How can I get a landline phone number without having a residence address?

If you don't have to have a specific number but a phone number with the area code and suffix combination for a region, that can be done quite easily. As a Hosted VoIP Service Provider, we are able to provide a local number for any region you specify. Once we provide a number for you in that region, we can forward all calls to another number, or you can plug in an IP Phone into your network and make inbound/outbound calls from it. If you need a specific number, you will need to own that number. Otherwise, no phone service provider will port that number to you. Hope this helps and feel free to contact me if there are any questions I can answer for you. My contact information can be found in the website referenced below.
