What is an Extended Validation (EV) SSL Certificate?

What’s the Difference Between DV, OV and EV?

Domain Validated (DV), Organization Validated (OV) and Extended Validation (EV) TLS/SSL certificates are differentiated by the level of identity checks they require and protect brands against. DV certificates require only web domain verification. OV certificates build upon DV certificates by validating a domain’s owner as well as organization type, name, status, phone number and organization blocklist check. EV certificates require the highest number of identity checks by involving all the same checks for DV and OV and adding validation of the organization’s registration number, jurisdiction, operational existence, domain fraud check and blocklist checks.
