Hi @Del-brk!
I can definitely help you out with that! Short codes are pretty cool to use if you know what companies they’re associated with, and like you mentioned, if they are indeed real ones or not.
Short Codes allow you to send text and multimedia messages from your phone using shortened phone numbers. You are able to send text messages to short codes to access a wide variety of content, for example voting for a favorite TV show contestant, retrieving trivia, checking weather forecasts, or ordering ringtones and other AT&T and third-party services.
To confirm and learn more about Short Codes and what the numbers represent by clicking here.
Hope this helps! Take care and feel free to reach back out of you have any other questions! Have a wonderful week!
Tim, AT&T Community Specialist
