Resolution

If your mobile number has been incorrectly classified as a landline number, and you are able to confirm the number is a mobile number and the network it is on, submit a Support request so that we can assist you with this issue.

Cause

When using Verify you will not receive an SMS if your number is listed as a landline. Unfortunately the USA and Canada can be a very challenging area for identifying whether a number is a mobile or landline number, due to sharing the same prefixes. Due to this, many providers can classify a number incorrectly. Some landlines do have the ability to accept SMS, but the majority do not. Due to this, we will not attempt to send an SMS to this number and will proceed only with the Text-to-Speech (TTS) call which will provide the PIN to you.

Even if an SMS is not sent, a TTS call will still occur to the number providing the PIN to the user.
