  1. I am trying to find out where this # is coming from, it’s 1-437-220-xxxx. I have been asked to called it. I live in St. Cloud, Mn. And on my landline phone, I can’t get anywhere. There’s also this # 1-403-471-xxxx, and I can’t get anywhere with it also. There is no 1-800#,to call, and no address,or e-mail given either.

  2. Both codes are Canadian (Ontario and Alberta provinces respectively). Make sure you are able to dial international calls from your home phone.
