Rediffmail virtual numbers for SMS verification

Buying a Rediffmail number, in practice

A Rediffmail number is in stock in 83 countries right now, 1.2M lines in total, and the entry price is $0.25 in India. 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.

One Rediffmail code and a Rediffmail number you keep are different purchases. A one-time line goes back to the network once the code is delivered, which is fine until the service asks again from a new device. If that is likely, the rental catalogue answers it; if it is not, paying per code from $0.25 is the cheaper of the two by a wide margin.

The reason most people take a number for Rediffmail 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.
