I’ve checked and I can’t move my land line to Google Voice – “we don’t work with that provider”. It’s currently with Verizon FIOS. It used to be a regular land line number, then Vonage, and now part of a triple play.
What if I moved my land line number to a cell phone line first? Could I then move it to Google Voice?
Rather than porting it to a cell phone, you might take a look at Number Barn. I’ve used them to park a number I wan’t quite ready to transfer to a new line, and it worked just fine.
This method of moving your land line / voip number to a cell phone and then to Google voice does not work for some numbers. I have been there and gone through the landline to mobile transfer just to realize that Google still won’t transfer the number
Use this google website if your number can be ported. If it gives a message like “Ooops! This number appears to be from an area we don’t currently support.” - then it is unlikely that porting to a mobile first will work.
