How Do I Change My Mobile Number at a Union Bank Branch?

1. Visit your home branch, or any other branch if that's easier, and ask for the "Data Updation Form Under KYC Compliance" (labelled Annexure III on the form).
2. Fill in your account number, Customer ID, and your new mobile number in the field marked "Mobile No."
3. Carry along your ID proof. A PAN card or Aadhaar card will work.
4. You will require two passport-size photographs as well.
5. Submit the duly filled form to the officer at the branch for verification.
6. Request the acknowledgement slip copy before leaving.

How to fill the Union Bank KYC Data Updation form?

The form is one page, and Union Bank hosts it directly on its site as a downloadable PDF. You don't have to fill it out in advance, but it saves time at the counter if you do. Here's what goes where:

• Name, Address, Customer ID, Account No.: top of the form, matched exactly to your passbook.
• Address checkbox: tick "There is No Change in my current address" if you're only there for the mobile number. Skip this, and the branch may treat it as an address update too.
• Mobile No.: Your new number goes here. This is the field the whole visit is for.
• Tel. Office / Residence / Email ID / Father's Name / Mother's Name / DOB / PAN: standard KYC fields, only needed if that information has changed. Ask the officer if you're not sure what applies to you.
• Signature: Match what's already on file with the bank.
• Photo: Attach a passport-size photo where indicated.

Branches sometimes hand out a slightly revised version of the form, so if yours looks different, just ask the officer what's changed.

What Documents Do You Need for a Union Bank Mobile Number Change?

Mostly three things: proof of identity, proof of address, and a couple of photos.

How Long Does the Union Bank Mobile Number Update Take?

Most branch requests show up in bank records within 24 to 48 hours, based on what customers typically report. Union Bank doesn't state this timeline officially anywhere. If it's taking noticeably longer, call the branch and ask them to check on your request.

How Do You Check If Your New Mobile Number Is Updated?

You can try Union Bank's toll-free numbers, 1800 8333, 1800 2333, 1800 8331 or 1800 8332, and ask customer care to check the number on file. Or take your acknowledgement slip back to the branch and ask there.

Are There Any Charges for Changing Your Mobile Number?

Union Bank does not appear to charge for this update through the branch process based on available information. Any cost you're likely to run into would be for printing or photocopying documents you already have.

Conclusion

An outdated mobile number with Union Bank of India can cost you fraud alerts you should have gotten. The branch visit takes some planning, but it's the one method Union Bank actually confirms on its site, and it's usually done within a couple of days. After you submit the request, it's worth calling customer care or checking with your branch to confirm it actually went through, rather than assuming it did. 

FAQs

1. Can I visit any Union Bank branch, or only my home branch? 

Yes, any branch works. Union Bank includes mobile number and KYC updates in what non-home branches can handle, so your home branch isn't a requirement.

2. Is Aadhaar the only accepted ID for a branch request? 

No, a PAN card or Passport works too, so bring whichever one you have on hand.

3. Can customer care change my number over a phone call? 

The updating of the mobile number may require identity proof that is not possible over a telephone call. If you wish to get information about the possibilities you have, contact the customer care centre.

4. Will my UPI apps need updating after this? 

Google Pay, BHIM, and similar apps are usually linked to your registered number. Once it changes, you may need to re-register them.

5. How do I know if my KYC has expired? 

Your branch will usually flag it when you visit. Or skip the wait and call customer care to ask.

6. Can a family member request this change on my behalf? 

No. It has to come from you directly. Your ID and signature are both required.

7. What happens if I never update my number after losing my SIM? 

OTPs and transaction alerts might keep going to the old number. This can be quite a problem in case there is some suspicious activity on your account, and you do not receive any alerts.

8. Are there any limitations concerning the frequency of changes of the number?

No published limit. But changing it too often, too fast, might get the branch asking more questions.

9. Do NRIs follow a different process for this? 

The branch process applies to NRIs as well, though some branches ask for extra documentation. Calling ahead to confirm what your branch needs is a good idea.

10. Can I download and fill the form before visiting the branch? 

Yes. The Data Updation Form (Annexure III) is available as a PDF on Union Bank's website, so you can print it, fill it out at home, and bring it already completed.
