What exactly are you seeing? Typically, if Zoom's e911 provider cannot verify an address, it won't add it. You'll have to open a ticket with Zoom to have them reach out to their e911 provider to get that address verified. Now, it can go unverified after it was initially verified which is odd and something I've experienced several times. Clicking verify again could fix the issue or it could happen again and again.
