Im having the same issue with the exception of the last 4 digits. The othe day when I looked them up it said a hotel, now its saying unlisted through something like a internet box. Im guessing its a number someone can get unlisted through a internet service. I put a app on my phone to block the crazy numbers I dont want, it will block text messages and I have unlimited phone number look up. I love it. Good luck, if I come across who owns the number your looking for I will post it for you.
