What Is a UCC?

A Unified Communication Certificate (or UCC) is a digital security certificate which allows multiple hostnames to be protected by a single certificate.

UC certificates are also known as Subject Alternate Name (or SAN) certificates, multi-domain certificates or Exchange certificates.

All SSL.com UCCs:

  • CAN secure up to 2000 entries. (The first three non-wildcard entries are included, with an additional charge per entry after that.)
  • CAN be used on unlimited multiple servers concurrently.
  • CAN be reissued to change domains at any time without extra fees or costs.
  • CAN be used on unlimited IP addresses with multiple, concurrent private keys (which is great for hosting and virtual hosts).

Entries in any SSL.com UCC:

  • CAN be a Fully Qualified Domain Name (FQDN).
  • CAN be a wildcard domain name (i.e. *.domain.com or *.store.domain.com) but NOT a multiple-level wildcard (like *.*.domain.com).

Domain-validated SSL.com UCCs can be ordered for up to five years. UCCs with extended validation can be ordered for up to two years.
