The phone number connected to your bank account is what you typically use to make USSD transactions and receive debit or credit alerts. Given the attachment of your mobile to your bank account, it’s very dangerous to misplace it without instantly changing it from your Union Bank account.

Unfortunately, Union Bank doesn’t make the process of changing your phone number very accessible to all. If you’re willing to do it, there are specific steps that you must follow to effect the change to your new phone number.

In this article, I’ll show you how to change Union Bank phone number without much hassle.

How to Change Union Bank Phone Number

There are two ways to change the phone number that’s connected to your Union Bank account: you can either choose to do it from your bank or through an ATM outlet. Predictably, changing your phone number through the bank is quicker than doing it from an ATM, since there are verification issues that may delay the latter.

With that said, here are the two main ways to change your phone number at a Union Bank outlet using the two different ways mentioned above.

How to Change Union Bank Phone Number at an ATM

If you still have access to your debit card, you can visit any Union Bank ATM outlet to change your phone number. While you can easily withdraw from an out-of-network ATM, you’ll likely find no option to change your mobile number when trying to do it from an ATM that isn’t that of Union Bank.

When you find a working Union Bank ATM outlet, insert your debit card into the slot and enter your PIN to bring up the list of banking options. From there, select Services and then “Update or Change Mobile Number.”

After doing that, you’ll be asked to enter your new phone number to replace the lost one. You should see a status report after a few seconds letting you know if the process was successful or unsuccessful.

Note that you cannot start using the phone number immediately after changing it at an ATM. You must wait for Union Bank to update it on their end, and the process usually takes 24 to 48 hours. To be on the safe side, wait for two days before attempting to use the new phone number with your Union Bank account.

How to Change Union Bank Phone Number at a Bank Branch

While an ATM outlet is the easiest way to change your Union Bank phone number, it’s far from being the only way. If you want the update to reflect as quickly as possible, it might be better to use the Union Bank branch nearest to you.

On getting there, request to change the phone number connected to your Union Bank account. In response, the bank should give you forms to fill out to update your phone number. Before going for the update, however, it’s crucial to bring some documents along for identity verification.

Here are some examples of what you may need to change your primary phone number at any Union Bank branch.

  • A valid government-issued identification. For example, the national passport, national identification number slip, driver’s license, voter’s card, etc.
  • Your Union Bank account number.
  • Your full name as it appears on your bank account (tip: check your debit card).

Apart from the ones mentioned above, the bank shouldn’t require you to provide anything you won’t have or know on the spot. After submitting your application, the phone number change shouldn’t take over 24 hours, which is considerably shorter than changing it at an ATM (but significantly more stressful).


If you’re a Union Bank user, the chances are high that you’ll need to change your phone number someday. Reading this article today shows that you’ve reached a situation where you have to change your number, and as usual, I’m here to help.

In this article, I’ve explained how to change Union Bank phone number in two different ways. You can either choose to use the ATM option or the bank branch option and what you choose depends on your preference between simplicity and speed.
