Error 13224

ERROR - 13224

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

Twilio does not support calling this number or the number is invalid

Possible Causes

This error occurs when the provided number is not in E.164 format; for example using local dialing pattern 01234567890 instead of the full E.164 address +441234567890. This can also occur when calls are attempted to non-existent country codes, area codes, or exchanges. For example, there is no +693 country code, no +1238 US area code, and no 555 US exchange.

This can also occur with properly-formatted, valid destinations if none of Twilio’s carrier partners are able to deliver the call; for example due to a telecom network outage in the phone number’s local area.

Possible Solutions

Use E.164 formatting and ensure the destination is a valid, in-service destination.
