If you receive an error stating that your phone number is not associated with your unit, it usually means the number entered during registration does not match a phone number your guest is providing in attempting to register as a visitor.


This is most commonly caused by:

  • A typo when entering your phone number

  • Using a different number than the one originally registered

  • Attempting to register a guest using a number not linked to your account
