In order to create a Sideline account, you will need to provide a mobile number to use as your registered number. However, there are some restrictions by city and/or location which you should be aware of.
As a general rule of thumb, any valid carrier phone number from the contiguous United States is accepted for creating an account.
What isn't considered part of the contiguous United States, and thus not accepted for registration:
- Hawaii (HI)
- Alaska (AK)
- American Samoa (AS)
- U.S Virgin Islands (VI)
- Northern Mariana Islands (MP)
- Guam (GU)
Important: Any of the locations/area codes mentioned above are not approved for use with Sideline and thus will be unable to create an account.
Additionally, if you change the number that is registered with your Sideline account to any of the above locations, Sideline will no longer work for you as we do not support numbers located outside of the contiguous United States.
We are sorry for any inconvenience that this may cause. If you have further questions or concerns, please submit a request.
