Note for Macintosh users: Although you can access the Government Gateway website with these browsers, Chamber SimplySign, Chambersign, Equifax and BT Trust Services digital certificates are not supported on the Macintosh. Macintosh users can currently only register for government services that require a User ID and password, not services that require a digital certificate (such as the HMCE New Export System or DEFRA IACS Area Aid Application).
When you enrol to use an online government service, you need to enter information that identifies your organisation (for example, your VAT registration number). Before you start the registration process, make sure you have available any documents or correspondence that contains the information you need.
