Which address is used to send my User ID and Activation code?

The Government Gateway uses the postal address registered on the government department's system for the service you are enrolling to send you confirmation of your User ID and your service Activation code (if required).

After the Gateway has sent this information, your address is deleted from the Government Gateway. 

Please note: some services, including those operated by HMRC, do not offer postal confirmation of user IDs.

If you believe an incorrect postal address is being used for yourself contact the government department that runs the service you are enrolling for.  Contact details can be found from the link below.
