Trusted SSL certificates undergo a more rigorous verification process. This is because they provide a higher level of assurance to website visitors by displaying the organization's name in the address bar. The extended validation process for Trusted SSL certificates typically involves verifying the legal identity and existence of the organization, conducting thorough background checks, and validating the organization's domain ownership. These comprehensive checks and verifications require more time and documentation, resulting in a longer validation period, often taking up to 24 hours.

Commercial SSL certificates, such as Domain Validation (DV) and Organization Validation (OV) certificates, follow a less intensive validation process. DV certificates validate the domain ownership, while OV certificates additionally verify the organization's identity. The validation for Commercial SSL certificates can be completed more quickly, usually within an hour, as the process involves fewer verification steps and documentation requirements.
