Validation Requirements: The Core Difference

The fundamental distinction between certificate types lies in their validation requirements. DV certificates require only proof of domain control, which can be demonstrated through automated methods like email verification, DNS records, or file uploads. This process typically completes in minutes without human intervention, making DV certificates incredibly accessible but limited in the trust they convey. The automation enables free certificates and rapid deployment but provides no information about who actually operates the website.

OV certificates add organizational validation to domain verification, requiring Certificate Authorities to verify the legal existence and physical address of the business. This process involves checking government databases, business registrations, and conducting verification phone calls. The human element in OV validation typically extends the issuance time to 1-3 business days but provides users with verified information about the organization behind the website. This middle ground balances accessibility with enhanced trust.

EV certificates take validation to the extreme, requiring extensive verification of legal, physical, and operational existence. Beyond OV requirements, EV validation includes verifying operational history, confirming the specific individual requesting the certificate, and conducting rigorous checks through multiple independent sources. This process can take 1-2 weeks and requires substantial documentation, but it provides the highest level of assurance about the organization's identity and legitimacy.
