How can I add SANs to an existing certificate?

Some certificates can be modified in order to add, modify or delete SANs from their SANs list during their lifetime.

What is the procedure?

To edit the list of SANs to secure, go to your certificate status page and click on "Request reissuance". If there is no such button it means the certificate cannot be reissued. In that case contact our sales team.

One your are on the reissuance form, edit the SANs list here:

WARNING: some certificates do not allow their main name to be modified.

Provide, if needed, a new CSR, enter the reason for the reissuance and click on "Process this request".

What about the price?

The reissuance is free. Only the additional SANs are invoiced. If additional SANs need to be purchased for the processing of your request then our sales team will contact you.

please note that a SAN has always the same validity period than the certificate on which it is attached. If you bought a certificate valid 2 years, you'll have to get SANs that are also valid 2 years no matter the time left before your certificate expiration (no prorata).

Are there suppliers specific features?

Yes. Each certification authority applies its own rules.

For example, it is not possible to modify a Certigna certificate. Once the certificate is issued, it is "frozen", its SANs list will remain the same. See the links below.

Are there several kind of SANs?

Yes. Several certification authority propose wildcard SANs (to secure site like * for example) or domain SANs. The system will automatically detect which kind of SAN you are trying to add to your certificate. If you request a wildcard SAN on a certificate that do not allow this kind of SAN you'll see an alert on the confirmation page.
