Question
Why did my PIN code get sent from a phone number?
Applies To
- PIN Code
- Long Virtual Number
- Short Code
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 code and long code, that is, long virtual number (LVN), routes on our 2FA short code API to maximize delivery. When a LVN route is being used, Acceptd/Not Applicable delivery status will be shown.
