# Phone Number Verification ## Why do I need to provide my phone number to register? When you sign up for GovTribe, we do require a phone number to deter fraud and maintain the security of the platform. We also use your phone number to help secure your account, and prevent unauthorized access. ## Landline? VoIP? Google Voice? We do not support use of landlines, VoIP providers, or Google Voice. GovTribe is only able to complete account verification via mobile phone numbers, and through a SMS text message. We do not support verification via email or via phone where the phone number is associated with a landline or VoIP provider. ## Supported Countries GovTribe currently accepts new account registration (and phone number verification requests) from these countries: * Australia * Canada * United Kingdom * United States --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
