The time it takes for issuance varies on the type of SSL Certificate purchased.
Domain Validation
This type of validation typically takes about two business days once approved by the owner. Domain Validation is the process in which the Certificate Authority (CA) contacts an administrator of the domain to make them aware of and approve the request.
Organization Validation
Organization Validations may take up to 3 business days once the owner has approved the request. This validation type requires the verification of domain ownership as well as the organization’s information included in the certificate, (name, city, state, and country).
Extended Validation
An Extended Validation Certificate (commonly referred as EV), may take up to 10 business day to be issued after the owner has approved the request. In these certificates, the domain, and organization information are verified as well as the company’s legal existence.
