When you purchase a digital certificate, the Certificate Authority (CA) that’s issuing it will put your website or organization through a process called validation.

Domain Validation (DV) SSL:This is the most basic type of SSL validation and can be completed in one step. It’s being issued within minutes.
Organization Validation (OV) SSL:CA validates the organization before issuing an OV SSL. They are the best for medium businesses where a click on the padlock indicates their company name. It’s being issued within 1 – 3 days.
Extended Validation (EV) SSL:EV certificates display trust at the topmost level, thus, large enterprises and corporations usually prefer EV SSL. The rigorous CA validation process before issuance of an EV SSL. It’s being issued within 1 – 2 weeks.
