What are the requirements for Extended Validation (EV)?

Extended Validation uses the same method as OV, just a much more thorough validation. The first step is signing a Subscriber Agreement and Certificate Request Form. These give some basic information for the CA to start the vetting process, as well as you agreeing to the terms. Once they have that, they do the business validation. That is followed by the domain control check. Finally, they initiate a manual callback to the number listed on your business database. They ask for a confirmation that you ordered the EV Certificate and approve it.
