Have your details to hand

To manage your accounts or personal details, you'll need to be registered for our online and phone service. Please have your NS&I number and password to hand.

What is an NS&I number?

If you aren’t registered or don't have those details to hand, we may still be able to deal with your enquiry once we’ve asked you a few security questions.

Write to us at NS&I, Sunderland SR43 2SB

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 you are over 16 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 so we can transfer control of any investments to you. The witness must be aged 18 or over and must not be a member of your family. The witness must also sign the form.
