If you don't want your number to be searchable in the GetContact app, first choose your country then enter your phone number below, and press "Unlist" button. (example: +12371234444).
If you are a GetContact user and have verified your number you must first Remove your account by going to the Settings menu in the app. Select the Settings tab > About GetContact > Account Settings > Remove account.
Please note that it can take up to 72 hours before the number gets removed. Please note that when you start using the GetContact application again with the same number, it will be relisted.
