Your details

The more details you can give when you write to us, the more quickly we can deal with your request:

  • Your personal details: name; address; date of birth. If you haven’t told us about a house move or a change in your marital status or name, please also include your previous name and address.
  • Your reference numbers. Any or all of these: your NS&I number; holder’s or customer number; account number; Bond numbers; or Certificate numbers, if you know them. You’ll find these numbers on your Bond records, certificates of investment or any other letters from us.
  • Details of your accounts or investments: type of investment (eg Premium Bonds); approximate start date; and amount, if you know them.
  • Don't forget to sign your letter. For your security, we can’t disclose or change personal information without the account holder’s signature(s). If the investment was made for you when you were a child, we might not have your signature on our records. In that case, your signature should be witnessed by one of your parents (or another adult if your parent can’t sign) so we can transfer control of any investments to you.
  • If you are 16 or over and the investment was made for you when you were a child, we might not have your signature on our records. In that case, your signature should be witnessed by one of your parents (or another adult if your parent can’t sign).
