There are four official ways to do a UCO Bank update mobile number request. Use the mBanking Plus app, visit your home branch, go through WhatsApp Banking's Re-KYC menu, or fill out the Re-KYC form. All four end the same way, with the branch punching your new number into Finacle.
Lost your SIM? Switched telecom providers? Bought a new phone with a new number? Then your UCO Bank account needs an update. The bank sends OTPs, transaction alerts, and login codes to whatever number sits on file. Once that number stops working, m-banking, e-banking, and UPI all get harder to use. Four channels exist to fix this, and you can pick whichever fits your situation.
You can update your mobile number through the UCO mBanking Plus App by following these steps:
How to Update Your UCO Bank Mobile Number at the Branch?
SIM lost, blocked, or dead? Skip the app and walk into your branch.
No app, no branch trip. Just WhatsApp.
Due for a periodic KYC update anyway? This one covers both jobs at once.
*T&C Apply
Is the old number completely dead? The branch might ask for an extra declaration, since the usual OTP check has nothing to work with.
Disclaimer: The above-mentioned information is tentative in nature, borrowers are advised to check the official website or contact the customer service for up-to-date information regarding the same.
No fixed fee shows up on UCO Bank’s official FAQ page for this service. Some branches apply standard charges depending on your account type. Ask your branch directly before you submit anything. Any website quoting a flat number isn’t backed by the bank’s own published tariff, so treat those figures with caution.
One working day, usually, once the branch keys in the change. Using UCO m-Passbook too? That’s a separate step. You'll need to link the new number with your customer ID through the base branch, since m-Passbook doesn’t sync with the mobile banking update on its own.
Conclusion
Four paths, one outcome. Pick the app if your SIM still works. Walk into the branch if it doesn't. WhatsApp and the Re-KYC form sit somewhere in between, useful if you’d rather avoid a queue. Keep your ID proof handy either way.
Can I UCO bank update mobile number without visiting a branch?
Yes. Use the mBanking Plus app if your old number works, or try WhatsApp Banking’s Re-KYC option.
Where in the app do I find the mobile number update option?
Under “My Profile.” The app lists “Update Mobile Number” as its own menu item.
What happens to my old number after the update?
It goes dead for OTPs and alerts once Finacle reflects the change, usually within 24 hours.
Is the Re-KYC form only for KYC renewal, or can I use it just to change my number?
Just for the number works fine. The Re-KYC form has a field built specifically for contact detail updates.
How do I submit the Re-KYC form?
Email, courier, post, or in person at your nearest or home branch. Pick whichever is fastest for you.
How do I start a mobile number update on WhatsApp Banking?
Save the number, send “Hi,” choose your language, then pick Re-KYC from the menu.
Does UCO Bank charge a fee for mobile number updates?
Nothing fixed appears on the official FAQ page. Confirm with your branch before you go in.
Is UPI affected if I change my mobile number?
Yes. UPI runs on SIM binding, so plan on re-registering your UPI app after the switch.
Do I need my old mobile number to complete the update?
For the app, yes, since verification leans on your existing login and debit card. For the other three routes, a dead old number won’t stop you.
What if I also use UCO m-Passbook?
Link your new number with your customer ID through the base branch separately. It doesn’t update on its own.
