Authentication for new certificates could take as little as 1 hour or up to several days, depending on the verification information you provide and whether or not your certificates are pre-approved.
Symantec can authenticate your organizational and contact information and store the information's pre-approved status for future certificate requests when you purchase units using a Symantec Certificate Center Enterprise Account.
When you submit a certificate request that contains the authenticated information, Symantec needs only to verify the domain. If your organization is the legal holder of the domain, you can expect to receive your certificate within 1 hour of your request. Processing times for Extended Validation SSL Certificates may take longer due to additional verification requirements mandated by the Extended Validation (EV) SSL Guidelines.
