How to Block UBA Account from Another Phone | Full Guide

If you’re using United Bank for Africa (UBA) and your phone gets lost or stolen in Nigeria, it’s important to block your UBA account from another phone right away.

Just like other banks, UBA allows you to use digital banking, which means you can access your account and perform transactions using your phone or computer. You can pay bills, send money to other banks, and check your account balance—all without going to a physical branch.

While this is very convenient, it also comes with some risks. If someone else gets access to your phone or banking details, they might try to steal your money. That’s why it’s important to act fast when your phone is missing or when you think someone is trying to hack your account.

Blocking your UBA account quickly can protect your money and stop any unauthorized transactions. In this article, you’ll learn the simple steps to block your UBA account using another phone via mobile app, sms, USSD code, or online, especially in cases of theft, loss, or suspected fraud.

Why You Should Block Your UBA Account

Blocking your UBA account or ATM card can protect you from losing your money and going through unnecessary stress. There are several situations where knowing how to block your account quickly from another phone can help keep your funds safe.

One common reason is when your phone gets lost or stolen. If someone else finds your phone and has access to your UBA account through the mobile app or USSD, they might try to steal your money.

Some can even borrow money from your UBA bank app online. But once you block your account, no one will be able to make any transactions from it.

Another reason to block your account is if you feel like someone else might know your account information—for example if you notice strange activities or receive suspicious messages. Blocking your account in this case helps prevent fraud before it happens.

Also, if you misplace your ATM debit card, it’s a smart move to block it immediately. This prevents anyone who finds the card from using it to withdraw your money from an ATM or make purchases.

Can a Scammer Block Your Bank Account?

Yes, a scammer can block your bank account if they can access your private banking details. For example, if someone knows your UBA account number, phone number, and USSD PIN, they can access your account, take your money, and even block the account.

That’s why you should never share your banking information with anyone you don’t trust.

Always keep your bank details safe. This includes your:

• USSD PIN
• ATM card number
• ATM card expiry date
• CVV (3-digit number at the back of your card)
• ATM PIN
• Token codes
• Online banking password

If any of these details fall into the wrong hands, you could lose your money to fraud.

Also, UBA will never ask you for your PIN or password, so don’t give it to anyone pretending to be from the bank.

What Options Do You Have to Block Your UBA Account from Another Phone?

UBA understands that security is very important to customers. That’s why they offer different ways for you to block your ATM card and account easily, depending on what you can access at the moment.

In situations where you need to block your UBA account from another phone, there are several method options to pick from.

Here are the different ways you can block your UBA account or card from another phone:

#1. Mobile Banking App

UBA has a simple mobile app that you can download to your smartphone or tablet. With just a few taps, you can block your ATM card or account anytime and anywhere, as long as you have internet access. 

In case your phone is stolen or can’t get hold of it, you can still make use of the mobile banking app on another person’s phone to block your UBA account.

#2. USSD Code

There are UBA USSD codes for airtime, transfer, and mobile banking. Likewise, there is a USSD code for account blocking too.

If you don’t have internet access, you can still block your account using a special USSD code from the phone number linked to your UBA account. This is very helpful when you’re in a place with poor internet or using a basic phone. 

#3. UBA Self-Service Platform

With another phone, you can go online and use UBA’s self-service website to manage or block your account. This includes options like blocking your card, checking your balance, or requesting a new card—all from the comfort of your home or office.

#4. Customer Service Hotline

If you prefer to talk to someone directly, UBA has a customer care number you can call. This is another way to go about blocking your UBA account from another phone. While you may need to wait a little on the line, a representative will help you block your card or account and guide you on what steps to take next.

#5. Visit a UBA Branch

If you’re not comfortable using another phone or the internet, you can always walk into the nearest UBA branch and ask for help. The staff there will help you block your ATM card or account and also give you advice on how to secure your banking details in the future.

How to Block Your UBA Account Using Another Phone Via USSD Code

If your phone gets lost or stolen, it’s important to act fast to protect your money. UBA has made it easy for you to block your account using any other phone, even if it’s not the one linked to your bank account. You don’t need internet—just follow a few steps using a USSD code.

Here’s how to do it in four simple steps:

Step 1: Dial *919*9# on Any Phone

First, borrow any phone—maybe from a friend or family member—and make sure it’s using a Nigerian network like MTN, Airtel, Glo, or 9mobile. Then dial *919*9#.

This special USSD code is used to start the process of blocking your UBA account.

Make sure the phone you’re using has a strong network signal so the process won’t fail.

Step 2: Type in the Phone Number Linked to Your UBA Account

After dialing the code, the system will ask you to enter the phone number you used to open your UBA account.

This helps UBA know exactly which account you want to block. Type in your correct phone number, and make sure there are no mistakes.

Step 3: Enter Your 4-digit USSD PIN

Next, you’ll be asked to enter your 4-digit USSD PIN. This is the PIN you normally use to perform transactions through UBA’s USSD service.

It’s a security step to confirm that you are the real owner of the account. Enter the correct PIN carefully—if you enter the wrong one, the process may not go through.

Step 4: Wait for a Confirmation SMS

Once you’ve entered your details correctly, UBA will send a confirmation text message (SMS) to let you know that your account has been successfully blocked.

If you don’t get the confirmation message after a few minutes, it’s a good idea to call UBA’s customer care to double-check if your account has been blocked.

• You can’t send or receive money
• You’re no longer a UBA account holder
