Changing your SBI mobile number: online, at an ATM or at the branch
Your bank’s alerts and OTPs go to the mobile number it has on record. If that number is old, lost or about to lapse, change it before anything else. SBI offers three ways: online, at its ATMs and at the branch. This guide helps you pick one and walks through each, based on SBI’s own instructions. IFSC Bank Guide is independent and not linked to SBI.
Why the number matters
The RBI tells banks to ask every customer to register for SMS alerts, and says electronic transactions other than ATM cash withdrawals should not be offered to customers who do not give a mobile number. Your number is how the bank tells you that money has moved, and how it checks that you are you.
- Alerts are your early warning. For transactions from 1 January 2027, the RBI’s new rules give you five calendar days to report a fraud for the strongest protection. If the alerts go to an old number, you may not learn of a fraud in time.
- OTPs go to the registered number. Lose access to it and you can be locked out of internet banking and UPI.
- Old numbers get reused. Mobile operators can give a disconnected number to a new customer after a while. Change your number with the bank before you let the old one lapse.
Which way suits you
Answer three questions. Your answers stay on your device.
Online, through OnlineSBI
SBI’s internet banking site is now at onlinesbi.sbi.bank.in; the old addresses redirect there. Type it yourself rather than following a link from a message.
- Log in to OnlineSBI. Not registered yet? SBI says you can register online with your ATM-cum-debit card.
- Open the profile. Under My Accounts, go to Profile, then Personal Details, then Change Mobile Number. The profile section asks for your profile password, which is separate from your login password.
- Enter the new number. Choose the account and type the new number. SBI shows the last two digits of the number it has now, so you can check it is the right account.
- Approve the change. The screen lists the approval options you can use. These usually include OTPs sent to both the old and the new number, or approval at an SBI ATM with your debit card, which SBI calls IRATA (Internet banking Request Approval Through ATM). Finish within the time the screen gives you.
- Wait for the confirmation. SBI says it sends the status of the change by SMS.
At an SBI ATM
These steps follow SBI’s own guide. You need your SBI debit card, its PIN, and both phones.
- At an SBI ATM, choose Registration and enter your PIN.
- Choose Mobile Number Registration, then Change Mobile Number.
- Enter the old number and confirm it, then the new number and confirm it.
- Reply from both phones within 4 hours. SBI sends a different OTP and a reference number to each number. From each phone, send an SMS to 567676 in the format the message gives you: the word ACTIVATE, then the OTP and the reference number.
- Wait for the confirmation SMS. If 4 hours pass, start again.
Shield the keypad when you type your PIN, and never accept help from a stranger at the ATM.
At the branch
SBI’s guide says to fill in a letter of request at your branch. After verification the branch links the new number and you get an SMS about it. This is the route to use if the old SIM is gone. Take your passbook or account details and an identity document; the branch will tell you if it needs anything else.

After the change
- Check the alerts. Make a small transaction or a balance check and see which phone gets the SMS. If it still goes to the old number, ask the branch to update the number used for alerts.
- Set up UPI again. UPI apps check that the SIM of your bank-registered number is in the phone. Put the new SIM in, then register again in each UPI app. If you used UPI Lite, switch it off first; the balance goes back to your account.
- Set up the SBI app again. YONO and other banking apps may ask you to register again on the new number.
- Update the other places. Aadhaar, PAN, other banks, demat and mutual fund accounts, insurance and EPFO keep their own records. Changing SBI changes none of them.
- Keep the old SIM for a few days if you can, so that you do not miss a last OTP or alert.
An invented example
Scams that use “mobile number update”
- “Your account will be blocked today. Update your number or KYC here.” Banks do not ask you to update details through a link in an SMS or WhatsApp message. Go to the branch or type the bank’s address yourself.
- “Install this app to redeem reward points or update your number.” An app file (APK) sent on WhatsApp can read your SMS and steal your OTPs. Install banking apps only from the official app store.
- “Tell me the OTP and I will update your number.” SBI says it never asks for confidential details such as your PIN or OTP. Anyone who does is a fraudster, whatever name or caller ID they show.
- Your SIM suddenly stops working. If your phone loses network without reason, call your operator and your bank from another phone at once. A SIM swap lets a fraudster receive your OTPs.
- Already lost money? Call 1930 and read the first 24 hours after a fraud.
For bank staff: the counter checklist
- Verify the customer’s identity before taking a mobile number change, and be extra careful when the request comes with urgency or from someone other than the account holder.
- Explain the three routes, so that customers with both SIMs and a debit card can do it themselves next time.
- For a customer whose old SIM is lost, take the letter of request; the online and ATM routes will not work for them.
- After the change, remind them to set up UPI again, switch off UPI Lite first, and check that alerts reach the new number.
- Remind them that the bank never asks for an OTP or PIN, and never sends links or app files to update details.
Questions people ask
Can I change my SBI mobile number online?
Yes, through OnlineSBI if you use SBI internet banking. SBI’s guide puts it under My Accounts: Profile, then Personal Details, then Change Mobile Number. The change has to be approved, usually with OTPs on both the old and the new number.
How do I change my SBI mobile number at an ATM?
At an SBI ATM, choose Registration, enter your PIN, then Mobile Number Registration and Change Mobile Number. Enter the old number, then the new one. SBI sends a different OTP to each, and you must reply from both numbers to 567676 within 4 hours.
I lost my old SIM. How can I change the number?
Go to your branch with a written request and your identity document. Or ask your mobile operator for a replacement SIM on the same old number; once it works, you can use the online or ATM route.
Is there a fee to change the mobile number?
SBI’s guide mentions no fee for any of the three routes. Anyone who asks you to pay to “update” your number is very likely a fraudster.
Will my UPI work after I change the number?
Not straight away. UPI apps check that the SIM of your bank-registered number is in your phone, so put the new SIM in the phone and set up UPI again in each app.
Does changing my number with SBI change it for Aadhaar too?
No. Aadhaar, PAN, other banks, demat and mutual fund accounts, insurance and EPFO each keep their own record. Update each one separately.
