant payments, mobile numbers have become central to financial identity.
Many banks now offer Mobile Number Based Zero-Balance Savings Account in India where the registered mobile number plays a key role in identification, access, and daily transactions. These accounts are especially popular among users who want simple, paperless, and fully online banking. This article explains how such accounts work, their benefits, limitations, and what users should know before opening one, with a focus on digital platforms like IndusInd Digital Savings Account and Kotak 811.
What Is a Mobile Number–Based Savings Account?
A mobile number–based savings account is a regular bank savings account where the registered mobile number acts as the primary reference point for communication, login, and transaction alerts.
Key points:
- The mobile number is linked to the bank account, not a replacement for it
- It is used for OTPs, UPI, alerts, and customer identification
- The actual account number still exists in the bank’s Core Banking System (CBS)
In traditional banking, customers mostly used the account number for reference. In modern digital banking, the mobile number simplifies access and identification, while the banking infrastructure remains the same in the background.
What Is a Zero-Balance Savings Account?
A zero-balance savings account allows customers to:
- Open and maintain an account without keeping a minimum balance
- Avoid penalties for low balance
These accounts are based on guidelines issued by the Reserve Bank of India for Basic Savings Bank Deposit Accounts. Banks may offer additional digital features while following these core rules.
Who Should Consider Opening This Type of Account?
Mobile-based zero-balance accounts are suitable for:
- Students and first-time bank users
- Homemakers managing household expenses
- Salaried and self-employed individuals
- People who prefer fully digital banking
- Users focused on UPI and online payments
They are especially useful for those who want banking without frequent branch visits.

At this stage, your application enters the bank’s verification system.
