Several years old. Contact the number directly.
SunCom dba T-Mobile USA issued these blocks several years ago. Customers swap carriers every few years, so SunCom dba T-Mobile USA 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 SunCom dba T-Mobile USA'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.
