title: Receiving SMS Messages from Short Code Numbers?
body: <p>Firstly I would appreciate if someone can tell me if such a service already exists because it would save me a ton of time. A lot of the topics here discuss sending, I am trying to receive.</p>
  
  <p>I am trying to design several web apps that interface with our vendors web portals to automate some daily tasks, while some of the vendors suggest or request MFA. A few vendors make it mandatory, so therefore I can't have my web app access the data behind the portal unless I can read the SMS message code that is being sent. While services like Twilio exist that allow me to receive SMS messages, they do not accept inbound messages from Short Code SMS. This appears to be true for a lot of providers. Google Voice is the only exception to this, but restricts me because I have to link an actual phone to my Google Voice account and I have to make a new account if I want more than 1 phone number. Not to mention I don't want to have random Google accounts not connected to a domain or organization.</p>
  
  <p>Is my only recourse here to build or buy an inhouse SMS Gateway with a bunch of sim cards for every number I need?</p>
