My grandmother's ABC passbook was degaussed, and the bank said that I should reissue it myself, but what should I do if my grandmother can't go?

Hello, the passbook needs to be demagnetized and magnetized by yourself, but you can take your ID card, your grandmother's ID card and the passbook to the bank for a new one. When it is damaged, you can act as an agent. Folding and magnetization are two different things.

Oh, by the way, ordinary account conversion will not change the account number. In case your grandmother's account is an old passbook account (before upgrading), it is necessary for her to upgrade before conversion, because the change of account will affect the minimum living allowance, so you should pay attention. If it really doesn't work, contact the bank and they will help you find a way.
