Changing your business banking details

If you want to change business account details like your name, registered/correspondence address, phone number, email and iBusiness Banking information, we're here to help. Where and how you update your details depends on what you need to change and which AIB business product or service you use. 

Your iBusiness Banking (iBB) details are kept on different systems to your business account details and will need separate requests to change them. Updating your business account details does not automatically update iBB details (and vice versa) and separate requests are needed to ensure records remain accurate.

How to change your iBB details.

To change your business name, registered address and/or correspondence address you need to:

• Update your business name and/or registered address on the Companies Registration Office (CRO) before requesting the change on your AIB account. You don’t need to complete this if you’re only changing your correspondence address.

• Visit a branch to complete a Notification of change of name/address for companies/unincorporated entities form.

• Have the form signed by authorised signatories on the account, in line with your mandate, and return it to any branch by post or in person. 

To change your business email or phone number, you need to:

• Provide a written instruction to any branch or by post.

• Include your account number

• The instruction needs to be signed in line with the signing instruction on the account. Here’s more information on authorised signatories.
