Indian Bank Mobile Number Change: Online & Branch Steps

Changing your Indian Bank mobile number takes minutes on net banking or the IndSmart app. You can also do it at an ATM or walk into a branch. Online requests need OTP checks on both the old and new number.

Log in to net banking or IndSMART, head to profile settings, and tap mobile number update. Type in the new number, confirm with OTP, and be done. Branch visits need a form plus ID proof.

Key Takeaways

1. There's no fee for changing your Indian Bank mobile number on net banking, the IndSMART app, at an ATM, or at a branch.
2. Banks are required to keep your registered mobile number current as part of routine KYC checks under the RBI's Master Direction on KYC, revised June 12, 2025.

Why does this even matter? Because every OTP, every fraud alert, every balance ping goes to the number that is in the bank’s system right now. Not the number you're currently using. A student switching cities, a retiree handing the SIM to a son, someone whose phone got stolen last week- all of them run into this at some point. Indian Bank gives you four ways to sort it out: net banking, the app, an ATM, or your branch. If you skip updating your mobile number, UPI, IMPS, and even simple net banking logins start failing.

Why You Should Keep Your Mobile Number Updated with Indian Bank

It’s updating the phone number tied to your account records. This is the number where OTPs, alerts, and fraud warnings land.

Indian Bank counts your mobile number as part of your KYC file, not a side detail. The RBI requires banks to keep this information current. So, every transaction can actually be traced back to the right person.

2. Fill in your account number, old number, and new number.

Can’t make it to a branch? Indian Bank also takes SMS and email requests for standard “no change” KYC declarations. Text 9677633000 from your registered number, or email rekyc@indianbank.co.in. A real number change, though, still needs an OTP or in-person verification. This route won’t skip that step.
