Hey everyone sorry for the noob question, I was getting different answers on Google.

My question specifically is: Am I able to purchase a EV SSL for each of my sub-domains.

Thanks in advance.

    No wildcards, but there's no reason you couldn't buy one for each subdomain individually. – ceejayoz Dec 17 '17 at 14:48

    No, but it looks cool. – user3724476 Dec 17 '17 at 15:10

    I guess if you don't mind paying 2, 3, 4 times the price for "looking cool". – joeqwerty Dec 17 '17 at 15:14

Note that they must be Subject Alternative Name (SAN) and wildcards are not allowed.

9.2.2. Subject Alternative Name Extension

Certificate field: subjectAltName:dNSName

Required/Optional: Required

Contents: This extension MUST contain one or more host Domain Name(s) owned or controlled by the Subject and to be associated with the Subject’s server. Such server MAY be owned and operated by the Subject or another entity (e.g., a hosting service). Wildcard certificates are not allowed for EV Certificates.
