Who I have the same questioned this topic

I just switched to Verizon from ATT.  I'm not getting short code SMS messages which is particularly important as I try to re-sign into my Uber and other accounts.  My bank uses 2 FA texts to let me sign into their website as well.  None of this is possible without receiving the short code SMS messages.

I find several older threads on this topic but none with a solution.  Other texts are being received.  It's just short code from any origin that I'm not getting.
