Can the CCB social security card opened by Nantong children be cancelled in Suzhou?

It is impossible to cancel in different places.

2. You can only cancel your account at the Construction Bank where the bank is located. If telephone banking, online banking and other services are opened before the bank card is cancelled, these services need to be cancelled before the bank card can be cancelled. You need to bring your ID card and bank card to the bank counter to cancel the bank card.

If your social security has been withdrawn from city A, you can cancel it. If it has not been returned, or the relationship has not been reversed, you can use the old card. If not, you can open another bank card.
