SBI Mobile Number Change: How to Update Your Registered Number?

SBI lets you change your registered mobile number through net banking with ATM approval, directly at an ATM, or at your branch. The first two are free and usually done within a day. A branch visit is needed only if your old number is dead.

Key Takeaways

• Net banking and ATM updates need your active debit card and old number, and both are free.
• Lost your old SIM? A branch visit is your only option, and it can take a few working days.

If you just switched your SIM card, the OTPs are still landing on a number you no longer own. That's usually what brings people here. That’s usually what brings people here searching for how to change mobile number in SBI. This page covers the three routes SBI offers for it. You’ll find who can use each one, what to carry, and roughly how long each takes. It applies to any SBI savings or current account, and none of the three methods below cost anything.

What is SBI Mobile Number Change?

It’s updating the phone number tied to your account so OTPs, SMS alerts, and YONO login shift to your current SIM. SBI stores this number against your Customer Information File, so one update covers every account under that same CIF.

If you skip this step after a SIM swap, fund transfers stall at the OTP screen. Fraud alerts go to a stranger’s phone. Password resets on YONO simply don't arrive.

Why does SBI ask you to keep this Number Updated?

Because every OTP, every debit alert, and every login confirmation depends on it. There's no workaround inside net banking or YONO if the number is wrong.

Three things stop working the day your old SIM dies:

• OTP confirmation for transfers, bill payments, and card purchases
• Real-time SMS alerts for debits and credits, which is often how people catch fraud early
• YONO password or MPIN recovery, which routes only through the registered number

How to change Mobile Number in SBI through an ATM?

No login required here, just your debit card and PIN. At the ATM, choose Services, then Registration, then Mobile Number Update, and select either fresh registration or a change to an existing number.

SBI will send OTPs to both your old and new mobile numbers after you have registered the new phone number. You should now send ACTIVATE, followed by OTP and reference number to 567676 through both the mobile numbers in 4 hours. SBI updates the record after both messages go through.

What If You Don't Have Access to Your Old Number?

 Branch is your only route, since net banking and ATM both depend on an OTP to the old number for verification. You should visit the branch with your passbook, any one of the valid ID proofs like Aadhaar or PAN Card, along with the filled-up request form available at the branch. Your signature is then verified, the number is changed in the core banking system, and you get an SMS confirmation after that. There's no fee here either.

How long does the Update actually take?

Net banking and ATM requests usually reflect within 24 to 48 hours after the OTP step clears. Branch requests take longer, sometimes stretching to a week depending on the branch and account type.
