Why you need to verify your phone number
For personal campaigns in select countries, you may be required to verify your account by phone. Verifying your phone number before you withdraw allows an extra layer of protection whenever you are managing your funds. Relying on a password alone is less secure because a password is something that someone else may be able to obtain.
You will need to make sure that you use a phone number in the same country that you created the campaign in. For example, if you set up a campaign in the United States, you will need to have a code sent to a US phone number within the 50 states. If you set up a Canadian campaign, you will need to verify with a code sent to a Canadian phone number.
