13224: Dial: Twilio does not support calling this number or the number is invalid


ERROR: 13224

error-13224 page anchor
ERROR

This error occurs when a <Dial> request targets a destination that Twilio cannot route or that is not a valid callable phone number. Format destination numbers in E.164 and verify that the destination is valid and in service before you place the call.

Possible causes

possible-causes page anchor
  • The destination number is not formatted in E.164, such as a missing + or country code.
  • The destination uses a country code, area code, or exchange that does not exist or is not assigned.
  • The destination is a premium rate or shared-cost number that Twilio does not support for outbound calling.
  • The destination is formatted correctly, but no carrier partner can complete the call because of a local telecom network outage.
  • Send the destination number in E.164 format, for example +14155552671.
  • Check that the country code, area code, and subscriber number are valid for the destination you want to call.
  • Validate the number before you place the call. Use Twilio Lookup to confirm formatting and basic number validity.
  • Do not dial premium rate or shared-cost destinations.
  • If the number is valid and correctly formatted, try the call again later to rule out a temporary carrier outage.
