Numbers that Cannot Be Activated for WhatsApp on Twilio

Due to limitations of certain numbers and WhatsApp's ability to verify these numbers, there are certain specific number types that currently have mixed success rates when activating for WhatsApp on Twilio.

  • Argentina local numbers
  • Denmark mobile numbers
  • Netherlands mobile numbers

  • Singapore national numbers (voice-only)

If you wish to activate these number types, please note that success rates are mixed. If your goal is to complete onboarding for WhatsApp on Twilio as quickly as possible, we would recommend using a different number type to avoid any possible delays.
