How to Block Access Bank Account
Have you ever found yourself in a situation where your phone or ATM card was stolen and you needed to act fast to secure your bank account? You’re not alone. With digital banking becoming more widespread, the need to understand how to protect your finances in emergencies has never been more important. Whether you’re in Nigeria or abroad, knowing how to block your Access Bank account quickly can save you from financial loss and emotional stress.
This guide is designed to walk you through every method available—USSD codes, mobile apps, customer care, and even steps to take if you no longer have your SIM card or device.
How to Block Access Bank Account
If you’re worried that someone may gain unauthorized access to your Access Bank account, there are several reliable ways to block or restrict it immediately. You don’t need to be tech-savvy, and you certainly don’t need to panic. Below are all the major options available in 2025.
1. Using the USSD Code: The Fastest Method
This is your best bet if you’ve lost your phone or suspect unauthorized access.
Dial *901*911# from any mobile phone (not necessarily your registered line).
- Follow the prompt.
- Enter the phone number linked to your Access Bank account.
- Confirm and block the account immediately.
This method works without an ATM card, and even if you’re using another phone number or device, it still secures your account instantly.
Note: This method is often referred to as the Access Bank account blocking code, and it’s functional across all networks in Nigeria.
2. Via the Access Bank Mobile App
If your phone is still in your possession but you suspect suspicious activity:
- Open your Access Bank mobile banking app.
- Go to the “Self-Service” or “Security” section.
- Select “Block Account” or “Restrict Account.”
- Follow the prompts to confirm the action.
This works even if you’re outside Nigeria, as long as you’re connected to the internet.
3. Calling Access Bank Customer Care
If you can speak with a representative, this is a very effective route.
Call Access Bank customer care number:
+234 1 271 2005 or 07003000000 (Available 24/7)
Provide your account details and request an account freeze. Be ready to confirm your identity with:
- Account number
- Full name
- Last transaction details
You can also block specific features like your ATM card or USSD transfer access through this channel.
4. Blocking Access Bank Account from Another Phone
If your registered SIM is stolen or lost, you can:
- Dial 901*911# on any mobile phone.
- Or call Access Bank customer care from a friend’s or family member’s phone.
- You can also reach out via social media handles (e.g., Twitter) or email.
This is especially useful if you’re wondering how to block your Access Bank account from another phone or phone number.
5. Using the ATM Option
Though less common for blocking accounts, some ATMs have self-service menus where you can:
- Temporarily block your ATM or debit card.
- Report a card as lost or stolen.
But this only works if you still have your card and need to disable features without blocking the entire account.
How to Block Access Bank ATM Card (Only)
If you’re only concerned about someone using your debit card:
USSD Method
Dial *901*11#, select “Other Services” > “Card Services” > “Block Card.”
Online Method
Log in to your Access Bank app or internet banking portal and navigate to Card Services, then choose Block Card.
If Card is Lost or Stolen
You can use this method to block just the card while retaining access to your account via other channels.
How to Block Access Bank USSD Code or Transfer Feature
If you suspect that someone might try to use USSD to move money from your account:
- Dial 901*911# and follow the prompts to block USSD access.
- Alternatively, call customer care and request USSD deactivation only.
- This allows you to keep your ATM and online banking functional while cutting off mobile transfers.
How to Block Access Bank Account Without ATM Card or SIM Card
This is one of the most common concerns. Fortunately, there are workarounds:
Option A: USSD from any phone
Use the emergency blocking code 901*911#.
Option B: Email Customer Support
Send a formal request with your account details to the Access Bank customer care email: [email protected]
Option C: Walk into any Access Bank branch (if you are near one) with a valid ID and request that the account be restricted.
Tips for Staying Protected
To avoid future financial scares:
- Activate transaction alerts via email and SMS.
- Regularly update your banking passwords and PINs.
- Do not share sensitive banking information on phone calls or online.
- Enable fingerprint or face recognition on your Access Bank mobile app.
You never know when you’ll need to act fast to protect your money. Whether you’re dealing with a stolen phone, suspicious activity, or you just want to block your Access Bank account for safety, knowing the right steps gives you control and peace of mind.
I recommend that you save the USSD blocking code (*901*911#) and Access Bank customer care number somewhere you can easily access—even if your phone goes missing.
If you’re ever unsure, call Access Bank support directly or visit your nearest branch. You don’t need to panic. Just take action.
