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. If you do not have access to your old mobile number, visiting an SBI branch may be required to update your registered mobile number, depending on the verification options available to you.
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 a 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.
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.
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:
That reference number matters. Within four hours:
If you miss the four-hour window, you'll need to raise it again.
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.
Different OTPs and a reference number are sent to the old and new mobile numbers. The required activation message must be sent from both mobile numbers within the specified time. You should now send ACTIVATE, followed by the OTP and reference number, to 567676 from both mobile numbers within 4 hours. SBI updates the record after both messages go through.
The 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.
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.
An SBI customer, Rohan Mehta from Delhi, faced this problem when he wanted to transfer Rs. 25,000 to his landlord. The OTP was sent to the old SIM that he had changed 8 months back. Using his Aadhaar Card and Passbook, he managed to change his number.
Three official ways exist to change your SBI mobile number, and which one fits depends entirely on whether your old SIM still receives messages. Update it the same week you switch numbers. Everything from OTPs to fraud alerts depends on that one detail being right.
Yes, under Profile, Change Mobile Number, there's a Status option showing your request outcome.
Not currently. Use net banking or an ATM instead.
No, all three methods of net banking, ATM, and branch are free.
Passbook along with another photo ID card such as Aadhaar or PAN and a duly filled-up request slip.
It takes 24 to 48 hours online or via an ATM, whereas more time at the branch.
Yes, the same Change Mobile Number section on SBI net banking has a Cancel Request tab where you enter your reference number.
Check the signal first and retry. If it keeps failing, head to your branch.
The update process for joint accounts may depend on the account's operating instructions and SBI's verification requirements. Customers should confirm the applicable process with SBI.
SBI customer care, 1800 1234 or 1800 2100, both toll-free, listed on the official SBI contact page.
Yes, they can help you, but the actual updating needs net banking, ATM, or a visit to a branch.
