1, one is to call the banking service directly, go to the manual service and tell the customer service your ID number. At this time, the customer service will check the bank card number according to the ID card provided by the user. If a bank has several cards, all the card numbers will be listed. As long as users provide their own card number and password, they can report the loss online. After reporting the loss, you only need to bring your ID card to the bank to reissue a new card. \x0d\ 2。 Another way is to go directly to the bank counter. When the user shows his ID card, the bank can check the bank card number with the provided ID card. The user also needs to provide the password of the lost card. If the loss is reported successfully, a new card can be reissued immediately. \x0d\ Note when checking bank card number with ID card: \x0d\ You need to have a certificate first, otherwise, the bank has the right to refuse to provide services to merchants who do not have an ID card to check bank card number. \x0d\ Secondly, it should be noted that you can only use your ID card to query your own card number, and the bank counter does not provide card number query other than your ID card, even if the other party is your own child or spouse, unless it is a special case stipulated by law. \x0d\ Thirdly, in addition to reporting the loss, you can also use your ID card to check the bank card number, such as customer remittance, fuzzy card number on the card surface, online banking, etc., so you don't have to go home to find a bank card, saving time.
