How to block your Jaiz Bank account

Cyber fraud, phishing links, stolen phones, and leaked banking details are now common threats to bank customers. If you suspect someone has access to your Jaiz Bank account, do not wait for confirmation before acting. Blocking the account immediately can prevent additional losses. Below are ways of blocking your Jaiz Bank account.

Use the Jaiz Bank USSD emergency blocking code

Jaiz Bank provides a quick USSD option for emergency account blocking. The USSD code can be used on both smartphones and feature phones and does not require internet access. Furthermore, you can use the code on another phone if your phone is stolen. Here is how to block your Jaiz Bank account using USSD code.

1. Dial *773*911*PhoneNumber#. Ensure you put the phone number linked to your Jaiz Bank account.
2. Follow the prompts on your screen.
3. Select the account you want to block.
4. Enter your USSD PIN, mobile banking PIN, or token details if requested.
5. Confirm the blocking request.

Once successful, a Post No Debit (PND) restriction is placed on the account to stop outgoing transactions.

Contact Jaiz Bank customer care immediately

If the USSD method fails or you cannot remember your banking PIN, contact customer support immediately and explain that your account may have been compromised and request an urgent debit restriction. You can contact Jaiz Bank customer support on 07007730000.

To secure your bank account, request the bank to temporarily disable transactions on mobile banking, internet banking, ATM card usage, and USSD transactions. Be prepared to provide the following details:

• Your full name.
• Registered mobile number.
• Account number.
• Recent transaction details.
• Identification details for verification.

Use the Jaiz Mobile Plus app

Jaiz Bank customers can also use the Jaiz Mobile Plus app to secure their accounts whenever they notice suspicious activity or unauthorised transactions. The app allows users to manage their accounts, cards, and security settings conveniently from their smartphones. To block your Jaiz Bank account through the mobile app, follow these steps:

1. Open the Jaiz Mobile Plus app on your phone.
2. Log in using your username and password.
3. Navigate to the Cards, Security, or Account Settings section.
4. Select options such as Block Card, Freeze Account, or Disable Transactions.
5. Choose the account or debit card you want to block.
6. Confirm the request using your PIN, OTP, or biometric verification.

Once the block is successful, your account or card transactions will be temporarily restricted until you reactivate the account through Jaiz Bank customer support or at a bank branch.

Visit the nearest Jaiz Bank branch

In some cases, you may need to visit a nearby Jaiz Bank branch for assistance. This is especially important if other bank account blocking methods have failed or one of the following events has happened.

• Fraudulent transfers have already occurred.
• Your SIM card was hijacked.
• Your online banking password was changed.
• Your ATM card was stolen.
• Your account remains inaccessible after blocking.

Jaiz Bank staff can place additional restrictions on the account and guide you through the recovery process.

How to secure your Jaiz Bank account afterwards

Blocking the account is only the first step if your Jaiz Bank account has been compromised. After the immediate threat has been stopped, you need to secure and restore your banking access properly. Below are some of the actions you should take to secure your bank account and recover it.

Replace your SIM card if necessary

If your phone or SIM was stolen, visit your mobile network provider first. Fraudsters sometimes use stolen SIM cards to intercept banking OTPs and alerts. Recovering your phone number before reactivating mobile banking helps reduce the risk of another attack.

Reset all banking credentials

After regaining access to the account, change all your banking credentials. Ensure you use the official bank procedures to change the following details:

• USSD PIN
• Mobile banking password
• Internet banking password
• ATM PIN
• Email password linked to the account

Avoid using birthdays, repeated digits, or simple combinations.

Review recent transactions carefully

Always check your transaction history thoroughly to identify and report any suspicious activities. Early reporting improves the chances of investigation and possible recovery. Look for:

• Unauthorised transfers
• Airtime purchases you did not make
• Unknown beneficiaries
• Failed login attempts
• Suspicious card withdrawals

Secure your phone and email accounts

Many banking compromises begin with hacked phones or email accounts. Security researchers have repeatedly warned about phishing apps, fake banking links, and malicious mobile software targeting banking users. To improve security:

• Enable screen lock and biometric protection.
• Avoid downloading APK files from unknown sources.
• Never share OTPs or banking PINs.
• Ignore suspicious SMS links.
• Enable two-factor authentication on email accounts.
