Verifying identities helps protect us all from fraud
- We carry out identification requirements to protect everyone from fraud
- Where possible, we will first use electronic searches to confirm your identity
All banks, building societies and financial institutions are required by law to verify the identity of any individual or organisation that opens an account with them. This is necessary to protect the organisation, its members and the public from fraud and also to help combat money laundering.
You should note that there may be occasions when documentation over and above that stated here will need to be produced and you will be told if this applies to you.
What we need to verify an individual's identity
Existing member - quote your account number on your application:
If you already have an account with us and quote your account number on your application, we may not need any further evidence of your identity and address.

Certification: The document that is being certified must state 'original seen' as well as being dated and signed.
