Apparently, Spotify requires address verification to try to ensure that all family members are in the same household, so presumably, those addresses need to be entered identically. Did my wife type out the word “bypass” in our address, or did she use an abbreviation? Did she put our box number on the first or second line? Wanting to make sure I got it right, I asked her to check the address format on her account.
