I am writing to report an issue I am experiencing while attempting to create users with phone numbers in E.164 format from countries like Belgium and Ireland. When I try to create a user with a phone number in E.164 format, I receive an error message that prevents the user from being created.

Belgium number : +3227933835

"message": "TOO_SHORT"
}
```
