This largely depends on the type of certificate that you purchased and your response times. No matter which type of certificate that you purchase, the Certificate Authority (CA) will be contacting you directly and will only proceed with next steps upon your response. For Domain Validated (DV) certificates, these can typically be issued in a matter of minutes to one business day. For Organization Validated (OV) certificates, these tend to take around 2-3 business days to be issued. And for Extended Validation (EV) certificates, these usually take between 3-5 business days to be issued.
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.
