The verification text comes from your bank and not Apple. Your bank has the wrong phone number. If you have multiple numbers with the bank, make sure the number you want to use for verification is marked by the bank as the primary number.
>>Adding additional verification
A card issuer can decide whether a credit or debit card requires additional verification. Depending on what’s offered by the card issuer, the user may be able to choose between different options for additional verification, such as a text message, email, customer service call or a method in an approved third-party app to complete the verification. For text messages or email, the user selects from contact information the issuer has on file.
A code is sent, which must be entered into Apple Wallet, Settings or the Apple Watch app. For customer service or verification using an app, the issuer performs their own communication process.<<
