Why did my PIN code get sent from a phone number?

Question

  • Why did my PIN code get sent from a phone number?
  • Why are long codes used on the 2FA short code API?

Answer

Some carriers have strict restrictions on the use of short codes. We are seeing better conversions when using long codes on those carriers. As a result, we use a combination of short codes and long codes (i.e. a LVN (long virtual number)) routes on our 2FA short code API to maximise delivery.

When a LVN route is being used, Acceptd/Not Applicable delivery status will be shown.
