If you receive the Zoom error message 200: Address mismatch, verify that the address that you have entered under the Payment Method section matches what your bank has on file for the payment card that you have entered. If you are unsure, contact your bank to confirm the primary address that they have on file for your payment card.
If the issue persists after contacting your bank and confirming your billing address matches the address on file with your bank, submit a request to Zoom Billing for assistance.
