Credit card bills are kept for at least five years, and some banks will keep transaction records over five years, which is subject to the actual regulations of the issuing bank.

If relevant users want to inquire about relevant transaction records, they can only find records within 5 years or more, and may need to go to the bank counter to inquire in person.

If you want to use personal online banking or mobile banking, you can only query the bill information in the last year, and users can choose the query method according to their own needs.
