What is an OV S/MIME Certificate?

An OV S/MIME certificate verifies that an organization exists and has authorized the use of the certificate, then binds the organization's verified identity to a corporate email address. It's typically used for role or department mailboxes (support@, billing@, hr@) and corporate communications where the sender represents the business itself. Signed messages display the verified organization name so recipients know the email genuinely comes from your company.

Questions

Frequently asked questions

How is OV S/MIME different from IV?
IV verifies an individual person; OV verifies an organization. OV is the right choice for role mailboxes (support@, billing@) where the sender represents the company, not a specific person.
Can I use OV S/MIME on multiple addresses?
Many OV S/MIME products allow multiple authorized addresses on the same verified organization domain — check the specific product terms. For combined coverage, see Sponsor S/MIME.
How long does issuance take?
Typically 1–3 business days, including organization verification.
Will my company name show in recipients' clients?
When recipients inspect the signature, yes — the verified organization name from the certificate is shown.
Is encryption supported?
Yes — OV S/MIME supports both signing and end-to-end encryption with compatible recipients.
