Several years old. Contact the number directly.

Ameritech Wisconsin issued these blocks several years ago. Customers swap carriers every few years, so Ameritech Wisconsin 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 Ameritech Wisconsin'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.
