I believe RW has a “real” phone number for my phone which is different from the assigned number which I see and use. The Assigned number is associated with this “real” number. How do I find out what that “real” number is?
Your phone only has one number that you can use. The underlying routing number that you’re referring to can change, can’t receive texts and isn’t designed for customer use. That all said, what problem are you trying to solve?
It seems to me that some App or Service I use requires the “real” number. Can’t remember which one just now.
I’m afraid that you can find more about that here and there isn’t a solution: Your phone number was rejected by Venmo, Twitter, a bank, or other third party service. Why?
