Several years old. Contact the number directly.
Communications and Telephone Systems issued these blocks several years ago. Customers swap carriers every few years, so Communications and Telephone Systems probably no longer holds them. Try calling any number you're interested in. If a person answers, you've found the current owner and can negotiate with them.

A long shot: if you'd like a watch in case we ever gain access to Communications and Telephone Systems's inventory directly, you can register your interest. We don't currently have visibility into number changes within carriers, so don't count on it.
