# How long are the numbers active?

Usually, you will have up to 20 minutes after requesting a number to verify your selected service. 

It may even vary in the 5-10 minutes range in some limited cases. 

If you don't receive a code in that amount of time, the verification will timeout. 

If no SMS message is received - the payment is canceled. 

You always pay for successful activations only.
