The card number of a rural credit cooperative bank is generally 19 digits at the beginning of 62 10, and the wealth management card, gold card and credit card are 16 digits. Rural commercial banks are joint-stock local financial institutions composed of farmers, rural individual industrial and commercial households, enterprise legal persons and other economic organizations. The business number segment of the bank card number has uniform provisions: the first six digits of the credit card number indicate the symbol code of the issuing bank, also called the BIN number, and different BIN numbers indicate different bank card institutions and credit card grades.

Due to the difference of each region, the number at the beginning of the card number in each region is also different, such as: 62 1033, 62 1457, 62 1459, etc. The first six digits of the bank card number can be used to identify the information of the issuing bank, and the difference of the first six digits also shows the different organizations and differences of the bank card. Before the reform, that is, when rural farmers were still in the era of rural cooperative credit cooperatives, rural credit cooperatives were all managed by the People's Bank of China. Therefore, at that time, no matter in which region, 62 10 was used as the beginning number.
