How can we help?

We’re happy to answer any questions you may have.

What information do I need to check if I have won a prize?

You can use your holder's number or your NS&I number.

Using your holder’s number

You can use your holder's number on the prize checker on our website and in our prize checker app.

All your Premium Bonds are grouped under a unique holder’s number.

You can find your holder’s number on your Bond record or by logging into our online service. Your holder's number has either 10 or 9 digits, or 8 digits followed by a letter.

Or write to us and ask for a Bond record. This will show all the Bonds you hold as well as your holder's number and your NS&I number.

Using your NS&I number

You can only use your NS&I number to check if you have won a prize using our Premium Bonds prize checker app available on iOS or Android.

If you have an NS&I number, you'll find it on most communications you've had from us. It is 11 digits long and starts with an 11, 21, 31 or 41.

I only know my Bond number(s) or I have lost my documents

Sorry, you can’t use your Bond number(s) to check if you have won a prize. However you can write to us and ask for a Bond record. This will show all the Bonds you hold as well as your holder's number and your NS&I number.
