We recently added over 8,000 new SMS shortcodes (5-6 digit phone numbers) so you can receive notifications from more of your favorite airlines, banks, and social media sites.
Sideline also supports a variety of validation/verification codes which we get through our provider, SAP, which helps to verify ownership of an account with a forgot password (for example).
If you did not receive the text with a code, this most likely means it's not yet supported. We are sorry if this causes you any inconvenience.
Please note: This may be subject to change in the future, depending on the support of other services through our provider.
Check out our blog post for more information on shortcodes and the benefits.
