If the common name needs to be changed, the only way to do so is by cancelling and reordering the certificate.
There are a few reasons why this might be the case. First, verify what email address you have chosen for the Doman Control Validation email (please note: this is different from the contact information provided during the generation process). If you need to change your DCV email, you can use any email on the Whois registration for that domain or one of the five following pre-approved alias email: Admin@domain.com Administrator@domain.com Hostmaster@domain.com Postmaster@domain.com Webmaster@domain.com Also, make sure to check the Spam or Junk Mail folder of your email provider.
There are two different types of validation procedures, those types being a certificate for an individual or an organization. If you apply under an organization name, please refer to the OV requirements mentioned above. If you apply as an individual developer, the Certificate Authority (CA) will require you to complete a simple form to verify your identity. This form has to be notarized by a lawyer, CPA, or public notary and you also need to provide a scan of a government issued ID and may be required to provide additional documents depending on the CA.
EV certificates require a more stringent verification process than OV certificates. To understand the basis of this procedure, please refer to the above question about OV certificate verification. Please note that EV certificates require you to complete a few extra steps, including proving both physical and operational existence as well as completing a simple telephone call with the Certificate Authority (CA) directly.
Organization Validated (OV) verification requires checking your business registration. If the Certificate Authority (CA) can verify this information using online government databases, no additional documents will be required. However, if the online filings are not available or inaccurate or not up to date, the CA may request additional official government registration documents, which vary on a case-by-case basis. A Dun & Bradstreet listing can usually satisfy most of the requirements for an OV certificate.
You do not need to provide any documentation in order to purchase a Domain Validated (DV) certificate. All you will need to do is confirm that you own the domain you wish to cover, either through a simple email or file-based authentication.
You can switch your method of Domain Control validation from file-based to email-based for any SSL product that we provide. You can switch from email-based to file-based only for Comodo products.
If you are unsure what your Control Panel/Server OS is, we recommend that you ask your web hosting provider or your IT department.
If you’re in a pinch and need your certificate fast, feel free to contact your SSL provider with the exact order you need expedited. They have connections with the Certificate Authorities (CAs) directly and can help make sure your urgent order is treated with top priority.
Your private key should always remain private. The only person that should see your private key is your hosting company, if they ask for it. However, do not delete your private key, as it is required for your certificate to work.
