Prize checker terms of use

In a nutshell these are

  • To use this app you must enter a valid Premium Bonds holder’s number or NS&I number. If you enter another person’s number on their behalf, you must have their permission.
  • If you want the app to remember and store a number, you must enter a name for each one.
  • You have the option to set up a PIN to make the app more secure. If your device is used by someone else (with or without your permission) and you have not set up a PIN, they will be able to see any information shown by the app, including the value of any prizes.
  • Full terms of use

    By using this application (“app”), you accept these terms of use.

    This app is intended to be used in, and by the residents of, the UK, the Channel Islands and the Isle of Man only. If you use this app in any other manner, you must make sure that such use is permitted by local law and any other law that may apply to you.

    NS&I will not charge you for this app, but your network provider may charge you for any data you may use in downloading and accessing it. If you use this app outside the UK, remember that your network provider’s data charges may be higher.

    This app can be used through entering either a Premium Bonds holder’s number or an NS&I number. It allows you to store your number and/or other people’s numbers. For a child’s holding, only their Premium Bonds holder’s number can be used. If you choose to store a number belonging to someone else, you must have their permission or permission from the nominated parent/guardian in respect of a child’s holding.

    You will be required to enter a name within the parameters permitted, for each Premium Bond holder’s number or NS&I number you choose to store. The app will display the name with the number being partially obscured.


    The app offers the option to set up a five digit PIN to help you keep your information more secure. If you set up a PIN and your own device also has Touch ID or Fingerprint enabled, the app will detect it and give you the option to use this.

    The app will allow a limited number of attempts to enter the PIN correctly before you will be locked out of using the app for a limited period of time.

    If you forget the PIN you will need to clear all data from the app and begin the process of storing your NS&I or Premium Bonds holder’s number(s) again.

    Remember that if you choose to store other people’s numbers and your device is used by someone else (with or without your permission) and you choose not to set up a PIN for the app, they will be able to see any information shown in the app, including the value of any prizes.


    NS&I will endeavour to ensure that this app works as specified on compatible devices and that the information provided is accurate. Provided we have exercised reasonable care, NS&I will not be liable for any loss or damage which may be suffered as a result of your use of this app, including (but not limited to):

    • any personal information that you choose to store on your mobile device using the app (such as your or someone else’s Premium Bonds holder’s number or NS&I number) becoming available to a third party if the device is lost, stolen or compromised;
    • any failure of, or temporary interruption in the availability of, the app.

    You must not download the app from anywhere other than the App Store or Google Play store or install or use it on a jailbroken (iOS) or rooted (Android) device.


    Obtaining unauthorised access to, or modifying, this app may constitute an offence under the Computer Misuse Act 1990. It is unlawful to cause damage to it intentionally or to any NS&I electronic facility or data through the knowing transmission of any program, information, code or command.

    When you use the app, we collect information about how you use it, for example which areas you use most often and if any technical errors occur. This is to help us resolve any issues and make improvements to the app. We will not be able to identify you from this information.
