Generally speaking, issuing credit/debit cards by banks or credit cooperatives requires users to apply at the counter in person, fill in relevant application forms, and provide identification and effective contact information. If you didn't go to the rural credit cooperative to apply for a card, but two rural credit cooperative cards suddenly appeared under your name, there may be the following possibilities:

1. You used to apply for a credit card/debit card in the rural credit cooperatives, but for some reason you ignored it, resulting in two cards in your name, which need to be verified by the rural credit cooperatives.

2. It is possible that someone else used your identity information and applied for a credit card/debit card at the rural credit cooperative, resulting in two cards in his name. You need to contact the rural credit cooperatives in time.

3. There may be system errors or other operational errors, resulting in duplicate records of the rural credit cooperatives, which need to be fed back to the rural credit cooperatives and assisted in handling.

To sum up, if you find that the card number of the rural credit cooperatives is duplicate or the card number of the rural credit cooperatives has not been processed, I suggest you contact the rural credit cooperatives for verification and handling as soon as possible. At the same time, we should also pay attention to the security of personal identity information to avoid illegal acts such as theft or fraudulent use.
