Reasons why your ad account is locked when adding a Visa card: Using fake Facebook accounts or newly created accounts, these accounts are considered by Facebook to have low reliability. If you try to add a Visa card to your account, Facebook will block you. Visa cardholder name does not match Facebook advertising account information. The visa-added account often moves, logs in on many different computers, and uses many different IPs. The account's previous activity and spending history are not clean. This maybe because it used to run ads and owes Facebook advertising money. Visa card payment is refused or there is no money left in the account.
