Certificates with organization validation are validated on company data, the company details are visible within the SSL certificate, therefore an organization validated certificate provides more trust to the visitors of a website. Visitors can verify the company behind the website.
Next, to the domain validation where the website owner needs to verify that they are in control over the domain name where the certificate is requested for, the company data is also being verified.
Via a public register such as the Chamber of commerce the company data is being verified and the organization is also called to verify the company.
The time of issuance for an organization validated certificate differs per supplier, due to a telephone verification and the validation of the company can take up between 1-3 working days.
