NS&I releases some details about the Premium Bonds prize winners on the first working day of the month, and the prize checker will be updated the following day.

There are several ways to use the Premium Bonds prize checker – the NS&I website, prize checker app and the Amazon Alexa skill.

To use the prize checker on the NS&I website, savers will need their holder’s number.

This can be found on one’s Bond record or by logging into the account.

It will either have nine or 10 digits, or eight digits followed by a letter.

Savers can use their holder number or their NS&I number, which is 11 digits long, to check for prizes on the prize checker app.

Mobile users can download the Premium Bonds prize checker app on the Apple App Store or Google Play for Android devices.
