At present, domestic credit cards are only made in Huangshi, Shanghai, Beijing, Shenzhen and Zhuhai, and no matter what bank's credit card, the production address is these places. After the bank's credit cards are approved, they are all distributed at random, so many credit cards will be sent from Huangshi.

For example, China Merchants Bank's credit card gold card was produced and issued from Huangshi, while its credit card ordinary card was produced and issued from Shanghai or Zhuhai.

Therefore, regarding the manufacture of bank credit cards, different banks and different card types may lead to different suppliers.
