Are overdraft text alerts secure?

Yes, they are secure. The text message will come through with the name ‘Co-optiveBk’ as the sender. We will only include the last four digits of your account number and we won’t include your name, your account balance, any embedded links or phone numbers within the message.

Make sure we have the correct mobile phone number registered for you by logging into online banking. Once you have logged in:

1. Select My details from the main menu.
2. Select Phone numbers.
3. Click on change next to the number you want to change.
4. Enter your number (your mobile number needs to be a UK mobile number).
5. Click Save.

You’ll need to enter your password, 6-digit security code and a verification code we will send to you. It's important that you never tell anyone your verification code. When changing your contact details in online banking, we will send a verification code to the contact details we currently have for you, not your updated details. Please allow one business day for your phone number to update.

You can also update your contact details using our mobile app. Log in, and:

1. Select More in the bottom right corner of your account view.
2. Select My settings and details.
3. Select Personal details.
4. Select Edit on the information you'd like to update.
5. Once updated, select Save.

We'll ask you to verify the change by using your fingerprint, passnumber, or facial recognition.

Please allow one business day for your phone number to be updated.

When we send a verification code in online banking, we’ll tell you in the message what the code is for. If you ever receive a code you were not expecting, or if the code is for a different transaction, contact us on 159.

If you are unable to receive a verification code, you can call us on +44 (0) 3457 212 212 to update your contact details. Lines are open 8am to 6pm Monday to Friday, 9am to 5pm Saturday and Sunday. Call charges
