When you go to China Bank to exchange US dollars, whether you want to purchase foreign exchange or settle foreign exchange, the staff of China Bank need to examine, approve and put on record on the settlement and sale system of the State Administration of Foreign Exchange. There are two possibilities for you to have this situation. One possibility is that your ID number is the same as someone else's number, and the person with the same number has just approved or filed in the foreign exchange settlement and sale system before, so your number is not recognized; Another possibility is that a person with an ID number similar to yours has been approved or put on record in the system of the State Administration of Foreign Exchange, and it happened that the bank staff accidentally entered your ID number wrong. The result is that the system is preconceived and does not recognize your number.
In this case, it is unlikely that the ID number will be stolen, because the staff of the fake ID bank can generally identify it. Don't be afraid of this situation, because your number doesn't correspond to your name in the system. If there is a problem, you can easily explain it clearly. Your solution now is that you can use your other ID number, that is, your 15 digit can't be used, so you can use 18 digit and 18 digit can't be used, so you can use 15 digit. Most people's ID cards are 18 digits, and their household registration books are 15 digits. Or find a friend or family member and use them to settle and sell foreign exchange.
