Authy virtual numbers for SMS verification

Picking the right country for Authy

An Authy number is in stock in 10 countries right now, 677K lines in total, and the entry price is $0.08 in United Kingdom. The price gap between countries is not arbitrary: it follows what the local networks charge and how often they actually deliver, which is why the table above shows both next to each other.

Every line here is a real mobile number on a real operator, not a VoIP or relay range. That distinction decides more sign-ups than price does: platforms look a number up in the carrier databases before they send anything, and a line type that comes back as internet-provisioned is refused before an SMS is ever attempted. It is also why this catalogue is smaller than it could be.

The reason most people take a number for Authy is not that they lack one. It is that a personal line attached to an account is a permanent link between the two, and there is no way to undo it later. A one-time line covers the verification step and disappears, which leaves the account without that link.
