Want to change your registered mobile number with Union Bank of India? You've got four ways to do it: net banking, the Vyom app, an ATM, or your home branch. All four need an OTP at some point. Branch requests take the longest, usually a day or two.
Log in to Union Bank net banking, go to your profile, and change your mobile number there with an OTP. In case you can’t access net banking or have a lapsed KYC, go to the nearest branch carrying along the ID proof.
Lost your SIM? You stop getting OTPs, balance alerts, fraud warnings, all of it, until the bank has your correct number again. Every Union Bank of India customer runs into this sooner or later. Maybe the phone got stolen. Perhaps you recently changed your operator, and now your old SIM is dead. The process is not that complicated, but many find it difficult to know how to do it. That’s why we’ve described each one separately. The RBI also expects banks to keep contact details current, something it lays out in its KYC Master Direction.

Ask for the mobile number change form, fill it in, and submit it with your documents.

If your KYC has expired, online options simply won't work, so a branch visit becomes your only route. Same story if you lost both your phone and the SIM that was registered with the bank, since there's no number left to send an OTP to. It feels a bit old-fashioned, sure, but it's still the fastest fix in those two cases.

Mostly three things: proof of identity, proof of address, and a couple of photos.
Net banking and ATM changes go through fast, often within minutes of the OTP being entered. Branch requests sit somewhere between 24 and 48 hours before the new number appears in bank records. Past that window with no update? Call the branch and ask them to check.
Open net banking or the Vyom app and check “My Profile” or “Account Information.” The registered number sits right there. Or just ring customer care on 1800 425 1515 or 1800 425 3555 and have them confirm it on the spot.
No. Union Bank doesn't charge for this update, whichever method you use: net banking, Vyom, ATM, or branch. The only real cost is printing or photocopying documents if you go with the branch route.
An outdated mobile number with Union Bank of India is more than a small annoyance. It's a real security gap. If your KYC is active, log in and fix it online in a few minutes. If it's expired or your SIM is gone, a branch visit with the right documents sorts it out within a couple of days. Either way, confirm the change through your profile or customer care once it's done. Don't just assume it went through.
Yes, as long as net banking or the Vyom app still logs you in, the whole thing can be done online.
Check your signal first, then request the OTP again. Still nothing after that? Time for a branch visit.
No, PAN Card and Passport work too, so use whichever you have on hand.
No. A call alone won't do it. You need net banking, an ATM, or a branch visit to actually process it.
Probably. Apps like Google Pay or BHIM usually need re-registration once your linked number changes.
Your branch or the net banking dashboard usually flags it. When unsure, just ask your branch directly.
No, it has to come from the account holder since OTP and signature verification are both required.
You'll miss transaction alerts and OTPs, and that quietly raises your fraud risk over time.
Union Bank hasn't published a specific cap, though changing it too frequently might invite extra checks.
Not really. It's the same branch or net banking route, though some branches may ask NRIs for extra paperwork.
