Accounts for a child under 13 years old

To open an account for your child under 13 years old, you’ll need:

• ID and proof of address for yourself as the parent(s) or guardian(s). See ID requirements for valid documents you can bring. (If you’re the legal guardian of a child, you might need to supply additional documents as evidence of this.)
• Your child’s ID as per options 1 and 2. If using option 2, a non- photo form of ID can be used as a stand-alone document (i.e. your child can provide their birth certificate as a stand-alone ID document).
• Confirmation of your child’s address as per our address requirements. Your child can also use a letter from a registered medical practice or hospital as proof of address.
• If you’re unable to go into a store, you are able to use a trusted referee for ID certification.
