The Activation Token is a unique one-off security code provided at the point of pre-registration (displayed on screen or sent by post) for Pension Schemes Online. It will always start with 'PP' followed by nine numbers, which are automatically generated and always unique. This allows you to switch the service on quickly as soon as you complete the online service registration process. Once you have registered you will not need to enter it again so you can dispose of it. There is no time limit on when the Activation Token can be used.
