The number needs to be able to receive either SMS or Voice Call to get the PIN.
Even a LAND LINE will work.
If you are using an ipad or ipod, you can use any number to get the code and then enter it in on your device.
Btw, phone number verification ensures that every person you see on PHHHOTO is real. No spam, bots, creepers, or dupe/fake accounts!
Sorry, but we won't answer support requests to email the code. #sorryboutya
