What's on this page

Child accounts and FlexOne existing customers

If you're already a Nationwide customer and opening a child or FlexOne account, we'll write to you if we need to see proof of your name and address. You can do this by visiting your local branch.

Child accounts and FlexOne new customers

When you open a new child or FlexOne account we'll normally ask for:

  • proof of the child's name
  • proof of the child's address, or an adult's address if they live together
  • additional ID if an adult is named on the account.

Use the guidance in the sections below that applies to you.

Child only is named on the account

We'll need:

  • One document from the ‘Proof of child’s name’ table shown below.

AND

  • One document from the ‘Proof of address’ list in the table below if the child lives with an adult. The document can be in either the child’s name or the name of the adult they live with.

Child and adult are named on the account

We'll need:

  • One document from the ‘Proof of child’s name’ table shown below.

AND

  • One document from the ’Proof of current address’ where the child lives with the adult in the table shown below.

Use the guidance in the sections below for proof of child’s name and address.
